Topgunz - air to air upgrade

G3RSTY7

Where is best place to put wideband? Where Y pipe joins I suppose after cats/TP’s? And for flex fuel tuning is it best to start off full e85? Car show this weekend hope install is done and waiting on base map from Seb tryin to not bother him too much just hoping car is good enough to drive to mountains

I just had Specialty Z install my 2.85" supercharger pulley. My old numbers with the 9lb pulley were 541whp 440 torque @ 10 psi. My new numbers with the 2.85 pulley addition are 586whp 486 torque @ 12.86 psi.

Wow is that just with Si impeller or did you change the jackshaft as well?

Jackshaft is stock. If I was strictly running e85 I would have had the 3.47 jackshaft installed but I'm on flex fuel (91 octane). Seb had to dial back the timing on 91 as it is on 12.86 boost.

This is awesome. Nearing 600whp and 500wtq on the upgraded kit!!

2 years ago if someone told you they made that power out of a centri blower on the 370z you would have been laughed at and ridiculed as being a liar.

Winning!

That car must be an animal

I love the way it makes power. The extra 45ft.lbs. made the difference.
If you look at the dyno sheet, the power drops completely off at about 6900rpm. I asked Seb about that and he said the throttle is staying open to redline but boost is dropping off. He thinks the air filter is restricting the air flow to the sc. Beyond installing the turbo guard screen is there anything that can be done to get more air flow? I'm assuming the stock stillen boot and filter more restrictive than the filter that's on it?

Isn’t the 2.85” the 9lb pulley? Wasn’t your old pulley the 8lb? Crazy numbers you’re making me want to say hold the phone and throw on the 2.85” but wanna make sure everything is kosher first. Tuning for flex but I plan to run e85 90% of the time but i guess it’s that other 10% things get dangerous

The 9lb pulley goes on the jackshft on the serpentine side. The stock serpentine jackshaft pulley is 8lb. The 2.85 is installed on the supercharger.

I'm running flex. Same thing, e85 90% of the time. The only time I'll be on 91 octane is if I take a trip and e85 isn't available. Seb pulled a bunch of timing on my 91 tune (for safety) and and primarily set me up to make all my power on e85.
