I am going to the Feb. 05 double driver's school at Roebling. My car which is pretty much H1 prepped but so far has been a DE/track car will fit fine in the SPU class although in SEDIV SPU runs up to 2.5 liters instead of 2.0 liters like most other divisions. At the Al. Region Barber race there was a BMWCCA prepped 3 series and a Lotus Europa running in SPU. Anybody run their H1 prepped car in that class? Hell I am. Hopefully some NASA too in 05.

You can run in ITE if your region has ITE.

 

Sam Lockwood (Raceworks) runs their H1 Del Sol in ITE and SPU.

 

Thanks. Most regions in SEDIV don't seem to run ITE although I see there is an ITE class in the schedule for the ARRC. From looking at H1 fields at least at Road Atlanta and what Roebling, it does not look like a lot of H1 cars run in my neck of the woods. They had what, two at the last Road Atlanta ECHC? Still a fun damn car though. In SPU you might get from two to six cars in your class in SEDIV.

Turn out in SEHC has been low this year, but I think things will improve a lot next year. SEHC came into being out of nowhere this year and didn't get any exposure until after the June RA weekend. The growth is there .. plus we have the best tracks down here!

We had 5 H1 cars at the June RA weekend, but only 2 at Aug. ECHC is getting 10+ most weekends now. Stay tuned for 05, will be another great year for Honda Challenge.

 

You can run in SPU, but the SEDIV rules now (since this year) require SPU cars to meet with Production Car & GT safety standards. This means you must have a fire system, fuel cell and the cage needs some extra bracing not required in IT/HC type cars (mainly the "foot braces" at the front of the cage).

ITE isn't a commonly run class in SEDIV except at enduros like the 13hr at VIR and the ARRC (maybe some other races down here).

 

You know I thought that too about all the extra safety equipment and at Barber there was a Mini (turbo) in SPO that did not have all of that and it had hit the track. That was confusing to me. Maybe ITE needs to make a comeback.

Yes, a very old thread. I searched and this is what came up.

Currently- anybody running an H1 car in SPU? My DE k20 civic is about to get caged. We don't have much H1 in South Florida so I want to apply SCCA rules to my build. I am about to have it dismantled to cage and of course a fire system. Brad no plans for a fuel cell.

Can anybody chime in here on this topic?

 

Why SPU?

You could run STL maybe or STU pretty certain but I dont know all your mods..

 

I have not read STL but will. I was told there is a fast bunch of Evos and Wrx Sti cars in STU.

95 EG with K20, header, RBC, injectors
Quiaffe LSD, 4.7 final drive, stage 2 clutch
Koni yellows/GC - camber adjusters
- don't know if this maters but installing 1" MC and ITR front brakes (the car stops decent but the pedal is pretty deep)
205 R888s, wanting to go 225 and looking forward to slicks when I can tow it there (driving it 2 hours in rain on 95 blows!)

 

No JDM motors allowed in STL currently, there should be a revision so next season people can run them. You would have to take off the manifold most likely and run the original that was on it. Detune the cams.

STU you could run it the way it sits. Take a look at the Kings civic they have been running in STU locally in the road race cars fs thread. They did pretty well with it but there isnt all that much competition. There could be fast cars in STU but from what I have seen regionally, they arent and you would b fine. Fastest local guy in STU is Irish Mikes BMW and I havent seen him out there much locally.

 

Yeah, I'd try to fit it into the STL box if at all possible... should be more (and better) competition there. The rules for the class are still getting tweaked a little to account for the availability of things like JDM motors and, depending on the cam lift, you might be able to get an allowance for the stock/OE cams. Maybe. Are you on improvedtouring.com? There's an STL subforum there... post questions/concerns and you'll be able to get some good info/responses.

 

Thanks guys, I will look at the site and dig a little deeper. I certainly have time, turning my car over this week for a dismantle and custom cage.

 

Long standing joke between us and a few fellow SCCA racers about SPU is that SCCA created it so my dad would have a class to run a b16 swapped crx in way back around 2000 2001 when he started racing. At the time there was no class in SCCA that the car would qualify for because of the motor swap I believe. Long time ago, I was young, hard to remember. There were multiple things but the motor swap rings a bell for me for some reason.

I'm sure creating the class had already been in the works, but the timing was perfectly halarious. SCCA(specifically the head of SCCA at the time) actually recommended the NASA honda challenge series to us when there was no class for us to compete in. Shortly after the recommendation word came out that they just created a new class in the mid-atlantic region that seemed to be a sort of catch all class in which you could do just about what ever you wanted provided the car had under a 2.5L engine. Fit the bill perfectly for us so we jumped on board. Ran unopposed for the first few years which was pretty fun. Looking back, wish we would have gone with the HC series. Would have been nice to meet some other honda guys and actually race against some other hondas. I think the reason for the 2.5L engine limit is so cars would remain in the small bore run group. To my knowledge SPU still isn't a nationally recognized class. Had very limited involvement with racing in the past few years so that could no longer be true. Just haven't had the time or funds to keep blowing up motor after motor.

Over the years I've seen everything from baby grand national mini stock cars, a mazda rx3, an old imsa car, bmw's, integras, and well, our crx just to name a few of the more memorable ones.

 

Correct me if I am wrong, but I am pretty sure K series swaps are not STL legal. I know for sure B18C5's are not allowed, I would think the same applies to K's.

I can confirm that ITE and Super Production classes (SPU, SPM, SPO) are considered regional only classes and you will not be able to run them at a national level event. Not sure if that matters to you.

 

Do tell. I have little knowledge. I have read NASA and Hinda challenge. My car clearly H1 but again we don't have enough HC action here and I want to build the car knowing what I am building for. It's about to go under the knife for cage build, brake upgrade and all needed safety stuff. I was asking some guys testing and tuning at the DE that had ITS and ITR cars for scca. They thought I would be SPU.

 

K swaps are legal but they have to meet the requirements for class allowances for lift (.425 i/e) and compression at 11:0.1 unless an exception is made. A k20R motor would not be allowed although I dont think its in the rules. STL is 2.0l and under.... K swap is going to be hit hard with weight though (2700 lbs). You can run big brakes like wilwoods, ITRs, etc fitting under the rules allowance of 290mm so an 11 inch kit comes just under that.

STU before SPU.

STL will be a class you could do well in even with a de-tuned K motor.

GCR http://scca.cdn.racersites.com/prod/...dSeptember.pdf

 

Check your regional supplemental rules as well as they may have additional guidance (especially for regional class like ITE or SPU) that the GCR does not address.

Also, STU or SPU allows for aftermarket big brake kits (like Wilwood) however in STL you are limited to OEM based options (within certain limits). For example my 11" rotor with NSX calipers are STL legal, a Stoptech or Wilwood kit is not.

It is daunting to comply with a SCCA GCR ruleset. Like you, I had already built my car quite extensively before making the decision to turn it in to a full on race car. This makes it even more frustrating to fit the car into a certain class and still be competitive.

If I had to do it all over again I would buy a car already prepped for a given class, or just start from scratch with a car that had not been modified.

 

That is not correct atmosfear. You CAN run a big brake kit like I said above. I just ran the class last season with an 11 inch 4 piston wilwood kit, its in the rules.

G. Brakes
1. Unless otherwise allowed in these regulations, all OEM brake
system components must be used.
2. Rotors - The standard production rotors or any 1- or 2-piece ferrous
rotors that do not exceed 290mm in diameter and 28mm in thickness
are permitted.
3. Calipers - The standard production calipers or any 4-piston or
fewercalipers may be used.
4. Any alternate OEM master cylinder and/or booster are allowed, as
long no modifications are done to any other component for installation.
5. Modifications may be made to the foot pedals to improve the
comfort of and control accessibility to the driver.


I was in the same boat, typical Honda guy that already modified their car to find out I didnt fit many places. STL had just come out like a year ago so I fit there with only making an engine change. Basically you can run a B18B, B18C, B16A, K20, at the rules provided. You can submit a letter to have the K20 compression allowed at oem levels and better do it soon so it can be reviewed before next season. The cam shafts wont be allowed and will need to be ground down to max lift at .425 i/e....duration is open though.

Miami if you want, I can submit the letter for compression, they just did this on a toyota motor to allow its 11:5.1.

 

Yes daunting. At this point, I totally agree I would buy turn key, car, trailer, tow vehicle. A total package. Knowing I need to start towing and stop driving to the track, I have to budget for tow vehicle, trailer and set the car up safety wise. Looks like I will be racing on sloppy spring rates for a while, LOL.

 

Miami I submitted the letter for you, it looks like the rules say you probably could run the oem compression as long as everything else meets the rules. I submitted for clarification anyway.

Which K20 did you have?

I also submitted for clarification on Ineligible motors to exclude all K20R motors and the B16B since they aren't listed.

It took awhile but I think they will be releasing my request to give STL the same air dam/ front splitter rules as STU providing an aditional 2 inches looking from overhead along the profile of the front fascia...so pimpy work can be done for down force. That will be released in the fast track news on the 20th for next season.


Its not too hard to comply with the rules, you kind of have to decipher them though. I have a friend on the ITAC committee so I normally ask him if Im not sure. I can help you clarify things if needed. I scoured the rule set while I was building my car for it several times so I knew what was and wasn't allowed.

 

Known- thanks. Too cool. I started reading the link you posted, but its Gonna take about as much time to get through as the bible.

My motor is k20 a2. (Was a 2003). Again it has RBC, header and I guess injectors. Not sure what the throttle body is and if it matters. I am trying to sneak it out on Homestead this sat for a half day, try to finish off the tires and front pads then turn it over to the cafe builder.

Again I will read the rules but I guess I am not smart enough for some of the language. I was planing to get front LCA's from kingpin, do you see that as a potential issue?

How's your rebuild going?

 

Kingpin makes IT legal control arms so they are legal for the higher classing ST is. STL is basically like SCCAs version of Honda Challenge open to all makes. The rules are pretty easy outside of engine specs. The rbc intake wouldnt be legal if it didnt originally come on that motor, same for the throttle body. The intake side needs to remain oem.


Here is a decoded list to get you started:

You can gasket port match the intake manifold

titanium retainers and valve springs are ok
Fuel injectors are open
Ignition is open
Computer is open, so kpro is fine, motec, etc
Adjustable UCAs are ok
11.4 inch 4 piston brakes are ok
4 wheel discs are ok
type r 5 lug ok
1 inch MC ok
Adjustable rear toe, rear camber are ok
225 max tire width starting next season
17x7 is the biggest wheel allowed, 7 inch wide is limit so 15x7 ok
rear spoiler is ok as long as it fits the rules, I had a hard time with this so I just went with the spoon copy duck bill
any sway bars and reinforced sway bar mounts like ASR are ok

The roll cage is the thing you would want to get looked at by a good builder, you can go through the firewall to the shock towers unlike other classes and have several pick up points inside the car. The weight you would run at (2700) you might want to add more weight in areas like the cage. I ended up having to bolt 150lbs to my passenger floor to make weight.

I went with an IT or Improved Touring legal cage so I could drop down to IT or vice versa down the road.

So its pretty much open to the mods we all make on these cars outside of the motor. The B series VTEC motors are limited by the cam lift as well, so .425 is just above oem specs. Remember the duration is open so you could get some custom grinds done for the K20 using your stock cams or after market. I was running Brian Crower under the limits.

The rules are overwhelming and Im not sure why they dont make it easier for people new to SCCA. I was lucky and had a bunch of friends help walk me through it all so I dont mind helping at all. I was worried the old mans club SCCA is known as wouldnt be friendly to me, but it has been terrific from comp school to the races.

Do you have a comp license yet? I know you have a lot of chump car experience and track day so if you contact their officials for that you might get some credit so you only need a day of school instead of two, or maybe need no school at all. If you want I can get you the contact info for the lady for our area.


My build is stuck right now, I have the motor at the engine builder and have been waiting for 3 months on my new crank scraper and windage tray. Once thats done and with my builder it shouldnt take long. I just need to install my new double adjustable konis and throw the motor in and get it tuned. Im hopeful Jan or so it will be running and ready to go.

Let me know if you need anymore help.

 

I am either retarded or they changed the rules from when I started putting my car together. A big reason why I went with the 11" rotor and NSX caliper is because I was under the impression the brakes had to remain from the manufacturer, but not necessarily the same car. Clearly I was/am wrong.

Sorry for putting up incorrect info, the GCR gets posted every month so maybe I should check before opening my mouth.

I am still on the fence as to what class I want to run. I cant run SPU or STU because of the supercharger which leaves ITE only for me. I cant ditch the supercharger and run STL because I have a JDM ITR swap. I too left my cage IT legal so that I had the option of running IT classes should I elect to go that route.

I still havent made a decision, for now I am just running Time Trials events in the car and having fun with it as is.

 

You would have been right in 2011 STL is new so they have been constantly changing rules to get it right. I think down the road it's going to be the class for us east coast Honda guys with swaps. B16 is the way to go if you can get down to that weight.

That's a tough one with f/i and an ITR swap. Sell them? TT is fun and so is power, but I do enjoy the w2w more.

ITE is like non existent here.
