Topgunz - air to air upgrade

Senna-F1 · 12-19-2017, 12:50 PM

Hey Topz, I bought the GT-R plugs as well as part of my pre-build buy list Google Sheet. I too though will still need injectors and adapters.

So maybe it wasn't a Tbatt brace, seems JTran did this one, but maybe it's overkill for anyone running even your smallest pulley? Can you talk about pulley options yet?

So just ordered my Stillen SC

TopgunZ · 12-19-2017, 12:58 PM

That brace was used when guys were trying to run COG setups. Any bit of flex would throw the cog belt off enough to chew it up since the COGS do not have sidewalls like a ribbed pulley. I also went through 3 belts trying that. The brace you see (which ended up on my car) is not needed.

Is something needed if running the 9 psi pulley and maxing out the supercharger? Yes, a little more tension on the belt and pulley. This is accomplished by the above picture. Only my kit will be running a 3.12 serp side, 2.95 SC and 3.33 Jachshaft so there should be even less slip or zero.

I go MIA for 4 months and Topgun basically has his own kit ready to go congrats !

Kits running great with e85 and a couple extra goodies i had installed with CJM mostly a weekend car but living in Chicago its been put away for the winter/salt. Planning on taking the blower out to get the SI trim / impeller. is this the best route we are taking still for maximum gains? lol and where is everyone getting the 9 lbs pulley still?

TopgunZ · 12-19-2017, 03:49 PM

Yes, the Si trim is the way to go.

To spin the charger faster you can either source the 9psi pulley, which is around $200 now from places like ConceptZ, and add a pulley or tensioner to prevent slip. Or, swap the supercharger and jackshaft pulley which are $100 each. But you have to have the right combination to avoid running out of tensioner or you will need to buy a larger tensioner idler pulley.

Hey could be worse, back in the day we were machining longer stroke tensioner brackets..lol.. Live and learn.

This is why I am making a kit that just has it all done for you guys. Si trim and all.

Just to confirm for us California folks.... since this looks like the stillen kit (majority), it's still CARB legal?

brucelidat · 12-19-2017, 05:39 PM

I am sure the answer is no. Even the Stillen kit doesn't get the CARB sticker if you buy the tuner one, only if you get the full kit with their canned tune. CARB is very specific.

Unfortunately it will not be CARB. brucelidat is correct, the only way to have stillen carb is the 8psi kit and their canned tune.

Which means you will have a CARB legal car that runs like crap.......

True, but once you have the carb sticker you can re-tune and when it's time for smog inspection as long as you have the sticker and don't throw any codes then you're good to go.

But, it wouldn't be worth the time (bureaucratic bullcrap) and money for topgunz to pursue the carb certification as he's going to sell a ton of these without it, even to California people.

True. I still feel sorry for you guys that have to put up with the CARB stuff. Seems a bit unfair in that the rest of the country can boost away while you have to live with 91 octane gas and emission restrictions that the rest of don't have to do. You guys should revolt and join the rest of us. It's not too late.....

You cant feel that bad for them, it just forces them into having to beg the wife a little harder to let them buy a car like a GTR, Vette or Viper.

considering the cost of living out there (and in many cases, the subsequent salary bumps) - those cars aren't nearly as expensive....relatively speaking ofcourse.
