Well to start off i have to thank George from J and G tuning along with J and J Performance for helping me with my dyno and nitrous needs. The dyno was a DynoJet 224 non load dyno with a temperature of 90 degrees and 8% humidity.

Now the setup

It is a 1999 Chevy Camaro SS M6.
100% bone stock short block (stock block, rods, pistons, rings, bearings, oil pump, and timing chain) that has 84000 miles on the clock.

Performance: T-rex cam, 243 stock valve size patriot heads, gold springs, trickflow 7.400 pushrods, comp R lifters, Tr6 plugs, 10.4 taylor wires, victor jr single plain non ported out of the box, wilson manifold carb nitrous plate, custom sheet metal intake elbow, NW 90mm tb, custom 4" pipe to run from the tb to slp lid (speed density tune), FLP long tubes from 2000 (old style) to custom 3"y to 4" exhaust all the way through the back with a flowmaster muffler (nice race one not the 40 series), m6 built by t56 rebuilds, 3" steel driveshaft, moser 9" with spool and 4.10 gears, full suspension, clutch is a ram powergrip HD ( that slipped three times on the dyno) and 27" tall et streets.

Nitrous: NOS 10 pound with hiflow valve to a 6an line to a NX nitrous sileniod to 3an line to plate kit and a 4an system with NOS fuel sileniod from the fuel rails. The jets used where 65 nitrous side and 38 fuel side which is a 125 shot (suppose to be anyways).

Now the dyno:

All motor with 29 degress of timing made 438.1 rear wheel horsepower at 6500 rpm and 391.3 rear wheel torque at 5200 rpm.

At 23 degrees of timing (the tuner pulled 6 degrees) and 1025 psi made 608.4 rear wheel horsepower at 6700 rpm and 634.6 rear wheel torque at 4600 rpm.

I know there will be people that probably say BS but that is okay with me, I was there along with three others and two guys who own the dyno. I just wanted to write this to help others see that the T-rex cam witha single plain loves nitrous.

Long live the T-rex cam

If people want dyno graphs or pics of the motor or car let me know and I can email them, have to wait to fet to a scanner. Just for the record, my tuner is the main tuner for Haddad motorsports and is a complete legit tuner.

 

very nice...

 

why dont you shot 150hp or 200hp ?

 

If thats a bone stock shorblock its 346ci

 

Just fyi a .065 nitrous jet would be about 162 at the tire.

 

fixxed the 347 sorry, really is a 346 and i used the jets from the instructions that NOS sent me.

 

Hey Charles!

I looked up some calculators and it comes up as a 160-165 shot, as mentioned. Either way, very impressive for your setup. Glad I was able to help you out, we will get your new setup dailed in when it is ready.

When I hit the nitrous, it hit hard and rev'ed to 6500 quickly. The nitrous passes were started from ~3000, no need to start any lower since the car won't see less then that at the track.

 

thanks george, for some reason the jets are written down in the instructions and holley.com as a 125 shot, but the 160 makes more sense.

if this motor saw that power i cant wait for the new 6.6 on nitrous.

 

Dosent Sound Unbelievble ... Sounds Right About Where I Ill Be When I Hit The Dyno

 

big cam, good nitrous combo = power. i beleive it. most should.

 

wow i was expecting people to say that a stock short block could not do 600 rwhp but i guess not. i have a feeling it will last for about 10 passes until boom.

 

Good numbers.

 

Very believable. Congrats on the strong numbers. Glad to see you pulled timing for that size shot. Your ringlands will thank you.

 

very believable. thats almost exactly what mine made with heads/ cam and a bottle. but i made a bit more on motor so you got a nice gain from your shot

 

Very impressive results man....congrats

peace

 

trmin8r made 600+hp on nitrous for over 2 years... he would drive the sh*t out of that car the whole time too

 

Yep it will last a while, just dont get greedy. I did then BOOM.

 

Congrats man awesome numbers.

how much RPM are you spinning the engine with the stock timing chain??

 

Nice! Now I want to spray my TRex.

 

lol motor will pop very soon.
