You adding the flex fuel sensor with that super dope ems

wunfstgsr

I had a few issues using that AEM V2 EMS along with there full COP kit. Was all brand new too, coils burnt on the dyno and after i sold the EMS it failed on the new customer scary.. Lets just say i went back to hondata and a oem distributor setup. But i really want to get that flex fuel sensor on my new setup soon.

My aem box, epm and k coils never gave me a problem

Just going to be running barrel e98 since we live right next to a plant. No need for the sensor and it will just be a track car, will not be street driven at all.

Has anyone run a C38-94 rotrex unit on a b series yet?

JRCivic1

Do you mean the C38-91/92 ??? MOTORVATIONS is working on one. It should be ready for testing soon.

jdmlooks

Sorry for the delay, we are working on some ignition issues so stopped at 7k the other day. We are at 322/240@7k on a mustang dyno on e85. We fully intend to run this out to 8200 and still have around 5 degrees of timing to add in the midrange and up top. Stay tuned.

Chillinit

Any update?

Ran into some ignition issues, so have been running the car at 7k, performing great so far.

Anyone running a traction bar? wondering if it will clear

JRCivic1

I still have one on my chassis... I will let you know if it clears when I install the supercharger kit. The engine now sits in the car, and while installing a new Deatschwerks 330lph fuel pump on Wednesday, MVM found RUST in the tank !!! Ordered a new tank... It should arrive on Tuesday. Start up and break-in should occur next week... then install the supercharger kit and fabricate charge pipe and the intercooler. I hope I can clear the traction bar so that I can keep it... I will need it to try and put all of that power down !!!

Did you re-tune yet ???

It shouldn't have a problem clearing a traction bar.

About to order the Go Autoworks intercooler kit to complete my KW kit but was wondering if anyone has sound/video clips of the differences between the HKS SSQV and Tial BOVs. Not sure if the difference is the same as turbo cars. Also has anyone used a header other than the Alpha/Megapower?

It will sound basically the same as a blow off valve on a turbocharged setup. The only supercharger type that really sounds different using a BOV is a roots/screw type.

Personally the HKS SSQV is so annoying to me. I just can't stand the sound. Also with the large number of copies floating around and their quality makes it hard to determine if one is real. Contrary to popular belief they can leak and their design has caused surge problems on certain setups. Since they seal under pressure and don't have any way to adjust the spring preload/tension their design can actually cause them to open slow enough to create compressor surge. If you use the wrong insert it can make it worse.

You'll find that having a valve with adjustable spring preload is crucial. 99% of the time having a BOV without adjustable preload causes lots of issues with proper valve operation. Having a valve that stays open too long under vacuum or it opens too late once the throttle is closed or one that has too soft of a spring can all cause drive ability and reliability issues (as far as the turbocharger is concerned. This is most important with journal bearing turbos).

I can't tell you the number of times I've had to work on cars with BOV issues (mainly SSQVs or cheap valves, shoddy piston types, or eBay clones) that caused drivability problems or surge was killing turbos. I also spent a lot of time "tuning" the adjustable type valves for proper operation with minimal surge and the car owner would comeback and report how much better it drove. This was also true for setups we had to change to an adjustable valve. Ultimately the amount of boost you plan to run in conjunction with the base rate of the spring in the valve dictates just how much adjusting you can do.

Typically if you run the valve at a stiffer setting for high boost then at the positive pressure threshold/lower pressures you run into tons of surge. If you go the opposite way to too soft then you can wind up with a valve that stays open too much under vacuum/partial load or at high pressures when you ease off the throttle (not off entirely) the momentary pressure fluctuation between the pressure in the charge piping and after the throttle body can cause the valve to leak or open/close rapidly.

The TiAL spunds more like a "chuff" sound with a low pitch. If you've ever heard the pressure valve on an air compressor open it sounds similar but deeper. Typically with your usual exhaust noise it can be hard to hear from inside the car but they do a good job of eliminating surge.

Sound clips are all over youtube.

I personally would stay away from the SSQV, the TiAL is a bit large for your application. A turbocharger maintains a fairly high shaft speed longer when the BOV opens but since the supercharger speed is directly related to RPM as soon as you let off the throttle it will stop generating positive pressure almost immediately and airflow also drops off quickly unlike a turbocharger that basically "free wheels" for extended periods of time. This means you don't need as large of a BOV for your application

Something like the older Greddy Type S, RS, or the new RZ valves would work perfectly and sound decent. The one thing I like about Greddy valves is they have a lower fitting under the diaphragm called a "boost assist port." If you're having issues with the valve responding fast enough or you get surge here and there then you run a pressure signal from the charge pipe the valve sits on to that lower fitting and when you let off the throttle the pressure under the diaphragm actually forces the valve open when the top port sees vacuum. The older HKS racing valve (not an SSQV) also works great and sounds great. Turbosmart just came out with a new BOV that's very compact but flows like crazy and is a rock solid product. If you wanted to go really old school and have a unique BOB then something like the Prof Sheepdog or ARC valves would work well.

I have one of the last versions of the Prof Sheepdog and an ARC for an R34 Skyline. Both are compact, simple, efficient, and sound amazing IMO

Sorry for the long post lol.

I still have a genuine HKS SSQV from back in the day, and won't sell it. I was able to change the valve sound adjuster (plastic) to make it sound more reasonable.

I'd look into the Turbosmart Series. Especially the Vee Port and Dual port universal valves. Much easier to integrate at a nice price, and do a lot better without risk of clones or eBay copies

I was thinking about getting the Greddy RZ since it'll mount to my current RS flange. The RS works great though so I never pulled the trigger.

Although my kits not a KW my Pro charger uses there Big red open race surge valve, I freaking love this thing! the sound is just unlike any BOV i have ever heard, almost like a water fall surge of air at idle and between shifts it has a wonderful deep sound! It can easily be used on these kits as well! i wish i had a sound clip but when i had my kit on it sounded pretty much like this sound clip,

When i ran 6 psi i used a authentic HKS ssq BOV i got brand new from a HKS dealer but when i increased by boost to 12 the HKS could no longer keep up and created compressor surge so i upgraded to this one and it no longer has surge.

ibeen following this post for sometime now and finally decided to take the plunge and buy a kit about a month ago. its all assembled and running but im in the process of sourcing the right belt before strapping it to a dyno. im very anxious to see what it makes, as of now its street tuned and we logged 18 psi at 8k rpms, its setup to go to 9 so we should see a couple more lbs by then.once the belt arrives ill strap her to a dyno and see where we are.

setup consist of a motor i built in the beggining of the year witch made 245hp all motor and ran 11.9 in a eg hatch.its in an em1 now so thats what made me get the kit,to pull the extra weight along

tb motorworx cnc head

stage 2 cams

css 85X89mm 13.xxx compression

sk2 ultra street ect ect

ill update once i tune it should be sometime this coming week,here are some pics of the setup old vs new.everything was installed and built inhouse by me at ALR.i still have alot to do to finish the car(catch can,overflow,better set of headers with more clearance ect ect) but the foundation is there ill finish the rest during the winter after i tune it.......enjoy

Super clean setup, I like it. What fuel are you running? Even with CSS that's really high for stock sleeves so I would be curious to see how reliable it is (I'm going to CSS my F22A1 and run 12:1 static at around 450-500)

Also what are you using for an intake? Getting the filter out of that hot air would definitely be an improvement all around.

If people can get these kits to make the power they are capable of then I think tossing one on something like a high compression B16 and putting it in a gutted CRX would make for a seriously fun BS mountain/time attack car.

im on e85, im not concerned about the sleeves the weak poing is the piston imo .the wiseco all motor pistons have smaller skirts then most and come with lightweight wrist pins but so far so good. i been beating the bag out of it since the street tune the only issue as of now is my belt slipping in 4th gear but the new belt should be here anyday now
