Ok guys, we did the dyno today, it's my first time and it's the only dyno in Lebanon, i drove the car, the dyno is DYNOCOM type 4WD, the numbers are SAE, smoothing 4, outside temp is 67F, 4 runs done, the graph is the last 2 runs which i did on a different tune, all 4 runs are between 7-8 hp difference, all runs are on 4th gear(1:1 ratio), i put ice in my rear reservoir, fuel is 98 octane here which equal 93 octane in USA, the 2 tunes are Jerry mail tune sent before, mods in my sig.
i attached also a video of the garage, i couldn't take a video when the car is running on dyno cause i was driving.
i don't know about this type of dynos but i think it reads high, cause the garage owner after many cars running he find that the losses are 10% for crank hp/tq not 18%.
So guys don't be surprised yes the car made 428 whp and 431 wtq which he convert them to 471 crank hp and 474 crank tq.

Congrats Robert,good job

 

Impressive...

 

waiting your numbers Ali.

 

I hope i will do it tomorrow

 

WOW!!! Big Numbers for a C32!! Now you gotta give her a qtr mile run to see what she does. Very impressive #s.

 

ali i didn't know you were on here...that's awesome!

 

Unfortunately no 1/4 mile here!

 

Niiiice JOB!!

 

WOW those are some nice numbers, any videos of you on the dyno?

 

From Original Post

 

428whp no wonder you beat the e55 so easily in your videos. Congrats. I think that is the highest HP c32 to date.

 

I raced 2 days ago a friend E55 with 180mm pulley and tune, attached are 2 runs, first run he beat me about 3 cars at 400mile, the second run i think he was heat soaked he beat me only 1 car at 400 mile.

Awesome number, congrats!

 

Not to be a naysayer, but IMHO dynos are really only useful as a tool to evaluate the efficacy of modifications, or to check tuning and AFRs in a controlled environment... one single data point really doesn't give you much to go off of.

Anyone could strap onto a dyno, monkey with some of the settings and correction factors, and make 400+ whp. I'm not saying you (or your operator) did that, just that all dynos read different. For example, I notice at the bottom of the file, it estimates your engine HP at ~472. Using the accepted driveline loss of 18%, whp should be around 387. This particular dyno is claiming over 40 whp more than that.

If you had a stock baseline that made around 300 whp, and now are at 420+, then that's different. What we can tell from this one graph though, again IMHO, is that your HP and TQ curves look really solid. Assuming equally good AFRs and no pulled timing, your tune looks to be dialed in with your mods very nicely.

 

Sorry for my bad english,
but what you are saying is the same what i was explaining in my first post,
that this dyno reads high and the garage man after experience convert them by 10% only for losses(428*10%=471 crank pulley), so yes if you to consider them 387 whp for a lower dyno, it's right.
but what we are 100% sure that the car made 470 crank hp and 474 ft/lb crank tq!! from this little v6 3.2L. i am really impressed from those nb, i wasn't expecting those nb.
i only have 185pulley, tune, headers and cooling, all others are nothing, and remember i have no dyno tune, i have mail tune.
Btw i got an 80mm TB, i will install it, and i finished the install of my Zex 55-75 shot nitrous, maybe next week i'll try it and dyno it with nitrous.

 

Um......
Is it really safe to dyno your car when the rest of the country is in a uprising?

I say this bc all my american engineering friends have evacuated the place???

 

only part of the country is in uprising, he's in a complete different area.

 

Probably a good idea!!!

 

You gave him a damned good run, certainly wasn't a shellacking!!

 

You may be saying KaBoom with the ZEX and all those mods (hope its a wet shot).

 

There is nothing here in Lebanon to worry about, everything normal.

 

Jerry will take care of a tune specially for nitrous, sure it's a wet kit, but i think i'll do the TB first, retune, then finally n2o with tune.

 

Where did you obtain a TB and at what cost?? You sure it fits?

 

Fluid Motor Union was able to do it, so I'm sure he can figure it out. I know that the the tb from s600 is a 80mm, all he has to do is have is rear super charger housing ported and maybe have adapter welded on. I have one I plan on doing, but mine is a 82 and may even be an 85mm throttle body. I have an idea of how I want to make it fit, but it will involve having the rear super charger housing trimmed and ported so that it will give me enough space. Not sure, still thinking of ideas.

Robert, did you have a full exhaust done in addition to having your cats and resonator removed. How does the car sound now with long tube headers?
