Horsepower

+1.. I believe you as well (no money) but I believe 227 is the actual result, not 262. Whenever you get somebody do dyno conversions from one to another, you're factoring in assumptions. I mean if it's TS that did the conversion, they're at fault here.. Still, 227 is a pretty good number given that this is a stock block with few bolt-ons..

Btw, take a look at autoblog.com today. They posted an article on a dynoed GT-R.. It's a pure example to what dynos are capable and what they're not.. The power results for the test were all within .5-1.5 hp difference but out of 3 pulls, the first and last got the same torque while the second one got 10-15 lbft more.. Dyno results will give you a good idea if you do mod comparison at the same day or informing you on around what your actual power levels are BUT they're not reliable metering devices.
 
WynFlow reads low. It is a software conversion, not TS's.
Will's got good power . . most likely from the Tune & Header mod in combo with the others . . TBS :smile:

It's still based on assumptions Dave. It looks like it assumes the actual hp at the wheels are %15 higher than what is read. Is that a proven fact for all times, all cars? I agree Will has good power and I believe his power is definitely more than almost all of us NA 35ers. I just don't think it's 260ish at the wheels though.. You can't gain 50-60 hp from intake (cai+spacer), headers, exhaust and a tune. If that was true, you'd see 280-300 hp NA 350Zs with simple mods all over my350z.com. There's just a handful and they have cams..

One more thing: Your dyno results, also from TS shows 238 at the wheels after the tune. You are RWD as well and the only difference between you and will is basically headers & pulley right? So are we saying headers & the pulley adds 22 hp? Not likely really..
 
bro, I in no way meant I didn't believe you, honestly, was joking because that's just been a running joke from you of how some guy is so twisted that he accused you of that, still think that's funny :tongue: I'm sure your dyno reading did show what you say it shows, never thought or ment to suggest otherwise...

I don't doubt that a dyno could show an end result of 262, especially when your factoring in conversions, not for a minute, I'm just more saying what it is that that really means... if another stock fx ran on the dyno & pulled a 204 right after yours same day same conditions, & then yours went back on & pulled a 260+ again, then were talking about more apples to apples, but a dyno reading by itself & with nothing to directly compare & calibrate too just isn't set in stone as being anything absolute & concrete

dyno readings are relative to other runs on the same dyno & that's it, pretty acurate to itself really, but dyno to dyno are not expected to be on the same scale as there really not on the same scale... the scale of a dyno is only relative to itself, actual #'s are for reference & not direct comparisons, unlike other types of performance measurements that are more directly comperable, like 1/4 mile, 0-60 etc, assuming there measured with certified methods & equiptment, don't know if I've ever heard of a certified dyno, calibration is relative & not absolute when it comes to dyno's...
 
I've done 4 dyno's so far. First was 246 with Header, Plenum Spacer, and exhaust.
The second dyno was at TS at 330 conversion to Dynojet. I lost 30 horses after my fifth run due to transmission oil temp.

my 3rd run was with the same machine as my first. I did this to get the true value of what I've gained with the supercharger. It was a disappointing 286.

and my last one was on a similar machine at Shawn Church's at 340. I did 2 runs and they where both Identical except for the RPM which was a few revolutions apart.

I think dyno has a lot to do with environmental conditions as well. I'm sure a lot of you have noticed your newly gained power over the past few weeks due to colder air.

Apparently yes . . other than that, two other differences were, Will's run was on a cooler day than mine by 'bout 15 degreez (I remember that), also I had way less miles, so it could be that his engine is ripe & ready, & mine was not fully broken yet (I know that one is reaching a bit)
Anyway, he did a 15.7, & that says he's got some power.
