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?

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.

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.

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.

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

Damn.

**JET** · 08-07-2006

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.

niterydr · 08-07-2006

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

TheBlizzard · 08-07-2006

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.

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.

**JET** · 08-07-2006

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.

carltalon · 08-07-2006

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

**Goat Blower** · 08-07-2006

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.

TheBlizzard · 08-08-2006

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.

**JET** · 08-08-2006

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.

niterydr · 08-08-2006

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.

**Shane@DBPerformance** · 08-08-2006

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.

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.

**Halon** · 08-08-2006

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

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.

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