247.6 rwhp 298.2 rwtq with mods below
i used a calculator by r.a.c.e systems that converted to flywheel #'s 285fwhp and 374fwtq

i was hoping for some number around 250, It turned out pretty well, a/f stayed right in the good range ending at 12.8

on a side note my friends 00' police interceptor with a k&n fipk and diablo chip hit 226

wait so you got 248/298 from CAI, tune and a midpipe and catback? And you think you have 374tq at the flywheel? I'm thinking not.

Mach's are stock 335 flywheel torque (possibly under-rated), and your not even close to Mach numbers with those mods.

At least it's more erect and not floppy anymore.

I hope that 374tq is a typo error.

numbers are pretty strong for the mods you have. Don't rely on your "calculator"... find a good N/A formula and do the math yourself. The formula does change depending on the HP put down and how it's put down.

Mine were about the same with a K&N, Pro-Chamber, and flows. Temprature had a lot to do with your numbers too though. I'd like to see the graph with the A/F and Temp on the sheet.

Looks like the drive train loss for an automatic trans was used for a manual. 375.09 FlyWheel torque with 20.5% drive train power loss is 298.2 at the rear wheels. Simple Math. The real question is 20.5% loss for a manual trans? While 284.6 FWHP with 13% drive train power loss is 247.6 at the rear wheels.

if my hp all in one were working as it should i would scan the sheet, it was like 24 outside but this was in a shop with only the back door behind the car open, no fans or anything maybe 45 inside. i'm kinda not too sure about the calculator either, download it and play with it and see what happens

45 is a low enough temp to give a few extra ponies over the average Dyno sheet. I think it's safe to say most people Dyno at 60-80 degrees in the bay.

Also did you average al of your runs or did you pick the best run, or the best numbers from different runs (yes some people do this)?

I think the most accurate way is to average your HP and TQ numbers from all 3 (or more) runs and use that as your base.

Power curve wise it won't make a difference since you'll see where the gains are.

i got the average of 3 pulls, it was a just by chance event that i did it, a friend called me and asked if i wanted to come watch his pulls and they asked me if i wanted to strap it down before everyone left. It's a dynojet research brand if that's important. according to my graph peak hp was around 4800 rpm. i am rather pleased with the rwhp rwtq numbers.

Does the sheet say the number were SAE corrected? This would remove an temperature questions.

I downloaded the calculator and the defaults are 15% for stick and 20 % for Auto.
