Im not sure if this is against the TOS but I was curious how many people use a boosted honda for Road-Racing.

I know an N/A application is probably better because of power throughout the powerband. But I was curious how many people on the forum used a boosted Honda for auto events other than drag racing.

Thanks,
Eric

 

what do you say an N/A powerband is better than a FI powerband?

I would disagree to the fact that with a properly matched turbo that will spool very fast and with the correct adjustments to your suspension to induce oversteer rather than understeer, I would say a turbo will help you pull out of corners and hairpins much faster.

 

i use my boosted honda for auto-x and hopefully sometime this summer road racing too

with who is this legal?

 

Maybe in a region with very lax SM rules? Or maybe he just does a lot of Fun Runs...

Whoa...that's pretty cool. I'm assuming though that's also open to like 900hp Porsches and such? In that case, I'm not sure how competitive a little turbo Honda would be, but power to ya.

I know but most people making some sick power on a turbo honda are not using a small a/r turbine. I want to build my car as an all around car, im sure I can make good numbers on a small a/r but I wont be doing RoadRacing that much so. For the MOST part, the car will be setup for 1/4 mile times though.

I was just seeing how many people were using turbo Honda's in roadracing and their experiences, didnt mean to start a FI vs. N/A.

 

while theres no series for turbo compact cars on road courses out there,
you can run one in the SCCA's ITE group out in the northeast. there was enough interest out that way to run cars that werent classified in the other IT classes cuase of either forced induction or just too fast. its pretty much a run what ya brung thing out there. and ive seen some turbo golf's in it, a nicely warmed up and seriously high revving itr, and a loud turbo 944 winged racer....as well as a pair of vipers with $20k paint jobs.....(that DuPont color change stuff)

so if you can get an ITE group started out west or wherever you are....then go for it.

 

I remember reading here that some members had problems with over-heating while road racing with a turbo honda. They then said, AutoX, drag and just plain street driving were no big deal, but it was road racing and HPDEs that cuased them to have problems.

 

If they were going to have problems, I'm sure roadracing/HPDEs would be the thing to do it, as that's the longest period of time a person would be pushing the car real hard. In either drag or autox the car is pushed, but briefly; on the street, you SHOULDN'T be pushing the car hard enough to overheat it, unless something's wrong with your cooling system.

Why would the rules have to be lax? Adding forced induction is legal in SM.

I run my turbo Integra LS on the road course. There is another thread or two here where I described the heat problems... It's mostly from the front mount intercooler restricting air flow to the radiator, but that problem should be solved now that I added a grill to the upper part of the bumper and did some other things.

My powerband is perfect... NA was such a joke compared to this. I'm running a custom built T3 (small, virtually zero lag, built for road racing), GS-R gears, Type-R LSD, and lightweight flywheel. The result is no noticable lag on the road course (no need for left foot braking), and very smooth usable power. I have much more power than before and the powerband is very wide. And because turbos make more power when there is more load on the engine, I can shift short without hurting my acceleration. I'm extremely pleased with the engine, and I really couldn't ask for any better. I think back on my days of being NA and think "why did I even bother".

The main hurdle in road racing a turbo Honda is classing. I'm not aware of any SCCA Club Racing classes that allow you to add forced induction, but there are Solo classes that allow it. I've been participating in the new pilot program for SCCA Time Trials in Colorado. We use the autocross classing, so I would be in SM, except that the safety requirements for running Mod and Prepared classes on a road course are a bit overkill for the majority of Street Mod cars. We have a local Open Street Prepared class that allows anything that can be driven on the street, and the safety equipment requirements are reasonable for such vehicles. After getting the approval of the event steward, we are allowed to run in that class.

YES YES AND YES!!!!
I couldn't agree more. You took the words right out of my mouth
My classless HPDE road course street car is fantastic. My experiences are the same.

 

I had a sick video with Top Fuel's turbo civic type R in japan on a track. It had no problems with spooling a large turbo. When it hit Vtec on the straits it sounded like an explosion. I just think it is a big advantage to boost, I think NASA U.S. Touring should allow turbocharging, since they have WRX's in their class.

yeah, because you can fully understand how a car functions from a video

I believe I read in the NASA rule book that going forced induction just moves you up two levels in the engine classes.

 

I've been wondering the same, I just have a stock (with a turbo) crx making 170whp/160wtq...but have the single core EG radiator with a front mount blocking it I dont want to be pulling off into the pits every couple laps to let it cool down, to only go out for a few more. Subscribing to see more info.

 

I miss the days of the Honda HR-series turbo V8 engines.

You sure about that one?

 

So if youre in H1, now where do you go? Back to the trailer, and back home

 

There's no FI in Honda-challenge. No bumping classes, its just not allowed.

You can run Super Unlimited (?) with NASA though.

And an FI Honda in SU would be a hilarious joke.

Although I am not sure it would get classed into SU, depending on the motor size. I do know that the yellow Miata with supercharger runs away with it in the small bore group all the time and SU doesn't run in small bore.

EDIT: You should also do a search. This topic has been covered many times in the past

Nope....actually don't think its NASA now, but I was reading thru some type of touring car rule book which had it. Can't remember which one now!

 

this is interesting.
