Ray's s15 specs

[raytsang]

Thats very thru... i should not be maxing out, but that is if i was running normal petrol...
but im not im running E85 (Bio Etanol) which is 104 octane .

problem with E85 is it uses up to 1/3 more fuel then normal petrol so flow thru my injectors are maxing out. thats why I have to use 850cc so wont max out. as for the AFM think its just a leak in my FMIC thats causing it to near max out.

Fresh New Readings of the dyno.
was in a RR'day today, was on the Dyno Pack Hub Dynos. down in TDP.

got some nice fiqures.

381.9hp @ Hub
429.7hp @ Fly
409.3lbft @ fly

running 1.2bar boost
but it was creeping near 1.4 bar at redline. AFR was safe as it was map for it.

Well happy with the result. first dyno reading since the 850cc injectors went in and remapped.

just read the entire thread... wow! this is a stunning car, the missus was looking over my shoulder and her response? "dont even think about it, buster!" the thing is... how the hell do you control the power? i just bought my '15 and im probs only running 270-280 at the fly, but it wants to chuck itself into every hedge and garden on every bend! ok i know that i got crappy tyres atm but even so.... (i got tein coilies on too)

ah man - why is e85 like gods piss to get hold of round my way another great result matey - well done

Always good to see updates on your stunner Ray...


Those power and boost curves look very smooth - excellent mapping and I also use Dynapack hub dynos @ WGT in Middlewich

thanks guys for the comments.

Hey man , just saw your 750cc injectors were running out at that power ? thats pretty strange, they should be good till 280kw - 300kw atw depending on fuel pressure? My Tomei 740cc injectors are barely hitting 35% duty cycle at 10psi and thats only putting out 180kw/244hp atw, and on 14psi it makes 208kw/282hp atw on 95 ron and with a T28bb turbo, and the tuning is on a daughter board lol. Do you guys have Link G4 Storms over there? But anyway great work on your S15.

hes running E85 thats why he maxed out the 750's ya need more E85 than petrol.

 

[raytsang]

As Sniffy Says..
She's not running on petrol..

It's on Ethanol (AKA E85)
Ethanol Burns with a different Air/Fuel Ratio... Alot more fuel...

Advantages of running E85 is i can advance my inigition timing and get more power out of it. cause its rated at a much higher octane, 104 if i remember correctly.

another plus is the fuel is alot cheaper the pertol. currently 97.9cent /litre

 

[sniffy]

and dont forget ray ya get very low knock readings compared to petrol.

 

[raytsang]

havent been doing a whole lot on the car but here is next plan...
4.1:1 final drive

2 way diff (ATS Metal)

Just have to order some new bearing oil seals and some fresh diff oil...

 

[raytsang]

just did the maths it actually a 4.08:1 final drift much better then the 3.6:1 standard s15 ratios.... more torque and acceleration here i come..

 

[Trial_S15]

Very nice ray :thumbs: Will it all be done before the trackday?

 

[raytsang]

very hard to say... im getting prices for rebuilt so see how long it takes to get the parts in, was orginally stiv getting the stuff for me but hes finding it hard to source the parts.

 

[Trial_S15]

That's a bit of a pain but sure there'll be more track days.....

 

[LuPix_S15]

Awesome!!! Lemme know how it feels once it's on mate and I'll be looking at the same upgrade with similar ratio woo!!!


How does 2 way diffs handle out on track... I know people love them for drifting but what about grip racing like trackdays etc??
