Nems NA to TT conversion, with an added suprise ;)

Ok well i'm fairly pissed off, filled the car up with E85 and for some reason my ethanol compensation maps weren't working like before, no matter what value i put it would read way lean. So i decided for now i'll tune it off the primary fuel and timing maps.

AFR is at 12.0-12.3

Timing is at 25* up top

Had issues with two eboost2 units(suspect wiring in the car) so i was stuck on 6.8PSI the whole night. All i'll say is from a standing start first and second gear was like being on ice.

 

problem after problem. getting sick of it yet?

 

I was sick of it before i started haha. Either way my mbc is here and I'll see if i have time to up the boost tonight.

 

Ran 20psi last night, car is an animal considering its still on factory dumps. Only problem is my hardpipes on the passenger tb doesnt like staying on. Need to find a way to secure the pipework better.

 

Ok well dodgy fix on pipes has been done but it looks like i need new couplers on that side. 3RD gear the car really starts moving and even from low RPM in that gear it feels great. For anyone wondering if going to E85 is worth it on factory turbos i can tell you YES IT IS! Worth every penny and i'm honestly probably never going to run 98RON again. The zed is faster now on 12PSI than it was on 17 on 98ron. Going to try cram 22-23PSI down its throat tomorrow night if i can keep the piping together.


Really keen to see how it runs on sunday, if i can get a clean run that is.

 

Ready for tomorrow, Wish me luck!

 

Good luck !

11's ?


.

 

I'd be happy with a low 12 considering its a 5spd, an 11 is the ultimate goal though. Got a couple PSI more into her tonight and she goes like a rocket for factory turbos, we'll see how we go

 

Good luck! Make sure you have fun :br:

 

12.60 @ 106 is my guess

I know ultimately you will go
Much quicker though

 

Snapped both half shafts, as most of you guys know. Didn't get one run at all.

 

I didn't know. That sucks. But that's motorsport isn't it.

One hard launch was it ?

 

My first attempt today actually, snapped them both like twigs. I'll get the video up soon. Will be throwing my TT subframe in now.

 

That's unreal. Hopefully the r230 rear end can take the punishment tyres obviously hooked

 

lol slicks strike again

 

What size wheels / tyres are you running? Are they 15"?
Sucks about the breakages, the 5 bolt shafts are a known weakness but I don't think I've heard of anyone breaking both in one go though. Good effort

 

Tyres are mickey thompson ET street 255/60/15

 

I may have missed it, but have you got a power figure yet on E85 with the mostly factory setup (factory manual turbos, dumps, intake,etc)?

This is extremely relevant to my interests

 

No dyno results as its not something i really care about

 

Guys will the factory 2+0 TT tailshaft work with the NA gearbox? Or will it need to be a modified at the gearbox end.
