well i noticed that my car hasnt been running up to par lately. especially after a run in with a near stock auto 02 z28 and losing. you can see my mods in my sig. well i didn't get to go with my car to the dyno, i am sick, but my brother called every half hour giving me reports. the first run after adding 5% fuel it only had 315whp. WTF? that's pathetic considering I'm full exhaust and cammed. no ****** wonder i cant run with a near stock Z28, that's only 10 hp over what a stock ls1 runs. well any how he got my baby up to 362whp 370wtrq. but he even admitted in his experience with my mods he was fully expecting over 400 to the wheels. but this is the odd thing, he said my DR's were killing some power. he said that on his c5 that he personally saw a 30-40 hp difference between DR's and stockers. has anyone else noticed that. if its true i damn sure wish i had put my stockers back on before sending it over. but oh well she feels a ton better and numbers aren't everything. but boy do i wish i hadn't run my ****** mouth so much about my car now.

ps he also said he wanted me to do a compression check, just to make sure my valves are seated because i told him i was having trouble when i reassembled my heads after getting the valve job done, and i think maybe the place that did the valve job F-ed up, i am damn sure never going to them, and you know who you are if your reading this

Are the heads stock 243's? and the car an auto? If so i don't think that's too far off with a 12 bolt. 30-40hp extra with stockers vs. DR's is bullshit though.

yes stock 243's and no its a m6. damn though i read a ton of people on here pushing 400+ with nothing but cam lid and headers. oh well i like i said numbers aren't everything.
oh and is it normal to peak at like 55-5600. i thought these were performance motors, my the early peak?

see if you can get the graph. a tr224 should peak 62-6400rpm could be valve float. stock valve springs?

Where did you get dynoed/tuned?

i say you should be around 420 to 430 rwhp with the mods you have. beside compression test, check the heads and make sure the valves are seated well and opening and closing well.

your not going to be over 400 rwhp with that cam and heads with that rear end
i think you are little lower then what i would expect to see though but not tons
since u have the ls6 intake stock: id suggest at least a ported tb and u/d pulley

IMO...I don't think 420 to 430 rwhp is normal for a M6 with 12 bolt with a 224 cam...that is a small cam especially with stock 243s. He is maybe missing 20-30 rwhp considering drivetrain loss from the moser.

My A4 was a low dyno and with H/C/Fast made 393rwhp w/224 and Patriot heads. He is basically like an LS6 cam only.

Cam only LS6's make that on the daily...

Abdullah

iTrader: (2)

i thought he had a Fast intake. also you are correct the cam is a little small.

If you are peaking around 5500 rpm it sounds like your cam could be advanced 6-8 degrees. Did you degree your cam when you installed it? Sounds like it needs to be checked.

Whats your graph look like? I made 422/402 with the same type of cam and untouched 243's, through 10 bolt but pushing 17x11 steamrollers. Your 12 bolt shouldn't be worth 60hp and 30 tq.

How bout answering this? ^^^

say what? i think you've got it backwards.

if the car is peaking that early i'd def look at the valvetrain first. i'd start with checking the springs (as already mentioned, valve float) and then check the cam timing. something is off, that is a couple hundred rpm over the stock cam's peak. with those heads and a tr224 i'd guess 415-420whp through that t56 and 12 bolt.

i have the same setup 224cam and unported 243s i put down 383hp 372 tq but this was a stalled auto. you should at least be 400-410.

Dyno #'s don't mean ****. It's all about trap speed. Trap speed is way more accurate when it come to horsepower.

My car made 367 hp 377 ft lb on a mustang dyno thru an auto with 3500 tci stall and 2.73s in the rear with full exhaust, ls6 intake,stock 241s, and a Thunder Racing Raptor cam 236/242 617/613 111+2 109 IC. The Car pulls incredibly hard on the street cant wait to get some track #s when i install 3.73s. Dyno #s i hear are not all that.

Y2KblueZ-28

Dont feel bad those are pretty good #s for that setup.
