SMSP, Who hopes Scott has a little sense of humor left after these past few days.

I wonder whose car that is

 

Looks good.

 

...uhm, me wonder why you did the test backwards?
Most tuners start modeing from stock and up

 

good numbers.. hopefully mine will be just as good

 

Yup your DC JDM 4-1/Stock exhaust is pretty dang close to what I got with my DC JDM 4-1/Comptech exhaust. Good stuff doing a comparison of the stock exhaust against a 2.5" exhaust to see what would have happened

Now Dave, where's your header?

 

I would like to see the same graph with your header on there as well....as I wait to cough up the $$$$$ for one soon.

 

Good stuff. Thanks Dave.

If anyone is interested, i'll have a few comparison graphs after the dyno next weekend (11/23-24):
1. current setup with stock exhaust vs. fujitsubo rm-01a both with stock ecu.
2. same as above (both exhausts) with kenji's p28

current setup - (j's intake, dc jdm, carsound 94066, 18 deg timing)

 

thanks

 

I'll have a similar comparison charts w/ 2 different exhaust & 2 different ECU's.

I think it'll be an interesting comparsion by itself and compare to Chris' comparo charts.

Ah so that's not a DC, the curve looks slightly stronger than my car was by a couple hp here and there. Pretty much the same though. Definitely looking forward to seeing a full SMSP system dynoed and maybe tuned.

 

~10 Peak WHP and ~5 WTQ. Not bad for minor Bolt-Ons.

Also, is this after tuning? Or Straight Bolt-Ons. Even minor Bolts-Ons benefit from tuning on a Dyno.

Suprdave

 

untuned....

 

pretty good gains

 

not bad at all? That is with just CAI?

 

sometimes I wonder if people read any words of the threads at all or just look at pictures?

Dave: did the car come in modified and go back to stock? the numbering of the runs made me curious then I saw Eric mentioned it too..

 

George: I dislike your new/old title

I still think "British Gent who is the Fizzle" would be better.. even compared to "British Gent who can not spell correctly"

Edit: Maybe just <FONT COLOR="blue">Grandpa </FONT><FONT COLOR="red">:FIZZLE:</FONT>

Is the "2.5" Exhaust" an SMSP exhaust?

 

Very interesting!!! Especially the (small) difference between stock exhaust and 2.5" exhaust......

 

Dave, any larger pictures of that dyno?

 

 

 

Wow. Good numbers and Nice gains from such little mods.

 

3 HP with the addition of an exhaust
