Thats a .91 ar compared to the .88 but yea thats pretty close to the same dang thing
What you guys think of PTE wastegates?

put a twin scroll with a spool up valve, on there. lol
Well the turbo should be here on friday or monday. Thankfully I can just go pick it up 1 mile down the road at the UPS store.
I got the needed flanges and all that stuff coming so hopefully it gets here on friday and I finally have a whole weekend off where I can work on the stuff.
Although im excited about this new turbo, i dont wana kill the engine or hurt it so low boost is a must off the rip with the new one.
Another thing is im at 80% DC on the injectors now so if it flows more ill have to keep the boost down but still efficient i hope. Damm car just takes all of my OT money!
Seems that the turbo i have coming(s366)is pretty popular on those rice grinders. Impressive numbers on alot of them though.
At last turbo pics. I think it will work well i just need the v band specifically for the borg warner. My dumb azz saw 4 inch v band on the turbo specs and welded out a 4 inch vband to a 3 inch reducer... well looks like ill be waiting on more parts.
Ill probly catch hell over the wastegate placement but it was needed on this set up. No other choice. I feel that with the angle it should be ok, but if not I will have to just cut in another gate on the pass header collector.
I added this puppy between the headers, which i should have done last year. The flex pipe.
My 42 lbs/hr injectors didn't work out as well as I would have liked so I had to go to my smaller (32 to 38 lbs/hr, depending on the source) and driveability was greatly improved...
Damn Six, you beat me to the punch. If he don't take em Mark, I want em. I'm only seeing 60% duty on my 36's at 8psi, But I see the turbo I'm looking at maxing them quick.
shame i have a new set of 65#'ers but they are peak and hold and dont think they will work with the 7730
I was using Low-Z injectors with my '7749, but I don't think I got the new sense resistor value correct, because it was never really smooth. I also didn't have the correct voltage compensation table for them which would only compound the issue, but I'm going to stick with High-Z, since they seem to work better at this point.

post up some data logs for me to look at , u can tweak timing and fueling below the low spool point to bring it in much faster.
will it spool against the converter with or without the 2 step?
The boost starts at arround 2800rpm makes command arround 4500 in 1st gear Then stays there the rest of the way. I'll take it for a ride at one point today and get a good data log. May try to up the boost a little.
I haven't tried the 2 step yet. i will though soon.

i know u have a new wastegate if u have a presure regulator for a compressor , hook it upto the bottom port on the wastegate and slowly increase presure 1 psi at a time and take note were the wastegate valve starts to open, iirc correctly u put a light spring in it , so im willing to bet the gate is starting to crack at around 5 psi
2,800rpm is pretty good , specially considering u have a good converter in the car now , u should have no issues spooling it at the track.
with some fueling and timing adjustments im willing to bet u can start seeing boost around 2,400-2,500 rpm
whats commanded timing look like from 2,300-2800 rpms
I drove it again and data logged it. Its just a sloppy tune overall. Way to rich but I went back to my last tune of last year that got me 11s. I have the exhaust capped off right now and i know that is messing with the afrs a bit.
Turned up the command boost to 14.5 psi. It gets it. Else then its rich... way rich 11.0 afr give or take, which is not good. It pulls ok. And the intake temps are ok, considering its 80*s out today.
I missed the MPH on the log..opps. The pulls on there are 2nd and 3rd gear. The last one on the sheet is 3rd gear only.
Any help on the timing and spool up is appreciated. I love the turbo, but im use to the tiny one that spooled fast.. Im sure Ill have to pull out the 2 step program for the car soon.
Also dave, Ill test the waste gate tomorrow after work. It supposedly is a 10lbs spring in there, I ran it yesterday on spring only and it was definitely solid holding 10-11psi at the max. I have the waste gate controller holding the duty cycle of the solenoid back at 100% until it sees 10psi of boost. This is suppose to help spool up by cutting off the reference air to the waste gate.
Now that I really look at my timing table and afrs on the way up to command boost....it seems weak and definitly could be slowing down my spool up.
Current timing table shown below. thoughts concerns?
I know the tune is crap and the afrs are all over. But also keep in mind i get a glitch every so often. So if you see a 17.0 or a 10.8 in a area that looks weird, its because of the glitch. I need to really work on this tune. A;though up top its rich i know that.
Finally here is a history monitor. The Blue is boost Green is Rpm and yellow is TPS. That the last pull i made on a 15 minuet drive yesterday and correlates with the table above and datalog also.
Here is the old GT3582 on the street to show the spool up top of 1st gear into 2nd. Good tune here.
Here is the S366 with the sloppy tune. 3rd pull spool up.
I know ive added alot of pics. But im happier now. Uncorked the exhaust with the cut out and a big difference. Now im over boosting like crazy.... and it spools alot faster. Still a little rich but Ill dial it in. Dam short shifted like crazy here too. 2nd and 3 gear yank with cell 38 being the shift
Update well i took the car for a quick spin before it stormed out. It was 85 degrees 60% humidity so it was a tad thick out there but I got a good log.
And a few flashes later, I feel pretty confident with the tune. Much more steady and not sloppy by any means. Only think i dont like is that my wastegate duty cycle is way way down there on my command boost but its nothing that will hurt me.
Quick story. The other day I turned up my timing on less then 5 psi and 90-100kpa areas. .5-1.5 degrees total in those areas. I also took my BOV apart and noticed it was gunked up and wasent moving too well, let alone the damm head was just a tad loose. So i cleaned it up. Tossed some SS teflon tape on the threads for the head and put it back together. All of the sudden it spools faster and also the boost is higher. I believe I had a good boost leak on that BOV but its fixed now.
I have a 10psi spring in the WG and now it only maintains 14psi. No big deal as is smooth and doesnt overshoot. I still am using the silenoid to hold back the reference to that gate untill 11psi which helps spool up a bit. The wastegate DC at 15psi is a mear 10%. I know with a larger turbo at lower boost levels you need a larger gate. Mabey a twin gate will be needed one day but right now it maintains and i knew id be running arround 14-16psi anyways.
So on sunday its my first real points race. Ill be sure to update on times. Truthfully without being able to use the 2 step in SPT class i doubt ill be faster then last year but i bet my MPH trap speed will be very fast for what ever ET i run.
And of course videos will follow no matter if its a monster at the track or otherwise.

Not yet dave. I gotta get my old lady to help me with that. Hard to video tape and shift at the same time. Ill get some vids at the track on sunday i hope. Ill get some dont worrie man.
This the log i just took. The wastegate DC gets outta wack at high rpms... 6k plus, the command is 15.75psi. And its still freaking hot and humid out that doesnt help my temps!
But this was 3rd gear..... winding it out. Yea i think i just pooped myself. I didnt think i would get up that fast so...well fast. Not doing that again unless its at the track. Dont ask me the MPH.....
Dave I uploaded the pic to Facebook so I could easily copy and paste it. I use that alot but didn't want to show off the mph. 123mph was the speed at the end. That's too fast For me on the streets. I'd be guessing that about 125 or 130 is the upper limit of the drive train set up. That would probly be 6500 rpms.

LOL. I took 84LSX and RubberDucky for a ride in mine at 8psi and brought it to 115, just kept pulling and pulling. Also gave it 8psi in 4th and 3/4 throttle, man will it pull for passing in 4th.

Ha....do i get a head start. Bracket racing right? You got that turbo set up rocking on your car?
I'm serious Mark, would like to meet up with you anyway one day, even just to say what's up. Ohio isn't too far from New Jersey, would be nice to meet up with some fellow thirdgen.org members. I've met three other members this year so far at a car show in South Jersey, still waiting to meet up with RBob he's supposed to come up soon, it was pretty cool. Yeah I threw in a T88, the T72 shredded the flywheel and in went an SFI plate. Then there was a VATS issue, had to swap modules due to changing steering columns, fun stuff lol.

I would definitly like to met up sometime. Between you, dave, and six shooter, sarr, and rbob...... you all are the reason my car is as successful as it is today. I was completly green and new to all of this 4 years back. You guys helped me out more then you know to help me get the car where it is today.

Haha, I remember when you first started, I kept saying your good for eleven seconds just the way you were, and nobody believed me lol. Now your knocking on the ten second door, that is just excellent, very proud of you. As for Dave, well, he's got the potential to be the fastest turbo V8 on the board if he would just focus himself for once instead of cutting his freaking car to pieces. He gets too carried away. Six, Saar and Rbob, all excellent tech guys, the board is lucky to have them. Let me know if anyone wants a T72, it needs a new 360 degree thrust bearing and that's because the clearances were too tight from the manufacturer, but other than that it's like new, and thrust bearings are only like fifty dollars. After getting pulled by the T88, I will never go back to anything smaller...

That and he needs to lay off the bikes or he will never finish it, LOL.

T72 too big for the 2.8? Muhahahahah
lol i dont know about that , i think orrz has me beat pretty good , though my whole combination should run into the 8's
as far as the bike i had an accident with it again yesterday clibing up a damn near vertical hill . wasnt bad at all and it was more funny then anything.
i was about 3/4 of the way up the hill and i started to loose traction once i got into the loose stuff so i tried to go sideways on the hill so i could stop and turn around , i didnt quite make it before i lost all foward momentum. i grabbed the front brake as i started to slide down the hill but it just locke dup the tire and me and the bike went sliding all the way to the bottom of the hill.
i have a gopro mount on my helmet and one on the bike , one of these days ill actually take the gopro or 2 with me
Let's talk a small shot of N20 to spool up a big turbo. Begin!!
Having seeing 2.2 and 2.3 60 foots yeasterday, and trapping 113 114 mph running a 12.9 13.0... we need to do something After I shelled out the big bucks for that big turbo.
Also it was mod boost. 13psi.
From that 3500 or so flash rpm to 5100 to command boost it takes forever! Literly.
on one race I got spotted well over 1 second and he caught me at the 330 foot then I pulled away. he dialed a 11.89 and I trapped faster by far. He was 109 mph I was 114 mph and I ran a 13.15...lmao
A taller gear should help with spool by putting more load on it. A lot of guys on the turbo forums are running tall gears and running good times.
i run 4:10's in mine spoolup was not an issue though, fast try putting the 3:42' or 3:23's back in it if u still have them i dont rember what u started with
also launch control , launch control, launch control

back in the day Holley sold a 75 dry shot system for the V6 3rd gen.
It used a return line restriction to boost fuel.
with all your computer sensors n tuning, I have not a clue. But sounds like either a cheap $300 [ wet or dry?] kit with a simple push button to activate as you see fit. Or a $5-700 kit to have it all contorled by the computer at once?
[ FYI ill be joining you soon enough, got hired into that new Home Depot warehouse they built down near where 280 deads ends. $200 ebay turbo here I come ]
