Unless you have upgraded the oil-pump, don't exceed 7500rpm.

fair enough, have any idea what oil pump people are upgrading too?

Nismo oil pump @ US$1250

I ran had my limit at 7800 , but never hit it shifted at 7500 to so I think I may have bounced like 3 -4 times at the track tho, I shift manual ALL the time and took some getting used to how fast the RPMs ramped up

Hey Mikey !!!

Check your Dyno Graph ... and look for where the Torque Curve starts to dip ... That's your shift point.
You still may show HP increasing but you will be losing the rate of acceleration.

Do some testing, and you can fine tune the shift point to your liking as needed.

If you did the pull thru the gears you may notice a different shift point for different gears...good to know if you plan to race.

I ended up installing an Auto Meter Shift Light (guage style) using an 'A Pillar Guage Pod' crafted by 'Gale Force' - one of the members here.
This shift light allows you to program each shift, and being located in the guage pod, it is much easier to see than the OEM one ...

My dyno graph indicated to shift between 6900 and 7000 (with some other performance upgrades) and that worked for me.

Sweet, good to know about being able to program the shift light per shift. might look into one as well :D

still debating whether to go the e85 route.. waiting for some results from another member doing the same, as like everyone else we really don't know how much gain there will be as we can't just up the boost like a turbo setup, we could however increase timing/tune afr more aggressively.

Every Stillen supercharger that seem to have had trouble seem to be when people try to get more power out of it, be careful!

haha will do man!

won't be doing anything for a while, it's pretty good as it is already :)

I have seen some issues when people try to pass 450 whp. I've seen a few doing 430-445 whp without too much issue. Past that we are still testing right now. We are developing a high boost kit and are seeing what needs to change to make it safe and reliable power upgrade.

If you get that worked out call me for my credit card number!

Will do Jason :)

Me too :tup:

Me threes!

Not really anything with the kit "if" you only looking for 450WHP. I personally don't like the heat exchanger bolted to the radiator. You guys should really look at what I did and the hand full of guys here and followed me and used a front mount heat exchanger, there is plenty of room. The other issue is our MAF's( Voltage will max out) Myself and Cliff ran into this issue but again that's if your looking 470ish . I had your Impeller upgrade and UPREV MAF's an was pushing 457WHP and the kit held up fine!! How ever on the other side of that was the sh&t install I had of the fuel pump.

I also had injectors and DW300 pump. I had the pump only cause the dealer killed the wally, and injectors were just incase I reached 500WHP, Which you wont see unless you have a built block.. Boost will be to high to get there on the the stocker, My 457WHP was at 11-12 PSI. You need like 16 to get to 500WHP.

To make 450WHP on your kit you would probably need nothing other than the front mount heat exchanger. :) ..

yes please ;)
