UK R8 V10 + Heffner TT - Santa delivered early!!

[Nudenut]

Sorry guys, just been away and so busy over the last few weeks not had time to complete a proper write-up!

Install was perfect but had an unhappy high pressure fuel pump on one bank which slowed the tuning process, replaced it and started over, all good.
Brought the car home weekend before last but we are still finalising the mapping (touch rich on cold start) so may take a couple more map tweaks before I get it on the dyno for some figures on UK fuel. All testing/logging has been on the road to date which I think is a good thing for sure.

Can tell you now the car drives beautifully, the torque is so low in the rev range its a joy and past 5k you need dry roads or the ESP struggles in 4th !!

Will look to get some pics/vid & Vbox data up over Christmas!

[Nudenut]

Crank sir! lol... bang on what Heffner promise at 6psi so happy with that, think it has a bit more tbh

[duhawks]

Ah I couldnt see the graph until now. Wow that is good!!! Bet that is a blast to drive!

[Nudenut]

I LOVE it !!

[duhawks]

Just got a chance to really look at the graph. That thing is nice! Very nice power curve!

Now get that vbox out!!!!

Had a map tweak on the dyno last week :-)

GT wheels installed with Toyo R888's now for the warmer months... nice to have some traction :-)

[motormadj]

Very nice indeed!

Would love to see some more videos of it.... what it sounds like idling, driving noise in car, noise out of car etc, that would be great!!
