Is This Reasonable Or Not?

[sdc01]

Hi guys

just had fitted the following: 3582r 63 rear (internal gate)tomei 740 inj, viper ecu, bosch 044... boost 18 pound. It pulled 250rwkw on the dyno. Does this sound about right or not?

Regards

no, who tuned it?

i was expecting around 280 at the wheels.... is it cause of the small rear housing or no fuel reg??

R33 with 3582r (i will check housing size 2moro for you) 18psi but with 264 cams.

Fuel reg on a r33 is good for high 300rwkw so your reg is not the issue.

if not what would be an expected figure and is 18pound to conservative?

[Adriano]

18 psi on a conservative tune will see over 300rwkw

[sdc01]

Thanks Adriano. Thats what i was expecting as well. I kinda got the impression that it was all done in a bit of a hurry..... guess I'll be booking it in with a decent tuner shortly.

got same setup, apart from I got the 0.82 A/R. I have a VERY conservative tune (f#$k all timing, and running rich, knock doesnt go over 15) and I made 312 rwkw at 17 PSI.

I suggest you go see another tuner.

[sdc01]

Yeah, thanks for that. Doesnt matter what gear youre running , it all comes down to a proper tune doesn't it? Funny thing is this guy has one of the best reputations in Melbourne and the results to prove it, but i highly doubt that he tuned my car. Anyway i will post both dynos once i get it retuned elsewhere.

well you'd expect that the smaller rear and internal gate might choke it up a bit. I think high 200's would be more on the mark. who knows, but good luck with the next tuner/tune.

[Turbz RB-25]

It's put in 4th gear so the tuner is able to tune it.

For example, you would not be able to tune a car in 1st gear because power just comes on way too quick.

Yes it does matter what gear you're in, 1st and 2nd gear will have much different power graphs compared to 4th gear.

Take it to another tuner to get a second opinion. Maybe something was wrong with the car (i.e. detonation) so the tuner had to pull timing out of it, hence the low power?

Maybe there's carbon build up in your engine causing pinging, or a hot spot on the piston.

Take it to another tuner, if he tells you he couldn't pull anything more than 250rwkw without it pinging of its tits, then somethings wrong with your car.

The fun and games begin.

[sdc01]

Yeah thats exactly what im going to do. He said everything was fine, that there werent any issues and was actually quite happy. Its not that i want more power, cause its fine the way it is. Its just that i believe that with this set up (barring any issues such as the ones you mentioned) the car should have pulled more than it did. As i said i really got the impression it was done in rush to get the car out of there, and im sure it wasnt tuned by Mark himself.. I'll be booking it in this week sometime elsewhere..just for peace of mind!

the 0.82 makes 300 easy the 0.63 does not.
