Highest Boost on E85
 

Hi Guys

Looking to see what is the largest amount of Boost you guys have pushed through a Rotary on E85.
I tuned a 13B the other day to 38psi on E85 with no Knock. (Didn't put any more cause we ran out of Pump)
Mixtures where at 11.8. Had 8 degrees of timing.
Car made 680rwhp
Let us know what you have done.

Not sure about boost levels but with a 2650lbs 1st gen with a clutch assist trans it ran 9.3s at 153mph. That puts the HP over 700 easy.

AFR 10.4 timing around 10

What did the fuel system consist of? Also what kind of turbo were you guys using? :)

We make our own versions of the Bosch 044 that flow a fair bit more . It had 2 of them.
4 X 2000cc EV14 and GTX4202.

Engine was an unknown bridgeort with power seals (As with any power seals engine came to us hard to start).
So probably could have made much more if engine was descent with good seals in it.

Also when i mentioned 11.8 this was using Gasoline AFR conversion(AFR meter was set up as if i was tuning normal pump gas).

My wideband is on gas fuel also

I helped tune a friends car recently - semi-PP REW, Typhoon intake, 83FMW 400SX, Link Xtreme+ ecu, inductive ignition, E85, 890rwhp at 30psi from memory. Had to stop there because the the tyres wouldn't hold any more power. I assume it'll do 1000hp on more boost, or close to it anyway.

Typhoon intake provide much benefit over factory manifolds JZG?

I couldn't actually tell you Omar. The whole combination is new to me so I have nothing to compare it to. But you'd have to assume the typhoon works better than the stock intake..

This is Awesome I'M Building a very similar set-up. Was the Intake Cosmo Size? Also How many Injectors? Was this a standard wheel, billet, or Batmo-wheel? My goal is 1000 whp out of the car. Seeing you do this is very comforting to know I'm close to the goal.

Just thought I would update this.

Did a tune on my rx7 at 40psi and so far its holding together.
Will be gunning for a little more in the next few weeks when I have a bit more time.

type of port and turbo?

street port
gt4202

assuming about 700whp?

Interested how the engine held up with 40psi.

Who needs race fuel with e85 readily available these days
