Right on 4ring, the ignition system on the EVO is one of the worste parts of the car, actually the only really bad part on the car. Glad you found some smoothness and power in the DLI.

I agree and have been looking in to the DLI for a while. Do you know have them back in stock David? I know for a while they were on back order but that was a while back.

As of last week we had them back instock. We have also been shipping a steady supply of our COP's for the EVO which are about the same price. Right now we are waiting on some parts to finish them up again, should have them soon.

Low speed throttle response is much better now also. So far I would say anybody running more boost should look at beefing up the ignition system.

I run 28 pounds of boost and have no problem with the stock ignition. My car pulls very consistent at the track. Trap speed are always within 1 mph. I have stock plugs.

I'll try to answer. I have lived at 7000 feet before. Spool up is pretty similar for me no matter the elevation. I might spool slightly quicker at lower elevation. I would say the extra power you make with the 35r eclipses the little bit of extra lag you will see no matter the elevation. You have the realize the difference in lag between the turbos will remain pretty constant no matter the elevation. It might not be the answer you want to hear because it seems you have already purchased a 30r. Everybody that rides in my car says that the lag isn't as bad as they were expecting and I use an AVCR which doesn't spool as fast as the MBCers. I probably don't see full boost on high boost until 4600rpm in 4th gear and probably more like 5500-6000 in the lower gears.

Thx, I ran a 11.56 @ 123 with a 1.8 60' right after that one too. I cranked the boost to 28psi to get the extra power neccessary for my poor driving to go fast No cage for me though. Then I would have to run 30+psi just to keep up with the extra weight. I could easily rip off an 11.3 or 11.4 with the current power, but I doubt the track officials would care that much. Depends on the mood their in that day.

I don't think you will be able to get 500whp out of alcohol and 91 on any turbo, but the 35r would be your best chance. I just deal with the 'crappy' power on pump gas. The problem is that race fuel spoils you so 360 to 380 hp feels slow.

I am running the alky kit so it does put a little more stress on the ignition system. I tired a bunch of plugs and could make them work if I gapped them down to .023 but I really don't like doing that. With the DLI the car runs sooo much smoother, even off boost and at transition that it is well worth it. Nice times on the MAS

I did miss post number 10, sorry about that, not sure how I did.

The GT3076 spools a little bit quicker, but in the end I don't know if it is quick enough to justify the difference in power between that and the GT35r. The tune I did was on race gas, I don't know if something else was wrong with the car but I don't believe there was. I have seen a couple of Gt3076's now with dyno graphs and it seems as though they make around 450 AWD WHP. This is in the 278-28 psi range.

With 91 and alky, as you can see from what I wrote above, you won't make 500 whp. You will go over 400 and depending on everything else you have could actually get pretty close to 450 whp.

FRE,

I am impressed you have gotten by with the stock ignition. It is rare, good job with it though.

It is possible to make 500 whp on 93 octane and an alky kit. I saw Al do it but it is at high boost levels, around 30 psi. In my opinion that is too high for most guys to be running around with on a daily basis. It was accomplished though as I saw it with my own eyes.

91 oct and alky with the GT35r. I don't know, I hate guessing. I haven't dyno'd one like that, actually the dyno work here on the EVO's has been limited because of our old 2wd junk we had.

I will be able to get some great data very soon as the MD AWD dyno should be here any day now.

I'll give you an example of turbos, quick like

Good customer of our has a 2.0, mildly ported head and our GT35r kit on the car. With 94 octane and alky the car ran about 120 mph trap speeds. I tuned it, it was very very safe, knock control and all set up conservatively. This customer only wanted pump gas and alky. After driving the car for a few days while he was here he decided we should do a race gas tune for the car.

Guys, the difference in race gas and pump/alky is like night and day. This car at the same boost level was a beast on 118 octane. On 118 octane and 30 psi (instead of the 25 psi on pump/alky) it was down right scarey. The timing you can run with race gas is just in an entirely other league compared to what you can run with alky/pump. Timing is power.
