Dyno Guesses & Bench Racing Forum - RWHP and 1/4 Mile Guesses?

I am doing a cam swap before the summer and am just wondering what type of numbers i should be expecting???

My planned setup:


Stock bottom end LS1
Futral's F13 Cam
P&P 243's
LS6 Intake
Pacesetter LT's w/ 3in Y dumped
P&P TB
EGR Delete

A4 w/ 3600 stall
Eaton Posi
4.10 gear

Subframe Connectors
LCA Relocation Brackets

What kind of numbers should i expect with a dynotune??? Also what kind of 1/4 times should i expect to enjoy with this setup??? I would like to run 11's if i can get the car to hook.

420+ easy high 11s depends how you come out and if you hook ect

I would be very pleased to see 420+ and run high 11's. Those numbers sound great to me.

Anyone else have guesses???

If it was my car, I'd hope for around 420 SAE on a Dynojet with that setup. A little more or less wouldn't surprise me. That's a good sized cam but the quality of the headwork will be a big determining factor.

Being a stalled auto won't help with the power but you should have no trouble with high 11's at an average track in average weather if you can hook and don't break the 10-bolt. Stalled autos tend to see quicker ET's with similar power/traps as manual cars.

My 02 Z28 made 408 rwhp SAE on a dynojet with 4.10s and the steeper geared MN12 T56. It was full weight (~3650 with me in it) and I ran 11.7 @ 117 at LVD in hot weather. Went down to Atco in cold weather and went 11.4's @ 121, but that's a great track in a killer DA. With your stalled auto and similar (or more) power, you should have no trouble matching my high 11-second slips if you can hook at a decent track.

The heads picked up 35 cfm from stock. They flowed 266 intake originally and went to 301 at .500 if i recall correctly.
