Crazy H.P.
I just went to the Dyno with my Holley upper and lower/10:1/ 327 all forged internals stock block/42lbs. inj./255 intank/T-REx Inline/AFR 185's/ 598 lift roller cam I cant remember all of the cam specs off the top of my head/P.M.S/S-Trim with a Power Pipe/ 6.78 crank and 3.0 blower pulley. I also have a Methanol Kit.(cause of the 10:1 compression) Without the Methanol I made 520 Rwhp and 500 rwtq at 4800 and ended up at 550 RWHP and 530 RQTQ at 5300. I mean the power is great and all but I cant use it with the stock block. I mean I can't shift at 5000 rpm with a 6300-6700 rpm cam not to mention my 3.73's gears and TKO 600. What should I do? My boost gauge is showing like around 15. I have never heard of anything making that much with 6.87 and 3.00. ( And yes I re-verified the pulley sizes) I guess I am going to put on a 3.33 Blower pulley and see what happens. Maby then I cant use the Meth and make aorund 550/550 at around 6200. I guess we will see. Any suggestions would be greatly appreciated.
Thanks!!!!!
:rolleyes:

That sounds pretty good. Some may have to do with the higher compression. mustan5069 made 530 at the tire on a 302 with the holley sytemax II kit and a s-trim with 6.87 and 2.95 pulley at 6,000 and 13 psi.

Those are some serious numbers! Definately go with the water/meth. system! Post some 1/4 mile ETs when you get a chance!

BECAREFUL!!!!!! I had a stock block with just under 500hp.

OUCH!! That must have made a dent in the pavement! -In fact after the first pull at the dyno this spring, my tuner looked at me and said " Umm, what block did you say you had here?" Then went on to tell me about the stock ones signing off at or before 500.

I was coming out of the burnout box at Milan. The car made a big bang then died. For some reason I thought it was an axle shaft or driveshaft. The starter ran over and told me not to refire the car and pointed to the hood.
I pushed it off the track and popped the hood. When I did noticed the belt was shreaded. I thought "Hell I can throw another belt on and get home". The only problem was my balancer was laying on the core support "OUCH".
Now I have a Dart Block with all the goodies.

I don't mean to hijack the thread but I would like to ask what clutch set-ups are used for 500+ rwhp? Does anyone use an 11'' set-up.

I smoked my CenterForce Dual friction. I went with a Spec Stage 5. Its grabby on the street -takes some getting used to, and once in a while it does get you at the light. I was going to go with a stage 5 pressure plate with a stage 3 or 4 disk, but there was a wait, so I went 5 all the way. Its the ticket at the track when the slicks are on though.
-
A SPEC stage 3 held up real well in my Real Street car. It looked like brand new when I took it out.
-
Spec 3 as well in mine and a RAM 900 Clutch Disk I got from RS NOVI worked well with my SPEC pressure plate in my setup too.

Hey 93GT, I was just wondering with the spec stage 5, do you get anykind of low rpm vibrations with that disk? I have the stage 4 in my car now and my car has a low rpm ,high load vibration in 4th gear almost like if you put a car in the wrong gear at a slow speed. I just bought Chris's stage 3 because the stage 3 disk has springs in it and figured this would dampen the vibration. I know the 4 and 5 dont have springs in the disk and I figured this was the cause.
oops sorry i don't mean to hijack your thread.

I use a Mcloud Revlock and it works great!
-
I guess my real question is, Do the springs in the clutch disk actually dampen vibration? I was wondering if you noticed an increase when you put the stage 5 in?
