To The Top

Anyone else making BIG power on 91 octane?

Now's the time to fess up; don't be bashful; step out of the closet; post those big 91 numbers here for all to see...

 

i have a 50trim on an Evo VI...will post some numbers in January..as I am having everything installed...GSC S1 cams, GSC Single Springs and Retainers, AEM Cam Gears, FIC 850's, ARP Studs, Fujita Intake, Walbro 255, Exedy Twin Disk SD clutch, 3" TBE, Evo VIII IC, Custom SS IC pipes, Ralliart Thermostat, Ralliart Strut Bars (Front & Rear), Zacklee Cam Gear Cover, and possibly...not quite 100% but maybe a DNP manifold, since I am running an SFP manifold and they are no longer around.

 

oh and in the Dominican Republic....our best gas is about 89 and with some toluene, we should be looking at 91 octane...this will be for our street map...race gas will be another tune.

 

Alan678 keeps it real.

 

We have a bunch of cars whether DSM's or Evo's that run on our pump 91 out here in Cali.

Everything from 300 to over 400 on a Mustang Dyno.

My car w/ a very conservative tune made around 340-350 as the car mainly sees 118 now with fewer and fewer trips on the street.

We have another blue Evo9 that put down 370ish to 400 on our dyno sorry can't remember the exact #'s off the top of my head.

We both have 35r's.


Here's a link to a DSM we did recently:

To The Top

Thought I'd bring this one back to the top. Anyone else making power on 91 oct?

I'd think there would be a bunch. Arizona, Nevada, and California all have the same lousy 91 oct and, the Tri-State area has a number of tuner shops that are no stranger to EVOs - Mynes, Gruppe-S, Vishnu, Vivid, WORKS, Tuning Technologies, Harman Motive, Speed Element, Full Function Technology, GST Motorsports, Downforce, Road Race Engineering, - and I'm sure there are many others.

So, let's see those 91 oct tunes !!! Maybe some of these shops could post up examples of their best efforts tunning on 91 only !!!

 

WOT will have one of the higher stockish turbos on 91, but he doesn't go around bragging about numbers...

 

I made 450whp with a 35R on 91 octane. I'm running on cosworth 272's as well.

 

91 octane is a crime!

 

Can Meth be included??

 

^ Im sorry buddy your sig is nothing to be proud of with meth.

 

Here's the highest pump gas 91 oct car I've tuned.

specs.

EVO8 05'
2.3 SE stroker
ported head
AEM EMS
1000 cc RC inj
FR/SE big GT30R 60 lbs compressor

This is about 460 whp on a dynojet.

 

Darn..

I didn't know there was so many 8s with just TBE, Meth, and Headers making 350+whp... my bad..

 

With forged parts you might make extra HP from all the knock occurring with 91 octane
