Re: LS swappers dyno results list
Afternoon All,
I was able to get the car on the dyno last night down in Victoria, TX. Mods to the car:
Junkyard LQ4 pullout - stock crank and rods
Aftermarket flat-top pistons
Junkyard 799 heads, ported by Katech, milled ~.020", valve job, BTR springs, trunion upgrade
Pat G Cam 231/238 .629"/.615" 112 +2
Stock LS6 intake and TB
Speed Engineering 1-7/8" headers
Walbro 255, 42# injectors
LS1 style T56, Monster LT-1 clutch, 3.73 gear rear
Hooker LS swap true dual exhaust
As for the numbers on a mustang dyno, best run:
Weather Corrected HP/TQ - 499/413
Actual Measured HP/TQ - 462/415

Re: LS swappers dyno results list
Cool, thanks. Got you added to the list.
I put you down for 449 RWHP because that's what the sheet says.

Re: LS swappers dyno results list
1982 Camaro Z28
5.3 aluminum block 58x (I think 2007-2009) machined and tweaked by a local shop ... nothing stock
Ported 243 heads
Custom cam
LS6 intake with ported LS1 throttle body
Pretty sure the original T10 (dyno pulls in 4th gear)
3.73 gears
Ram clutch and flywheel
Speed Engineering longtubes and single muffler
MS3 Pro drop-in harness and ECU tuned by Peter Florance (PFTuning.com) at Abacus Racing (Dynojet) in Virginia Beach
368/362 (last run, adding some timing up top after a long cool down) -- corrected 360/353
For fun, here is a comparison of the old L98 on the same dyno:
