I never have on any car I have owned.... and I would say only 10-15% of the ones I tune have them done. Never had a failure yet... supercharged or not.
NOTE: The highest reving one I tune shifts at 8,400 and has never missed a beat and is a road course car, that is going on 4 years of racing...
Technically it doesn't really matter much as long as its there. Honestly folks like to argue about pre intercooler and post, and even that is a drop in the bucket.
The only thing that honestly matters is...
1) it works
2) its far away from the MAF
You can either do the full conversion to the 8 rib (dedicated drive) which is pretty pricy... Or just run an overdrive balancer for now which will net you a larger crank pulley and a bit more boost (fairly cheaper alternative).
Sounds like its an HO kit with shared 6 rib? If so you will need at least a 3.50" and a few more RPM to get there. I personally don't like going smaller than that, due to the possibility of belt slip due to the 6 rib
Send me your file, and I can make it get 20+ more MPG's (at least by what the dash says lol)
However, most supercharged cars will always be the same MPG's as stock, or like 1 or 2 mpg's higher when driven exactly the same as stock. (Due to the pumping losses being reduced, and some other...
If you are going by what the dash says, it will change with virtually every tune you have done.
Reason for that... 1) its just math and 2) its a guess
So lets say the computer looks at airflow, + injector size + stoich fuel ratio + tire size,gear, trans, etc = estimated milage
If you change...
I know you did, which would work well for him. (Cause otherwise he would have to get a longer metal tube thats connecting to it).
Before going through the hassle of trying to find a longer tube and hoping the cobra coupler fits. Do you wanna just do another rubber tube thats properly cut...
The irony is that, if a person doesn't trim the elbow, it kinks to that shape and then the internet goes crazy about "OMG it won't flow, this kit is JUNK". (even though they are making 700-900hp) lol.
Those are neat hoses, but ideally its best to just get the normal 90 trimmed to keep it as...
So the way my GF and I do them, is....
We mount the blower first, then slowly trim the "short" end of the 90 about 1/4" at a time... each time sliding it under the headlight and up onto the blower outlet until it fits without a kink.
Then we clamp it tightly with the worm clamp so that it...
45% correction is MASSIVE. Like so large I can't believe it runs.
Make sure your fuel pressure is correct,
Make sure the part numbers for your injectors are correct,
Make sure o-rings around the injectors aren't leaking at the intake,
Make sure all PCV/Breathers are correct,
Logs will...
We have a one-piece silicon hose that we designed but have been waiting on it since like the beginning of Covid from the vendor.
That being said, I bet I have personally installed 20+ of these kits, and now my GF is on her second install, and I have never had that tube come off, or a worm...
Thank you for understanding. This is technically true for EVERY aftermarket product that involves a tune file. (There are just many that try and skirt around the rules, but bending them, or pretending they didn't know. Which with the fines involved these days, isn't something that should be...
No N20
8 rib Belt
Air to Air intercooler (screw blowers get to have air to water, LUCKY)
Fixed blower pulley sizes (blower can't be over-spun)
Unmodified P1X street blower
3800+ lb race weight
Yes, they are built motors, with the latest goodies. But 170+ MPH is crazy for the weight.
Easy...
Jim Summers was the man that did that, and the first 6.99. (ProCharger powered actually)
My father has the blower belt from that pass hanging in his garage actually. :)
Sorry man, but....since there is no way to "transfer" the tune, and ProCharger doesn't send out the tune more than once. The only way its 100% actually CARB legal is if its a new purchase, with the original file, and sticker for it.
I literally deal with the CARB every single week. So even...
