Almost Dyno tuned!
Well, my dyno tune day was today at Church's Dyno and well, due to my lack of knowledge, i'm gonna need another day. Anyway, here's what happened...a few days ago, i was having a problem with a leaky injector which ended up being an O-ring, so for the meantime, i put the stock injectors in instead of the 440cc ones that come with the SC. Well i forgot to put the other injectors back (440cc) and so once i got to the Dyno shop, we couldn't get a complete run because my car would lean out around 4800 rpm's. Well we got one run up to 5k before we jumped off the throttle and i have a temporary dyno run. Next week, i got another appointment and the 440's will be on and Sean at Church dyno said that he believes we can get 220-230whp with this setup (ARK N2 catback exhaust, 9lb pulley, CAI, s/c)...at least the way it's looking at this time. I think it's gonna be closer to 210whp, but it would be great to get 220-230. Anyway, here's the dyno sheet showing 182whp and 176.5 lb/ft torque at only 5k rpm's with stock injectors. Can't wait till next week!

haha, ty....that sucks that you couldn't go over 4500 rpm.....i would think you'll pull out around 220 whp, and maybe 200tq.....all those people say you can get 240whp out of the 9lb pulley, but i don't know about that

Actually, a SC with the same power does not reach peak power untill redline. Where a smaller turbo will hit peak pwer at say 5300rpm. So the turbo will reach peak power a good 1000rpm faster in everygear. That's why 250hp turbos are running 13s, and SC are not.
Plus, with a smaller turbo, boost comes in soon enough that while cruzing, just a little push on the gas brings boost back on.
But i have to say, I DO like the smooth power delivery of a good supercharger. Makes it feel like a v6 in our little sport commpacts!

A supercharger like we have might make 237 WHP, but it does it for zero time. LITERALLY. Max power on our S/C tC comes exactly at redline. That means you make 237 HP and immediatly have to change gears. You now start back over in your next gear with no power.
Look at the dyno above.
Now go to a turbo tC. You take off and the turbo spools up at say 3000 RPMS. You maxing your hp at say 4500 rpms (lets say it puts down 237WHP) at that rpm. You now drive with max HP till redline.
where as from 4500 RPMS on in my car, you are building to 237 WHP. And your going against a car that is at your max for the entire time.
TURBO TC IS FASTER!!! Not driver error!

14.7 here with the supercharger (9.6 in the 1/8th). On street tires I dont think it is possible to hit the 13's. Unless you are putting alot of power to the ground. And I only no one person breaking 300whp s/c.
It must be all drivers then. And if thats the case, then a S/C tC cant hit 13's, because it takes a driver to do it.
Slap some slicks on it, and thats a different story.

Thanks Nick.
1tc4u2nv:
the reasons we all stated that a turbo tc is faster then a sc tc is the same reason why you'll never see a sc tc in the 13s. Unless, like nick siad, he's on slicks and pushing some really high numbers.

yeah, i have seen other s/c cars that have almost a flat power curve, which would be ideal but with the trd, you only reach max power at redline, which is ridiculous, cause you can never run at max power ever that is useful....i used to have a stage 0, and that thing reached full boost at 2200 rpm......ive raced numerous s/c tc's and they never stand a chance.....man, i miss the turbo feel....but then again, the 3.5 v6 pushing over 300 na hp on my new z does feel great too!!

and Mr. Meaty:
I agree with you in that a SC tc will never go anywhere near as fast as turbo tc's have become, but never say that you'll never see a SC tc hitting 13's without slicks, because i believe it's possible without having to push 275whp+

I ran the 9.6 with only the Bosch 110 BPV.
I was never able to hit it again once turning the boost up, didnt have enough traction downlow. I bettered my 1/4 mile time, but not my 1/8th time.
I really dont think its possible to get down to the 13s without better tires. I hit 14.7 pushing 237 WHP. I dont see being able to drop 8 tenths off my time.
here is a question to ask, I ran a tenth better than you in the 1/8th, with the same setup (except I had the bosch 110, and 2 twelves in the trunk and 18" wheels).
Do you consider yourself a good driver? If you answer yes, then you kill the fact that the reason a person cant hit 13's is because of the driver.
If you say no, well then maybe it is driver error.
not trying to knock your driving or anything, just throwing it out there.
i think I am a decent/experienced driver, i dont see my times ever getting that much better in the 1/4 Mile (without tire changes)

I think you misunderstood me. I said you would not see a SC hit 13s UNLESS on slicks AND pushing high numbers.
I should have said high numbers for a SC, not just high numbers. I consider 250hp high numbes for a SC, just cause most aren't hitting those numbers.
