I can't get any more boost out of them period. I'd like to see a 1.5L dsm make 392awhp on a 50 trim. The intercoolers don't help the cause, but I really don't feel like fucking with a fmic on this setup as the turbos will not produce the power levels I want.

So what did you run today?

FattyBoomBatty · 08-05-2006

Bigger, shorter pipes, smoother transitions, a 110mm TB and 3" downpipes = 50 more hp.

**Goat Blower** · 08-05-2006

Damn, that's some serious powah, especially considering the reading is much lower than the dynojet numbers I'm used to. If you can get that thing to hook and shift, it should be an animal, even at 4800 lbs.

That doesn't make any sense at all. Air + fuel = power. The size of the engine will determine where the power band is at, but not how much power the turbo is limiting you to (although the engine may limit you). This is simplified, but that is what the equations boil down to.

There is obviously a bottleneck in your system, but the turbo's aren't it. Either that or the VE of your engine sucks, which I doubt. The HP could end up being limited if the engine was too large for the turbo, but not if it is too small like you are saying.

You have to remember that would be like 460+ per turbo on an AWD or FWD Dynojet and Josh is running internally gated Mitsu versions, which aren't going to perform as well as a normal T3/T4 50-trim turbo.

Josh, does the 6-speed tranny have shorter gears? You have the 5-speed right? The extra long gears would hurt spoolup and make it much harder to stay in boost between shifts.

Shotgun! · 08-06-2006

There are a lot of shortcomings in the setup. I think he has done pretty well for what's gone in and how fast it came together. A 6 speed would help things and so would real intercoolers. But given it's been pushed more than driven, lets drive it and have fun for a bit. Summer is almost over anyway.

A//// Guy · 08-06-2006

The real question is what did he end up running at rock falls on Saturday!

Ahhh, sorry. I didn't remember them being internally gated. That will hurt the performance a fair amount. I just didn't get his reasoning behind why the turbo's were maxed out.

tim · 08-06-2006

Ahhhem, I am guessing things didnt go as expected?

**JET** · 08-07-2006

Hopefully nothing bad happened. It really sucks to put all that time and effort into it and have something happen.

**Goat Blower** · 08-07-2006

The six-speed trannies also come with the mucho expensive xfer case, the 5-speed setup is much cheaper to fix and apparently is more robust. Just ask Matt Jannusch.

niterydr · 08-07-2006

Yeah the internal gates are really killing it. I might try to unplug the wastegates to try more boost as I think they are getting popped open.
The sidemount intercoolers are heatsoaking at these higher boost levels, they work great for pump gas, probably up to about 550awhp I'd imagine.
Car runs great, just I have a bad 2nd gear syncro. Best pass was a 11.45@135.xxmph off the trailer, no nitrous. I babied the 1-2 and spun a 1.87 60' on that one. I turned on the nitrous the next pass and all it did was make me consistant. The car was down on power the rest of the day (I couldn't get the heat out of the huge cores, once it heatsoaks its over). Off the bottle it gained around 35mph from the 1/8 to 1/4, on the bottle 41mph, consistantly. So I know its gaining power, I just need it to hook up at the line and get the 1-2 shift clean (new syncro). I didn't get a clean shift the rest of the day, ran a bunch of 12.0-12.2 at 125-131mph. However it was a good day because I learned how to get consistant 1.73-1.78 60's and keep it straight in 1st gear, I'll get some tires on there and a new syncro and be golden!

Its all working out bugs, and thats what I do. I just hate making baby steps with parts that I know are holding me back. I am going to give it one more trip to the track on the current setup (hopefully with a t-case housing and sticky tires, and a syncro) before I start to sell/switch out components.

A//// Guy · 08-07-2006

Nice runs!! Its great that its running well and putting down consistant times! Just wait till the air temps are in the 50-60 degree range, that should help.

turbotalon1g · 08-07-2006

LMAO, i smell new setup!! Peter hit it on the head, wait till sept. when the temps are much lower. Just to think at night on the street the ambient temps in sept. will be 40-50F

AJ · 08-07-2006

That's it?

**Goat Blower** · 08-07-2006

Not bad for 202 dyno runs.

EvilEvo · 08-07-2006

Sorry to hear the car still doesnt run right. It really sucks when you spend all that time and money on a car and it still cant even make any decent passes

Could you scan in one of the whole timeslips so I can compare some of mine to it and see where your car is hurting?
