Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

So what did you run today?

Re: Finally getting stuff done on our cars
 

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

Re: Finally getting stuff done on our cars
 

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. :D

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

Ahhhem, I am guessing things didnt go as expected?

Re: Finally getting stuff done on our cars
 

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

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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.

Re: Finally getting stuff done on our cars
 

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

Re: Finally getting stuff done on our cars
 

Re: Finally getting stuff done on our cars
 

That's it? ;)

Re: Finally getting stuff done on our cars
 

Not bad for 202 dyno runs.;)

Re: Finally getting stuff done on our cars
 

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?

Re: Finally getting stuff done on our cars
 

Best timeslip coppied.

.463 r/t(doesn't matter).
1.874 60'
5.140 330'
7.653 1/8 mile
97.66 1/8 mph
9.768 1000' mark
11.450 1/4 mile e/t
135.76 1/4 mph

That pass was the best of the day, also the first pass out. After a few more launches I figured out how to hook and cut my 1.737, 1.738, 1.757 60's. Then I had trouble getting 2nd gear after this pass. This pass I grabbed 2nd SLOW, and wasn't using the spray it was just a "non heatsoaked" c-16 pass.
I average +35-36mph on c-16 on a somewhat from the 1/8 to the 1/4, nitrous is 41mph when the car his hot, so I know its adding power :).
I just need to get the first 330' down and I'll be good to go.

Re: Finally getting stuff done on our cars
 

Heatsoak should be less of an issue if at all when on the bottle. Did you log AITs on and off the bottle? I guess it would depend on the setup but the drop in temperature should be significant. Either way you can tell the power is there, just need to put a run together. Like I said before, its all how you look at it. I think you are saving your cars ass since its spinning like fuck out of the hole. Without that your drivetrain might be in serious jeopordy at that power level. And since you drive your car on the street its not a bad thing.

But it would be awesome to see that thing get into the mids 10s a few times.

Re: Finally getting stuff done on our cars
 

Dude, why not gun for an air-to-liquid intercooler setup? They'd fit right where your SMIC's are now, and you could probably get a pretty decent sized heat exchanger to fit elsewhere. Just an idea.

Re: Finally getting stuff done on our cars
 

Yeah, they stay between 130-140 on the spray and get near/over 200 on just the intercoolers.

Re: Finally getting stuff done on our cars
 

Damn.

Re: Finally getting stuff done on our cars
 

Yeah, that is getting seriously toasty! Thought of spraying the intercoolers too, since you have nitrous in the car anyway? That car definately has a lot more in it, I think the turbo's would be good for another 100 whp too. I think you could hit 800whp w/o the nitrous with better IC's and external gates/better springs.

I started popping the WG open on my internal gated SCM61 around 32psi also. I have an idea to get you some extra boost if you are interested.

Re: Finally getting stuff done on our cars
 

I am always down for ideas. NO matter what we do, we can't get more boost out of them, and i have the HD wastegates.
I need a fmic as well. I am purging onto the intercoolers already ;).

Re: Finally getting stuff done on our cars
 

Suprising your aren't knocking with those AITs, that is some hot ass air. Even with more boost those turbos could be out of their efficiency range anyway, the air might just get hotter. A FMIC would help obviously, but with your goals Swanny bigger turbos are in your near future. If you went up a few sizes you could run the same 32 psi and have a better air charge and make 800whp on boost alone.

Either way that is some serious power. I will have to swing by some day and see if you can scare me.

Re: Finally getting stuff done on our cars
 

Car is stone quiet, but I am still somewhat convervative on the timing.
Pretty much the turbo's are tapped out, the intercoolers are tapped out, the charge pipe size is tapped out, and the downpipes are tapped out.
I could add more spray and I will change out the jet size if I don't go fmic and a big single.

Re: Finally getting stuff done on our cars
 

Take the actuator arm off, slide another spring (preferably longer with small coils) over the arm. Then weld a washer on the arm, far enough up to give some more pressure. Using a small coil will still allow it to close, it will just take more pressure.

Re: Finally getting stuff done on our cars
 

Have you thought about using an actuator like this and useing the top port to hold the gate closed Ive been thinking about trying one but Im too poor. http://cgi.ebay.com/ebaymotors/Waste...spagenameZWDVW

Re: Finally getting stuff done on our cars
 

That second gear problem is really hurting you. I was running 96-97 mph 1/8 miles speeds at a measly 121 mph trap. Your overall trap is amazing considering how low it is at the 1/8th.

Re: Finally getting stuff done on our cars
 

I think some of you are getting things mixed up, I talked to Swanny and he agreed the turboes are pretty much maxed. I am sure he could get a few more pounds of boost out of them with some modifications but I don't think it would yield any gains since the 50s are just going to push more hot air. Swanny would have to state where the turboes are most efficient, I think he said it was around 27psi which sounds about right.

I think he is on the right track with the idea of running a bigger shot of nitrous at the track to bring his AITs down more and turning the boost down a bit for street use unless he is on the sauce.

And I concur with Steve, that fucking thing is hauling some major ass after the 1/8. Imagine if you could actually speed shift the first few gears.

Re: Finally getting stuff done on our cars
 

The 50's "only" made 352 whp each on boost. Toss in the correction factor and you are around 430 fwhp on a dynojet. The 50 trim should be 74% efficient up to 35 psi. 50 trims love boost. I think he is just blowing the wastegates open. I just want to see what the 50 trims would end up doing.

Re: Finally getting stuff done on our cars
 

I think I am popping the wastegates open at 32psi, and I am going to try to remedy it. But the turbos are nearly tapped out as well.
I also need to get that 1-2 shift down so i can really bang some 1/8mph out of it. Most 3s's with my power are EASILY hitting 105-110mph in the 1/8.....the fastest being dr's 115mph 1/8 but that car is 800lbs lighter.
It will come with time, I just need to figure out the short track.

Re: Finally getting stuff done on our cars
 

Tack weld the wastegate flappers shut.

Are you AITs before or after the nitrous? The nitrous should help cool it down a bit. Bigger turbos are only going to make the intercooler heatsoak worse.

Re: Finally getting stuff done on our cars
 

AIT post nitrous.
AIT's are around 130-140 with the spray during the run (creep from 130ish at the end of first to like 139 at the end of the 1/4"
Without the spray? 130-205.
She gets toasty.
I really don't think there is much compressor map left at these boost levels. I have my intercoolers listed on 3si, hopefully they sell when I am gone, then I can afford to swap out them for a fmic.

Re: Finally getting stuff done on our cars
 

So why not save all this for winter time, so you can atleast enjoy the car some-what with what time we have left?

Re: Finally getting stuff done on our cars
 

Tossing on a FMIC on my car would take a weekend at most. The turbos are staying until winter. It takes me 5 minutes to up the jet size and 4 or 5 pulls on the dyno to tune for it.

Re: Finally getting stuff done on our cars
 

Thats why I have been wondering why people are telling you ways to get more boost out of it.
