well yeah, 6500 is nothing crazy. No, the JT/YSI have about a 5,000 impellar speed difference. The YSI is in its own league. I did the same thing basically, first get the car on the dyno to see how high your taking it, then at that point you can figure out how much he is overspinning the S trim, what blower will be in its efficiency range, and what pulleys to go with. But if he is ever considering JT/YSI, a stock crank pulley wont cut it. Good luck with it all, should be a fun ride when its all set up

So how did this go? I have almost the exact same set up coming together...

MMR 1000
YSI
2.8 RR upper
10% OD IW dampner
Edelbrock / 6061
stage 3 cams
LTs

love to hear how yours turned out

Why not just go turbo at this stage in the game lol

it's not close to done yet. well, the car is, just no ysi yet. due to budget constraints he's keeping his v2 s-trim on for now, his tune date is set up for march 13. so it'll be a 4.75 with stage 3 mmr heads/cams eddy intake, gp 1000 fuel setup, 80lb injectors, full exhaust, 2.8 rr 8rib pulley with stock size crank pulley, intercooled, and instead of upping to the ysi he invested in some n20 so we're hoping for 500ish on boost and 650 on spray. only thing that's kind of limiting him is the headunit and pump gas.

because i'd be the one stuck with installing it and i do not feel like messing with headers or turbo installs, i'm sick of working on his car lol.

97stanger

its scary how close your buddy's build and mine is

ctgreddy

I know i've asked you this before, but which headunit are you running right now?

Mustang_NTriangle

650 rwhp at 6500 rpms 700 plus if higher redline. Sounds like a nioce build man.

currently an SI, but will be in the market for JT/YSI after all the shows/meets this year. I'm pushing 18psi out of my SI and on colder nights upwards of 20psi and its just WAY overspinning it at this point

lol

Yea, I hear ya man.

Ive my car breaks its gonna sit in the garage under a cover for a year before I try to fix it haha
