Default 402 LS2 535rwhp/490rwtq

Was run on Dynojet 248

Setup as follows:

11.4:1 Compression
TFS 235cc heads ported by TEA
247/251 .624/.624 112LSA CAM
FAST 92/92
1 7/8" Headers into 4" single exit exhaust
T56
In a Mazda RX7


Made 499rwhp/446rwrq on a Mustang Dyno couple months back. Nothing major changed.


On my first run which isn't shown, car either spun or clutch slipped. I had paint off the dyno rollers on my tires though. 2nd run did too a little as you can see.







Here's a run on the dyno. Disregard the title.

Thanks for the feedback guys!

I went to the track last year on street tires and about 460rwhp. Was spinning all the way down the track. Best was a 12.7@124mph lol



Here's a pic from a photo shoot

mamofied fast 102, mamofied afr's (already have afr 205's milled to 59cc), custom spec'd cam, revamping exhaust, one hell of a tune, and a few things to free hp UDP, EWP if needed. figure hell if 346 guys can push out 520 whp on a 10 bolt then i can do 500 with a 12 bolt.

OP ... looks much better than the twin turbo rotary it replaced and I love the blue! Don't you love the torque ... there is nothing better than 500 ft-lbs at the rear wheels!

taman86 .... you may get 500 rwhp, but not 500rwtq without the cubes unless you put it on the bottle or boost.

Yep, I am chasing traction issues right now. As soon as these stock shocks come off, I should be good to go ... Strange DA coilovers are on the way.

There is no hope for traction issues on street for me though.

Damn, I was thinking my dyno was that far off till you said it was uncorrected.I'll never print uncorrected.

What the corrected number to give me an idea?

Never got any corrected numbers from them. This was just a local dyno day I decided to show up to. I made the most power out of 20 cars there.

If you were to go to an actual shop that used SAE correction you would probably get right around 500rwhp which is believable with the topend you have.

I am just curious about your opinion .... why is 500 rwhp so "believable with the topend [he] has"?

I am making that power (SAE corrected) with a smaller head (bore & intake runner volume) (both CNC'd, but his ported), smaller valves, smaller tube headers, smaller cam, smaller intake and smaller throttle body.
