Finally getting stuff done on our cars

[carltalon]

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/Wastegate-Actuator-Dual-Port-T3-T4-Hybrid-Turbo_W0QQcmdZViewItemQQcategoryZ33742QQihZ009QQit emZ190016964269QQrdZ1QQsspagenameZWDVW

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.

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.

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.

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.

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.

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.
