Mustang Dyno #'s on pump 91 & meth
Mustang Dyno #'s on pump 91 & meth 532hp/490tq @ 5700rpm the dyno was having tach signal issues so that was the best graphed run. My setup is a 370ci w/11.2cr, D1sc@10lbs, fast 92/92, Ms4 cam, Prc stg 2.5 Ls6 heads, Built 4l80e, Pro Yank 3400, Lt's, Loudmouth, March underdrive, and 3.73's in the stock 10bolt.
I think I may need a bigger jet for the meth kit and my 50lbs injectors are around 130% duty cycle @6400rpm . Timming was at 20-21 degrees on this run I think.

Thanks, im happy and then again im not. It had made 410hp na but that was a full pull so I guess there was more left that I wasn't able to see untill the dyno gets fixed.

so because of the issues you couldnt do a full pull? and how dies it feel i have same heads cam n/a but havent beem on the dyno yet...
well going to a d-1 has been a thought right when i got done putting the car together

The car feels gooood.
Yeah the motor was built for a 200-300 shot of spray which I was going to do, then I let a friend talk me into buying a procharger so here we are. On the runs my IAT's would start around 78 then drop to about 74-75 then end up creeping up to the 80's. So I called AIS about the meth kit I got and i'm only running a 5gph jet mixed 50/50 meth/water. He told me to keep running it mixed I needed twin 7gph jet's but that he would go 100% meth and use twin 14gph jets, so I ordered the dual 14's.
Thanks for the replys guys keep'em coming and i'll be sure to post up when I go back with the new jets.

1) How are you running a ASP underdrive pulley with a blower crank pulley exactly? Im guessing that is a misprint.
2) This heads/cam combo is a bad choice. You could put a stock z06 cam with stock 6.0 heads and likely make the same power with no blower pulley change and get 5-6 degrees more timing in it.
This seems like a bad combo for a forced induction setup... Sell the heads/intake/throttlebody/cam, put stock ls6 intake/6.0 heads/ls6 cam in it, put $2k+ in your pocket and make the same or more power safely.

I agree, other then the cam. I'd get a custom spec'd blower cam from somebody in the know.
Something doesnt seem right. You have alot of compression,meth, a big cam, decent heads, and a D1 running 10 psi and only made 524?Granted it was only to 5700, but you still should have been much higher.Was there any knock on the run or high IAT's?Although with meth i doubt the IAT's were that high.I also dont think the cam would hurt the setup.Its not like a turbo car that can be more picky.

No misprint we drilled and tapped the front of my March underdrive pulley like a sb 350 and used a spacer that procharger uses.
2) This heads/cam combo is a bad choice. You could put a stock z06 cam with stock 6.0 heads and likely make the same power with no blower pulley change and get 5-6 degrees more timing in it.
I know it's no where near the ideal setup but as stated before my plans did a complete 180 from what started. And I am spraying no where near enough meth as the kit I ordered was spec'd for a Subaru.

My Iat's started around 78 degrees then dropped to 74-75degrees when going wot then just crept up into the 80's. That is why I thought I wasn't spraying enough meth/water. I picked up very little knock on a pull or two but I dont remember if it was on this pull or not.
I'm hopeing that going from 50/50 meth/water with a 5gph nozzle to 100% meth with twin 14gph nozzles my #'s will go up.

Number 1) nice #'s.
Number 2) Your single meth kit is fine.
Number 3) You need bigger injectors or a 2nd fuel pump.
Number 4) Your compression ratio is a time bomb for dissaster.
All in all, take care of your fuel system. You can pull to 6500+rpm and have more power. But, your compression is too high for forced induction. I see a motor rebuild in your near future. And maybe a rear end + a build tranny.
Sorry for the doom and gloom. Best of luck.

I agree. Its the compression. If you are going to run that high of compression you won't be able to run much boost without risking engine failure. JMO, but I don't see anyone running compression like that with any amount of boost. I think I saw an 11.2 to 1 build with like 2 psi. It made good numbers and was safe, but if you are going to boost why build a motor that can only run safe on 2 psi ??
