So 30whp WITH intake ...

 

Yep. I want 260 whp!

 

Tune that little ***** ..

 

Congrats on the exellent #s and convincing me to purchase headers!

 

Stop posting and buy some ...

 

Its like an addiction! I must get SAFCII now... must get UDP installed... and timing advance! Arg! Damn the org for making me a ***** to my car!

 

I ordered some hotshot headers yesterday, and a UDP, im waiting for +20whp also with these mods. Wooooo.

 

nice results.....

those guys at turbotrix really know their stuff, mark came to d/fw and worked his magic on a few evos last weekend....i was really impressed with the numbers he pulled....and a really nice guy too...

i really need some headers too.....

 

"So 30whp WITH intake ..."

and catback.

 

Yes

And

Yes

 

i wonder if HotShot headers make similar gains with the same engine mods. any1 have comarison dynos with similar mods that care to share?

 

The Hotshots make between 25-29 hp untuned, and closer to 35 with AFR tuning.

 

whp or chp?

 

WHP.... few people around here really talk crank hp when discussing mods.

 

My bad

BTW, did you get the email with the runfiles?

 

Send it to me E55AMG2@gmail.com

 

I forwarded you what he sent me.... but it seems that he only has the run files for the 3rd gear pulls....

 

thank you sir

 

Here are the corrected #'s (for the 239whp STD run)

CF: SAE
Smoothing: 3

PeakHP: 227.13
PeakTQ: 225.86

 

Btw, Steven88 just pointed out to me that Runfile_003 is a 4th gear pull.... I got by the horizontal axis...

 

Just a general dyno question.... why did ya pick a smoothing factor of 3 and what are the "guidelines" for picking a smoothing factor?

Numbers seem low... does the AFR look pretty lean to you starting out?

 

Runfile 03 is a 4th gear pull, 01 is a 3rd gear pull


(dyslexia > me...fixed)

 

Oh yeah, that's what I meant, my bad...

 

Naw, you had it right.....01 is the 3rd gear pull.

 

3 gets rid of the spikes and doesnt hurt the peak #s. The difference between 3 and 5 is -.76hp/-.80tq (very minor). The range is about the same for 0 to 3 as well, but the powerband is very jagged looking at 0. So I picked 3 as a happy medium.

As for the AFR, yes it is lean before 4300. But, an SAFC/Emanage Ultimate/insertotherAFChere can fix it in a jiffy.

 

I had a chance to check them out on WINPEP and I was interested at what I saw. What is the DIN correction for?

 

 

Dynos here....

Power and TQ:

so are gen 2 headers not t3h r0xx0r?

 

Maybe after tuning... it'll vary from car to car... we'll reserve judgement till later.

 

IMHO- your car makes really bad power, try tuning it some- if that don't help sell your Stillen headers.

Proud owner of HS headers.

 

i think they are cattman gen 2s...

i order HS anyway...

 

DIN - Deutsches Institut für Normung

The German/Euro standard for rating power.

Blackbird: He has Cattman gen 2, and he's running leaner than all hell for the mods he has.

 

I would say a 30ish increase would qualify as substantial. For what it is worth my header money is now snow tire money but I will be able to provide before and after dynos when I get the headers tuned up.

 

HS headers and Gen1 Cattman were comparable. The gen 2s should have better mid range gains and slightly higher top end based on the dynoes done by cattman himself.

 

The HS seem better than these gen 2s in all respects

 

I know these are Cattman 2s :P Someone please send me both HS and Cattmans, I will install them both on a 3.5L and dyno them to see how much diff there really seems to be- and if the 400 dollar diff is worth it.

Sell em Stillen's.

 

Yeah I am definetly not as happy with the numbers after SAE correction. Going to have to tune.... soon

 

Its not worth the $400 difference, they dyno within 1hp of each other. Check the All Motor forum

 

dang thats really lean.
