AllTrac.net Dyno Top Ten

[EricGT4]

Yeah it hits a little later than I would like it to. I feel like it kind of has the SRT4 syndrome. It doesnt really get spooled until 3500rpm. I am a little surprised that it came out that way but maybe thats just how the .50 roles or maybe my exhaust is not big enough. Its only a 2.5inch. I am going to get some bigger injectors in a few months and have it re-tuned at about 18psi and have the redline bumped up to 8 grand so we will see what I am pushing then.

Here is a link to my project thread that has the full build on it. Maybe that will explain some of the map questions.

It would be nice if on the first couple posts we had the dyno list link to the dyno sheets...!

will get dyno sheet later but...
after all the changes (ems, ignition, trans, diff)...
341whp. f'ing sweet. i could not get the dyno to read my torque, the ignition signal post ignitor is noisy or something? i need to make a loop cable pre ignitor.

@Mafix: i just saw that you also run a Haltech. I'm having problems with the ignition at over 1.1bar of boost. The home edge should be falling like the trigger edge but I can't get it to run like it should. Could you share your settings with me? Thanks!

[Mafix]

which series haltech? what are you using for a signal?

[abraxxa]

A Platinum 1000 with the stock sensors from the distributor.

[Mafix]

what plugs and what is firing them?

[abraxxa]

I had NGK heat grade 8 and switched to Denso IK22 this year. The rest of the ignition system is stock.

[Mafix]

you need bkr7's at a 20 thousandths gap

[abraxxa]

The IK22 are the same heat grade as NGK 7th.
The gap is 0.8mm like they come out of the box.

ik22's get eaten in these heads for some reason.

[abraxxa]

Most of the guys in the gtfour.ch forum have them for years without problems.
But I'll swap them for my old PKR8's and give it a try.

[MrDB]

det kills IK's v easily...

[sleeper]

I`v been running ik24`s for a few years now.. and they seem to work great..
