So I started my turbo build. Using and SPA manifold, t3t04e turbo. Tial wastgate and BOV. 60 lb injectors, 2.5 inch intercooler piping. 3 inch blow through MAF tube. 3 inch exhasut all the way back. Just had a question about the J&S everyone talks about. does everyone with a turbo run this safegaurd? The car is not going to run any longer than to make sure nothing leaks and drive on the trailer to go to the dyno to get tuned. Ill post pics later of the progress.
Just an FYI... It seems that everyone (including myself) who has run a 3" Blow-Thru MAF housing has been through hell trying to tune it correctly. There has been a couple of DIY'ers that have run the OEM MAF meter with a 2.5" Blow-Thru housing & the Diablosport MAFia. I plan on coverting to this setup when I return from deployment. My idle has gone to crap between the 3" MAF Housing and the Mustang MAF Meter being used.
Your issue isnt with the 3 inch MAF tube but with the tuner LOL, The 3 inch and the 2.5 are the same to tune its just knowing how to do it , yes blowthrough it a little trickier to do mainly because people make it harder then it has to be in the tuning part
Even with the 3 inch MAF you will need the diablo MAFia , loose the not needed Mustang MAF and use the Focus MAF , Never understood using the Mustang MAF
Put it this way had I bought a J&S when I installed my turbo I'd probably still be on my stock motor....two sides to that, I'd still be on a stock motor and would have a little fatter wallet and I would still be on my stock motor and probably would feel as safe running 20pounds of boost....I say get one its money well spent.
Not that I have a bunch of experience with tuning, but I have to agree with Tom. A lot of shops don't understand that the SVT is a lot different than a typical Honda or even a Mustang. Even if they're good at tuning Mustangs, it won't mean they're good at tuning SVTs.
Im getting the turbo mounted this weekend, and the custom down pipe. Just wandering what type of gasket do you guys use with the SPA manifold to the waste gate flange? more pics this weekend.
I think they're like the turbonectics wastegates where they say a gasket isn't neccisary but don't know for sure with the SPA, you could use some of the 2000 degree sealer that I've seen if you can find one
^^^ what he said. They say a gasket isnt "needed" but when i put my spa on im going to use some high temp sealant just in case the two surface aren't flush with eachother.
Ive talked to many ppl about it and i have only heard of that happening on one or two. And everyone else says that they have had no problems out of it. I hope i got a good one.
Yeah I will get the JS as soon as i can. I guess he isnt making them right now. Once it is tuned im am going to take it easy on it untill i get my js. It has a stock clutch in it as well, which probly wont last too long. the J&S saregaurd is a ignition control module that can modify the timing to prevent detination.
Once it is dyno tuned i want to take it to the Ford nationals at Carlisle. Keep the rpms low, not beat the car. Think it will make it a weekend like that? I cant seem to find the JS anywhere in stock.
Just to chime in, I also don't see where to find a J&S. I definitely need one as I'm shooting for over 300whp daily driven. I went to their main website and it looks like you can order over the phone...but they don't say if it's in stock or not. Doesn't look like CFM is giving an ETA on when they'll have it.
Personally I would NOT run the car without the J&S...
And NO I dont think the motor would last the weekend without it... you can NOT use the stock knock sensor (ECU wise) to control knock on the SVT with ANY type of Fored induction.
well that sucks, looks like no for nationals for the foci this year. Unless i can find a JS in a hurry.
