Btw, what wires do you use for sensors so you won't get an interference?

I was having serious rpm drops (to zero).

What filter are those mentioned here?

That's fine, you shouldn't be worried much, it's because of high sampling rate and resolution of the stand alone unit you're having :lol:.

In 4th gear that's pretty impressive.

No 3rd-4th gear 100-200 video? :)

Yes later. :) Now its too cold roads to get any grip on 3.gear and also worn tyres...

btw, are you using T4's original clutch throw-out bearing?

I just got my clutch back from the balancing. Had it balanced just in case. Starting installing it at the weekend.

You really need some kind of traction control. I'm doing 60 feet 2.01 sec riding some old and poor 195/50/R15 Toyo R888 tires.

You are correct. I could use electric boost controller to get base boost on 1. and 2.gear and full boost 3.4.5. gear. Also my tyres work better when hot like +20'C, now it was +10'C and track was very dirty after winter.

Low 12s should possible. What was your best 402m time and trap speed?

Last year I made 12,26 sec, trap speed unkonown. This year 12,46 with 199 km/h trap speed and 2.01s 60feet. That was on "low boost", 2.2 bar only.

Some action/testing of the high boost today

Holy crap it runs nicely on those videos. :) On those videos did you use those R888 tyres to get grip? Do you still have stock intake manifold?

Very very nice. :) Im interested to know how your car makes more power when raising boost and mine does not. We tested on dyno to raise boost from 2.0bar but it did not make any more power and ignition timing did not have eather help.

Your car seems to have same power as mine on 2.2bar boost as mine on 2.0bar. 2.8bar your car seems to have about 600hp on engine.

Do you still have N/A cams and what timing settings on those cams? Whats your injector size and duty cycle on 2.8bar E85? Thanks for answering. :)

We did not test on dyno to adjust exhaust cam to have more overlap, it could be help in my engine because manifold pressure is much lower than intake pressure.

Mine has same behavior on dyno, raising boost and adding ignition wasn't showing expected power rise. But, as you can clearly see, there are some extra ponies under the hood on the road on high boost :). Injectors are 1600 cc/min @3 bar and they are opened almost at 100% DC. I'm using mixture of 80% of the ethanol and 20% of the gasoline. Intake cam is few degrees retarded, exhaust is at 0 position. N/A cams.
