Yes - that is correct.

i dropped down to the 9lb pulley
next i will look into going with a larger pulley on the backside the one that connects to the blower pulley that was vortech advice and of course the 928 impeller
and with a little meth injection she should be making some good power throught out the power band

Nissan370 on what kind of dyno are you using to get your HP?

Nissan370 · 12-21-2011, 05:24 PM

dyno pack

He sold me his RE-11's, you think it says something bad about the tires? Or, maybe it has something to do with the fact that he wants an M3 and parted out his car.

Um Nismo, you aren't quoting the PM dyno are you? They have a very giving dyno, they know about it too and they'll tell you that their final numbers are not the point but rather the deltas when using their dyno for tuning purposes.

1.) how much more power can we get with a 9 psi pulley?
2.) My auto guy said changing to stillen cats with another tune, we might get 30 or even 40whp?

thanks man!

Nice numbers man, I'm getting my Stillen SC installed in the next week and the will be out to Kaizen for a tune.. Mustangs are good dynos IMO. True numbers.

Yes if you run HFC's or TPs you should see another 30 WHP.

That's not true on our cars, with TPs he will actually prob see a loss of HP due to the valve overlap.

Who told you that? numerous people and tuners I have talked to said there is 10-20WHP to be added with TP's or HFC's,. Lets not count the numerous dyno sheets I have seen where guys are making 10-20 more WHP and WTRQ more than me and the only thing different they have are TP's or HFC's.

WOW mis-facts are nice. :/

You get the bonus from changing HFC's on an NA car but some say you loose it with an FI setup due to blow through due to valve opening overlap. I think there was some supporting dyno's for this theory but can't remember where.

In general or specifically on our engine? Check out the numerous GTM stage 1 SC threads, there was actually an entire thread dedicated to trying to get more power out of the SC with exhaust. Due to VVEL the intake and exhaust valve overlap is too aggresive for an FI application and causes us to loose boost through the exhaust. For example I'm running the 928 impellar AND the 9 psi pulley and I'm barely breaking 9 PSI on my Stillen kit with full exhaust

??? So Will I have issues with boost on my car with just a CBE? Thanx for the info.

Since you posted before I could find the thread, here it is:

GTM Supercharger Stage 1 w/ F.I. LTH

No, you won't have issues you will just make less power. Do some research, a lot of us run full exhausts with FI and are still getting great numbers.

Nissan370 · 12-27-2011, 12:21 PM

Ya overlap is a problem but guys are still making great power
This is a short run I did with the 9lb pulley,HFCs and cat-back
Yesterday.

Just like the post above your making less power per psi then a vehicle with same setup but control over the cams
