Here is a video of my recent Dyno pull, roughly 16-17 psi, 100 percent stock s5 6 port block, E85. T70 Borg Warner.

Final number, 400.6 whp on Dynodynamics. Very conservative timing, plan to go back next month and go up to 20 psi and more aggressive timing.

Nice. How many miles on the block?
Also what steps did you take to be able to run e85. As in prepping for corrosive properties.

 

Arent you afraid of cracking the rear plate? Impressive though.

 

It's all in the tune. If it has a good tune there's no worry about the rear plate cracking.

 

has anyone measured the s5 n/a plates? Do they have the same dowel pin casting thickness as the s5 turbo plates?

 

I picked up the motor locally for parts so the mileage is unknown. After compression testing it I decided to use it as is. Will the rear iron crack.. I don't know, I guess we will find out in time.

My fuel system consist of Twin Walbros, 1200cc/1600cc Injectors, a1000-6 regulator It is a parrallel setup with individual lines running from the tank.

 

Damn you have more ***** than me running that much power through a stock s5 na...

 

I am sure its been done many times before, likely at higher power levels than mine.

 

Also, the NA exhaust baffles are still in there.

 

Impressive! looks like I'll be able to hit my high comp turbo goal afterall

 

SO you really didnt take any precautions as to e85 corrosion. YOu just made sure you could move that much fluid. I would like to see that car on the streets with on board cam.=D

 

Yes, no precautions.

I have not run into any problems, some say that e85 is no more corrosive than gas, at least not enough to make a difference. A lot of e85 corrosion problems come from the fact that e85 is water soluble so it will absorb water and rust stuff out.

A side not, I am using Klotz Benol which is an alcohol compatible 2 stroke.

 

Your premixing the KLotz?

Thats why i steered away from e85. I currently premix.

 

Yes it is the worst part, adds about 40 cents to each gallon. I am currently looking for alternatitves.

 

better

 

I want to know this as well.

Arghx, I did use your rtek 9.7 rotor timing map and converted it to e6x with only a few minor tweaks, mostly in the split. I only had an hour on the dyno so I couldn't dip into the timing more, right now at the 16psi bar I have 10*adv, 11* split. Sure alot more power can be had with the timing, just ran out of time.

 

damn.
Might get better response with it off, but thats an impressive number for sure

 

I am sure it would help, but I wanted this setup to be a 100 percent NA block. Nothing is changed, only modification to the block is the oil return in the front cover.

Nice thing about it is If I ever sold the setup, everything would just bolt up to a s4 or s5 NA with limited modification.

 

yours would be a benchmark on how well a bone stock n/a block will handle power.
if its still running after 2 years, it just shows us how great the n/a block handles power.

 

I think it has a lot to do with the big turbo. A T6 Frame turbo wont see much boost untill 4000rpms plus. The rotary is vunerable to detonation in the 1,500 - 3,400 rpms range. on top of that the exhuats housing is more of a proper size for a rotary in my opinion delivering a lot of cool air.

Either way.. It iis an axample of what a proper setup Can do.

Thanks for sharing and i know it gives a lot of us hope.
.

 

So how is the response on this setup? I'd imagine pretty good w/ the high comp rotors, but then again is stock port and a T70 is so sabb snail....

 

response is not bad. If you were use to a stock turbo and jumped in this you would feel like it is really laggy, but you quickly learn to drive it a bit different and its not a problem. Basic thing is just keeping the rpms up. Shockingly it will open the wastegate in 1st right at the top.

 

That's amazing. I'll see if I can get measurements for the dowels for you.

 

nice man

 

PLEASE let us know when it blows up! I'm very interested in the longevity...

I'm just floored that you could make that power on an NA motor...
