So the car was running a bit off, so I took it to True Street and had them run it on the Dyno with WB plugged in - it turned out to be running extremely rich (10.2-10.8). Sean worked his magic, and with the EQ, MAF and VE all in check, I walked away happy. Guy knows his stuf....

very nice power for them heads...nice job on the setup...how does it run at the track?

 

I'd get a second opinion on the dyno because your current one is way too generous

 

Very cool setup and how much are the heads milled ? This car will eat For sure

 

Needs a driver mod, I'm sure - but I'll have some ET's up this weekend

3 Years ago and 500 miles away with the same setup it dyno'd 477x424

They're TSP's - Link

 

She's a stout one! Very nice!

 

we know what heads they are he asked how much they are milled...

 

Great numbers. Can't wait to see the track results.

 

Milled at 62 out the box last I heard

 

Nice numbers!

 

Those #'s are STD, so for apples/apples comparison sake you'd probably made 455'ish if the #'s were corrected/SAE. Still a stout setup especially through a 12 bolt which robs about 20hp.

 

Here's the SAE Chart - wasn't aware everyone posted SAE here



467rwhp | 414rwtq

 

Well built setup will make large power your car is living proof!

 

Nice hp AND torque outta this H/C combo!! Budget heads that delivers.

 

that seems more inline but still great numbers

 

Thanks - I eventually will be looking to port the FAST and I'm thinking about re-doing the exhaust to find some more power (True Duals or maybe a 4" merge) as well as doing a UDP and a EWP but haven't decided if I want to go that route.

 

Def port the Fast. It will be good for another 10-15 HP on combo. I picked up some good power with my 92.

 

That's a mighty generous dyno, so with some aftermarket heads and things like udp/ewp you could be pushing 500rwhp thru a 346...damn.

 

Ended up busting a trans-mount at the track last night. No ETs as of yet

 

Awesome numbers!! Cant wait to see what she does at the track!!
