EFI and Boost

How many guys out there run EFI and of those who do, how many of you run more than 1.2 or 18 psi boost? Like to see some of the heavy hitters rides.

I plan on 2.0 bar once I get a MAP sensor that can take it (only on race gas and very limited use).

I have 1.4 bar springs and was running that with a Holset HX40, but now barely get over 1 bar with the new Borg Warner S366 due to the huge turbine.

Need to hook up the boost controller yet.

2 bar with a fresh clutch and fresh rear tires. If they are too hard they just spin. It depends on what I'm doing and if the conditions can handle it.

The directions seem harmless to solder in the MAPDaddy. Is it painful?

Cory. It will take more effort to pull the MS2 board from the case than it will to solder in the new MAP sensor. I am happy to help if you want. you just need to enlist a tech at work to use the soldering station.

Yep! The MS components are huge compared to the ones we use. Should be easy for them.

Nice!!!!! Thought their were many more cars out there by now, but maybe not. Have only seen a couple youtube video's of some high boost turbos. One was running 30 lbs. boost and put down 830 hp to rear wheels. Look like a lot of 996 and 997's out there but fewer classic turbos. Don't care for new turbos, power is still impressive but no style.

I'm almost 8.5, I was shooting for 9:1 But with the addition of the big valves, it took a little away. (next set of pistons ) Twin plug allows you 8-10 degrees less timing, But with a flat top piston, it doesn't shroud the plugs, so there is not really a need, it just adds a little insurance. Anytime you can make the same power with less timing it's a plus. High flowing turbo compressor/s, Large, high flowing, high efficient Intercoolers are a must, to keep the charge temps in check. Its the IAT's that you really need to concentrate on, to make sure the chamber temps will not suffer. As far as timing at 65-6800 @ 2 bar I'm at 18 BTDC and 16 BTDC by 7200. (But every motor is different so some may like more or less) My IAT's are about 10-12 hotter than ambient on full boost.
