Hi guys,

My tuner just sent me these. What do you experts make of this?

My setup:

3.0 old style CTSC
GruppeM intake
Super Taitec C3 exhaust
AEM
550cc injectors
Walbro pump

9lb pulleys I'm guessing? Looks good to me. Stock headers or aftermarket?
 
I can't help but notice the pair of sweet aftermarket mufflers:)


Just out of curiosity, do you have any videos of the run? I'd like to hear the engine with an extensively muffled exhaust setup.
 
380 on a 3.0 with a 6lb pulley? That's very high. Like... 50 high... Idk what to think of it. Are these SAE corrected numbers?
 
Gents, Dyno corrections aside, FWIW I think with an EMS and better gas will give significant improvement on the low boost CTSC. These numbers are indicative of such.

I was curious on the IAT and Dimer seems to be running at about ~150-170F. This has room for cooling for even better numbers. If these can be brought down to 120-140F... HP will go up even higher and the car will run safer. This makes me excited for my F/IC, RDX, Meth, 7lb Autorotor setup.

I'm a firm believer in the low boost pulley. To me the extra 2lbs on the 9lb pulley is not worth the tradeoff. The low boost setup just needs to be made more efficient. $0.02
 
The scale for these charts is in PS for HP and NM for TQ, so his corrected peaks are 374whp and 277wtq, still great numbers for a 6lb CTSC but not as high as first glance may lead you to believe.

Ah, I was really confused how it was pushing that much torque! Still some very solid numbers for the setup!
 
I'm not sure but you see these high numbers because Dimer was measuring engine hp and NOT whp like you guys do in the US.
Pretty strong numbers though but also on the lean side as well. I'm at AFR 11.0 with my newer low-boost CTSC and have lower numbers of course but feel safer. Ok, I don't have that super-larger muffler in the back of my car. :D
 
Can you please tell my why 11.5-11.8 is a high AFR at max boost?

12.3 AFR WOT is the number to look at (see above). Everything above 12 is a little bit too lean for me. I guess that these numbers were taken with a wideband-sensor in a welded bung.
He only gets 11.5-11.8 between 7-8000 rpm which is ok. 12.3 is not.
Boost is about the same between 3000 and 8000 rpm with a low-boost CTSC.

I would rather be 11.5-11.8 the whole way vs 12.3 and with the AEM that should be an easy fix.
 
is 12.3 really unsafe with 98 octane and proper tuning? Mostly in the timing events?

I don't think 98 octane over there is equal to 98 here. 98 RON is closer to 93-94 for us.

Plus its a Dynapak which is going to read high to begin with.

+1

Different output numbers (whp versus bhp)
+
different gas octane declarations

a lot of misunderstanding and confusion. :)
 
Hi Dimer,

Very NICE results :smile: :smile:
Good to see that the car and engine are doing fine.
I do remember that exhaust though, it is extremely loud :biggrin:

Where exactly was this dyno made? Any possibility there to get all the raw data in a file there?
