its a 01 trans am 6 spd. what i have done
eps 226 234 cam
tfs 215 heads
arh long tube headders 1/78
catted arh y pipe
have the 42lb injectors not on yet
ls2 t chain
hi vol oil pump
3 inch slp cat back
racetronix fuel pump and harness

im happy i at least made 405rwp. i was told that this cam would make in the
450rwhp range so i was expecting a little morelike 430 ish rwhp.
what do you guys think is there more in this car. or is it right on for the setup i have.

Thats very low for a 6speed and trickflows, it should be closer to the 450 you expected, i just did 404/385 with unported 5.3 truck heads through a 4.11 35spline 9" rear that robs about 15hp and 10 torque compared to a stock 10 bolt rear. Id check compression, your about 50hp low or thats a VERY stingy dyno. How do other heads/cam ls1's do there?

im using stock ls6 intake tb and maf with slp lid. rest of my car is stock. my trick flows are at 64cc. we had a problem with the clutch after 3 or 4 pull clutch pedal was comong up very slow. had to let it cool down to do last pass. do you guys think its the clutch holdingmy car back it has 77000 km on it and its stock. should this be the first thing i take care of. or do you guys think its not th issue. thanks for your guys help.

tunner saaid the tb is holding me back and clutch. what do you guys think.

Could be, if the clutch isnt fully engaged and its slipping it wont put the power down. Throttlebody wont hold you back THAT much, maybe 5-10hp tops. And then again with a FAST 92 or 102 setup should be more like 460-470 with all your other top notch stuff you got. Id try a new clutch and check compression and redyno it.

Another thing i dont like is your cam choice. Trickflows have EXCELLENT exhaust flow and like cams with a closer duration. Your 226/234 would be better being something like 232/234 with these heads.

That cam is better suited for a GM cast head where they have great intake cfm but dont flow well out of the exhaust side

I think it is time to save for the Fast intake with a matching throttle body. I think that stuff is killing you. I dynoed the same as you back in the day, except I had stock heads, and crappy MAC midlength headers. But I had the Fast 90/90 combo.

I agree a FAST would help but even with an ls6 intake a setup like this usually does way higher. Its dynoing like it has a 97-00 ls1 intake

Also you probably did this but did you get the 7.5" length pushrods and roller rockers that trickflow's require/recommend? If you have stock length 7.4" you wont be getting enough valve lift

Those numbers seem very low for your setup and you tb and intake isn't the main culprit imo, i'd find out whats wrong before i'd buy more go fast parts.

spiro27

I have yells terra 1.7 roller rockers. The pushrods were. 7 something I will check it out and tell you guys. If I had low compression wouldent the runner know or wouldent the car make less power. If I did the fast 92 and 92 tb. A under drive crank pully. Would I be at 450rwhp.

spiro27

Should I start off by doing the clutch what do you guys think.

Check compression first to check if any cylinders are low and then do a clutch, sounds like you need one reguardless, and if you had low compression in say 1 cylinder it wouldnt be that noticeable especially being your cammed the car lopes anyway and low on compression would probably put you where you are at if it wasnt that bad. Underdrive pulley is worth about 5-10hp and intake about 20hp MAX on a stock cube ls1. But you seem to have more going then that. Like the guy above said i wouldnt spend more money on go fast stuff until you get it "fixed" if you got low compression or something wrong in the valvetrain an intake isnt gonna help.

ajrothm

I agree....

Most H/C cam LS1 cars have been making 430+ rwhp for damn near 10-12 years with a stock LS6 intake and stock TB...even with a stock balancer...And that was using archaic/tiny 224* single pattern cams..

I would expect a MINIMUM of 430 rwhp with any head/cam combo and an M6.
Id be looking for another dyno as well as doing a compression/leak down test.

garygnu

that cam works great with TFS heads.get a better clutch ,and you need a fast intake.your exhaust with cats are holding you back also.if you find any low compression do a ls383 short block .

spiro27

i will check for compression soon. i have tfs 21407500 pushrods says 6-7.50x 5/16 on the
package. when we were dynoing it it never stoped making power.

Bet its because you still are running stock injectors...

spiro27

Running 42lb racetronics injectors.

obviously a low number.
