Man u need a dyno with a stock TB to compare lol

Dyno numbers are worthless without a before run to compare to.

With that said, those are still higher numbers then what most put down with bolt ons.

where is the graph? what dyno did u use?

03CLSMT

it was a dyno jet

and I was getting a baseline bc im thinking about putting together a rear turbo kit... everyone here knows what i/h/e/pullies dyno around so i wanted to show you guys what it was with the tb.

I will have the graphs soon he called me and said he couldnt email them so i have to go back and pick them up when i get a chance... but the curves were very smooth surprisingly

the first pull was done in 4th and only did 257.8
the next two were done in 3rd and were about the same until 5.5k where the more aggressive cam came into play

"Dyno numbers are worthless without a before run to compare to." you have plenty of other 6spd dynos to compare do with just bolt ons ... I didnt have to share the results so maybe next time I dyno ill just keep it on another board or not show it at all bc people like you clearly dont appreciate the time

03CLSMT

and dont give me the every car is different ... maybe on the b series that was true but the j32 has dynod very consistently its not going to make a huge difference so you have an idea what the gains were

Its not that every car is different (btw, it is), but that every dyno is different. Temperatures skew numbers, humidity skews numbers, fuel skews numbers. Dyno correction software has come a long way, but I guarantee you wont get the same numbers on a DynoJet in NY as you would in Florida. Hell, you could hit the same dyno two days in a row and pull different numbers.

Your current numbers are nice, but theyre meaningless without a run from before you did the throttle body. But hey, judging by your attitude about this you clearly were looking for a pat on the back. So, congrats.

Have you dynoed anytime before this or was this your fisrt dyno ?
Either way now you have a baseline dyno

Great numbers you should post pics of your mod also

Without tuning ability the ECU will learn the new power band & adjust. Dyno again in 3 months & I bet it's lower.
What is your 1/4 mile time? Dyno's are only good for 2 things. Tuning, & power brag rights.
I dynoed 260/232....but couldn't get traction & couldn't get below 14.5.

03CLSMT

Fuzzy maybe i wasn't clear before, but the TB has been on the car for at least 3months before the dyno. The ECU has had plenty of time to adjust I drive and hour to work everyday in the car too.



as far as your 1/4 mile... you should easily break into the 13s w 260 you just need more practice and maybe better tires...

but you can always use the trap speed for a good idea on what kind of power your making too.

Nice numbers. Are they SAE corrected?

3rd gear dyno runs will skew the results a bit. 4th is the closest to a 1:1 ratio, so the 3rd gear runs will be a bit higher. I guess as long as you do it consistently each time it's fine, but just keep that in mind. With 265whp in the CL-s, you should be trapping ~103.

And yes, every car is different. Every dyno is different as well. Dynojet's do a good job for comparison purposes, but they're not perfect, as Civic was saying. If you consistently go to the same dyno with the same method of correction (SAE), then your numbers will be comparable.

03CLSMT

thanks sonnick thats what i was going for...


BUUUUT I am thinking of selling the car because Im looking to upgrade to a 335i so if anyone is in the market for a CL S 6 speed NBP message me = ) asking only~ 6k

minor body work is needed on the passenger door and hood was keyed

AnthraciteTypeS

Yea let mikebike know in the next thread down lol. He's in the market for one

rp_guy

76mm is the largest TB available that uses the IACV right?

03CLSMT

still debating selling the car if anyone is interested give me a shout

Good luck with the sale! if I had an extra 6k laying around I would be all over it

At 265whp a 76mm tb seems overkill to me. You can get the same numbers or better with a bored stock tb or a 70 mm tb. You would need to be closer to 300whp to need a bigger tb.

03CLSMT

Ha if you think 76mm is overkill you should see the guys on j32 forums they put down crazy numbers with 80+ mm

03CLSMT

ps i did previously have a bored stock tb and i know the engine needed more air def felt the diff with the bigger tb... i was going to make bigger plenums for it too but kinda didnt get around to it

How is the throttle response off idle and in the mid-range?

brian6speed

iTrader: (5)

On a car with just bolt-ons then yes I think 76mm is overkill. There are plenty of people putting down more power than that with a bored stock tb or 70mm tb.
Your restrictions are elsewhere.

Now a stroked engine is a different story.

I read all the j series forums and more.

03CLSMT

throttle response and midrange is awesome, best mod ive done.

^id love to do this!

Id disagree to it being overkill. The biggest restriction is the intake mani, and exhaust manifold/header. Upgrade to the 09+ mani and port and polish the runners and the engine will gladly take 76+. Gasket match and port and polish the heads and it will want even more These heads have the capability to flow some serious cfm.
