Dyno results, ONLY mod Nameless Downpipe. (Yes, I know, no baseline....) - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Sportsguy83 · 03-16-2013, 08:03 PM

DISCLAIMER: NO Baseline before Donwpipe mod exists.

So, I wanted to do a Dyno baseline before getting a FI kit soon. Unfortunately, I had no time to remove the Nameless Downpipe High Flow Cat and Helmholtz. 2.5", so the rest of the car is completely stock but this is with Nameless DP/OP combo.
See below.

Numbers look good considering it is a Mustang Dyno but really, there is no baseline. Max numbers were 175 WHP, 142 WTQ. IMHO I'd say the Downpipe makes anything from 5-12 WHP and 5-10 WTQ. Numbers were SAE corrected. Thoughts, opinions?

I'm really sorry for the crappy Dyno image.....

Mustang dyno should read lower than Dynojet, since you dyno more than most people's baseline with Dynojet I am thinking this mod probably gave you roughly 15-18whp. That's impressive, but I am curious how much it helps in the midrange.

I guess that to look at how the mid range is affected, a good starting point would be their original Dyno sheet. (I agree with you that the numbers look impressive, but stated in the OP 5-12 WHP gains to be ultraconservative and erring on the lower side).

Is it with the High Flow Catalytic Converter or not?

Yes, High Flow Cat and Helmholtz. 2.5" OP updated.

LeeMaster · 03-16-2013, 09:19 PM

that does it, my next mod is going to be Nameless Overpipe/frontpipe + highflow cat + helmozts

Very impressive figures, especially without a tune.
What a shame you can't do a baseline run then I could show MRT in Oz that exhaust mods can produce real power without a tune.

MRT
We have just about run out of brands and designs to test that will deliver real results.
So far we have seen exhaust that will generate "some" power over a stock zorst with stock ecu tune, but these gains are mainly due to removal of the two cats.

This is on stock air box? With oe filter??

You'll get at least those gains with a pump gas tune, and more like 25-30 whp with our e85 tune.

Just food for thought.. I totally understand wanting a full pipe set though. Bang for buck though, it's hard to touch the tune. Plus you get added features only software can provide (and updates!).

Yes, everything else in the car is bone stock.

(sound generator is removed and plugged, but that does not count as a mod).

I'll be getting this as my next piece to my exhaust, then the Nameless beast of a header. Thanks for the post David!

Huehuecoyotl · 03-16-2013, 11:34 PM

I think that's great then. +1 nameless is what i say, heck yah

I'm glad to finally see dyno results popping up

I want you to try an air filter drop in and tell me what happens, I have a drop in Perrin sitting for two weeks in a box in my garage. Im betting a trd or other drop in will help, too, I run one in wife's car on oe exhaust and she felt a difference.

Looks like she gonna get a helmholtz!

I am curious to know about filter. Wanna try it? I can send it to you at my expense, if you like it and you keep it I dunno slip me a $20 or buy me a few drinks. Lmk!

Congrats on the dyno results!

Looking at the results off the dynojet sheet... I made about the same with the motiv hfc and op. stock filter. I have a dyno sheet ill post when I get back home. After I got the tune it pulled 188hp. Oil temperatures were pretty high, considering I did a 4 hr drive to get it tuned...and I added a works drop in filter after that. I should be at about 190 now. Again ill post my dyno sheet later when I get home.

Was there a difference in sound with stock everything vs. the nameless downpipe w/ hemholtz?
