Hey guys havent been on here for awhile. Just getting a tick mastercylinder installed hoping that my car will finally shift decent. Anyway Got a 01 Z06 with 6spd heres the mods
stock short block
A&A Vortech supercharger kit. 3.6 pulley 10lbs boost
fully cnc ported 243 heads
CamMotion cam 585 lift 114 lobe sep.
ported fast intake
ls2 throttle body
lingenfelter 100mm MAF
IAT after throttle body
alky injection
full tubes
60lbs inj.
BAP and lingenfelter fuel pump
Spec stage 3 plus clutch
Car made 592rwhp with 18degrees of timing at 6500. Why cant I get some more power out of this damn thing. Theres guys on here with alot less making 700rwhp. Where am I going wrong? My friend has HP turners. I was ganna bump the rev limiter up to 6800. Any other suggestions with this thing. Dont get me wrong, 600rwhp isnt bad I just figured it had way more in it. The guy that tuned it is suppose to know what hes doing but he tunes everying not just ls cars. let me know if you guys have any suggestions

 

Your setting good for the boost your running on that setup. I was very close to those numbers with basically the same mods, timing and boost (AFR at 11.5). If you want more power, go to a smaller pulley. I gained about 50 rwhp by going from a 3.6" pulley to a 3.4". Just be aware the stock block might night like the power for long....

 

im in the same boat as you. High numbers come from right boost timing AFR. I have similar mods to you. stock block, 3.6 pulley, ecs blower cam,60 inj, 10psi, stock compression. Ive even switched to e85, but i was able to lift my timing only by 2-3 degrees before getting knock again. What are your timing numbers on 5200rpm? I use to run 13 on regular gas and now i run 16 deg. at max torque on e85. on very top rpm my timing rises similar to yours. Also could you post your tune and log, what gas you made these numbers with?
If you want to get a little more out of it go to the dyno with higher octane gas and try more timing. if you still will get knock make knock sensor less sensitive.

 

Your cam specs don't mean much without the duration.
You didn't say what AFR you tuned it to.
Did you incur any belt slip? If you say "no" how do you know? Do you have a way to log boost?
If your fuel system is handling your current demands, I don't see it handling much more anyways.
Without looking at logs and the tune, there's no way anyone can tell you how well it's tuned.
They're pretty good #'s anyways.

When you say there's guys with "alot less" I'm curious who you've seen making 700rwhp on a stock short block with 10psi boost and what you have that they don't.
I think you'll find out that you might just be being hard on yourself. (or your car. )

IMO boost is a great equalizer. We've seen stock motors make that kind of power with just a supercharger added.(possibly with more boost) Maybe you just have something in your combination that isn't as boost friendly as others.

 

700 hp seems like a lot to be making on a stock bottom with only 10lbs of boost. Also the dyno is only a number and there all different. If you take it to a different one you might make 50 more or 50 less. My buddy has a 402 with 10.7:1 comp with all ported and polished allpro heads with a blower cam also a upgraded fuel system and he is making 717rwhp.

 

With how much boost?

 

Well I was reading on here there was a guy that made just over 700rwhp on stock engine. "But I dont know what the boost was. Maybe I better be happy with what I have by the sounds of it! I believe if I remember right at 5200 im already at 18 degrees already. The guy who tuned it never gave me any info. I have no info, just what my friend pulled out with his hp tuners. You guys will have to bare with me a little. Im new to this tuning buisness I will see where the afr is tuned at. I dont beleive there is any belt slip but exactly how do you know!lol Really have no way to log boost. Just a gauge in the car. My fuel system is handling the load with no problems. Dam I cant find the specs on my cam. Im thinking the cam is holding me back some. Just my hunch. Thanks guys I dont feel so bad about the numbers anymore. But the funny part is im deffinatly ready for more lol. But theres gatta be a point of quit ya know. Always ganna be someone faster and with more cash. Gatta be happy with what we all have because alot of people will never get to own or drive what we have. Thanks guys Ill let you know where im at with the timing and afr this week

 

I have a feeling the next 100rwhp is going to cost you bigtime.
Fuel system upgrade, maybe clutch, tires to hook it. blower pulley, retune etc.
It does get expensive. Certainly a hobby rather than an investment.

 

On my 02 Z with an A&A kit V3 SI with a 3.8kit shorty headers and an off road pipe I put down 596rwhp seeing A/F about 10.2 on a stock block which seems pretty rich. With that said I put on a set of kooks LT headers, x pipe, changed out to a 3.6 pulley and added a snow meth kit. I'm seeing 12.2 A/F full boost and putting 710 rwhp street tune, and waiting for the stock block crap out and everyone taking bets on how long it lives. Thinking of putting a YSI on it and just see what the limits are....chime in Mike

Is it tuned to 12.2 and then the meth added on top or are you showing 12.2 on your AFR's with the meth activated?

 

Brett give me a call if you get a chance I just got off the phone with Snow, but I want your thought on this especially after talking with a few guys.

10 lbs of boost

 

I'm really new to supercharging, but the numbers the OP's getting, with his mods, seem right in line with my expectations. My VS3 setup is about %80 installed, and I'll need to do clutch before I can dyno tune it..it slipped before on the dyno when is had about 480 RWHP NA. I expect to get about 600 RWHP with 8lbs of boost when I get it all together.

 

12.2 with meth activated.

 

He has a stock bottom-end and he's complaining because he
doesn't have 700 rwhp. I feel you are doing pretty good with
almost 600rwhp. That challenge will be controlling what you
already have. All of these numbers don't really mean anything
in the real world.

 

Impressive!

You're already running on what I consider the ragged edge, so what happens when (notice I didn't say if? ) your meth quits or even studders at WOT?

Just sayin'

 

No way. Guys just run meth for safety.

 

Go ahead and say it, because I won't . I think anything over 650 is probably running on the ragged edge on a stock block. Most tuners will tell you anything over 600 might live for a while or might not. Two years ago I'm sure people would say if you hit over 600 on a stock lower it it would grenade on the dyno. I fully understand and know what will happen not might happen over time. I'm guessing a ring landing will go eventually if I stayed on this set up for an extended time.

When I took my car down to get tuned I figured it would pull some high numbers, but I wanted it as safe as what safe could be on my combo. The tuner actually could have pushed it closer to the 740-750ish numbers, but contacted me and said it's getting past the "ragged edge" so he started pulling timing back and ended with 710/582. I called him today, because after reading multiple post the general consenus is that it's to the lean side gave me reason for concern, but he doesn't feel it's lean. I'm not sure if tuning a car at a higher altitude makes a difference targeting an A/F ratio. I am no expert on this and don't claim to be. I know the tuner said at 6200 and a 12.2 a/f zero knock it would live until the weakest link. Of course I have an extra engine that I'm getting ready, and it would make me feel better to see it backed down to mid 11's in the A/F department. Maybe I should just back it down so I can sleep at night.
I am also not an expert on meth injection, but after speaking with Snow today they claim that you can get away with a higher a/f ratio, but like blownblue said if the meth cuts out yep I'm probably screwed. I should do some sort of kill switch just in case. In the Snow manual it shows 12.0's-12.5's should be targeted. I spoke with a tech at Snow performance that told me that the meth injection would lower me about a point on the targeted a/f mixture and would not show up fully on a wideband (didn't make sense to me, but again dunno). Someone please jump in on this one that know's more on the effects of Meth injection because simply I just don't know. Sorry wildman if I butted in on your thread. I agree that the best way is take it down the track numbers are just that numbers.

Thanks, Bill

 

I think it may be best if you copied and pasted this into a new thread so we don't hijack wildman's thread any further and I'll be happy to give you my .02.

 

Im not worried about it guys, no biggie
