if your running the stock kit 8PSI, Trans cooler and oil coolers, Frozenboost heat exchanger are a must You'll also need to make sure your tuner ups the trans line pressure and turns the cooling fans on earlier . Mine started to really pull like everyone else's 3100 RPMs or so all the way till red line. I remember the first few times I made pulls, I hit the rev limiter hard LOL came super fast!

I don't think you need it, I've been waiting for it to give and had plans to do a Level 10 but it's shown no slipping at this point. You will see a lot of post that say you can't use gears 5-7 but I use 5th at WOT all the time at the track. My tuner did adjust the pressures to make it shift faster and it has a cooler but that is all we did.

Any of you guys with this kit regret not going turbo? If so, any reason other than the higher power levels?

I am also reading that centrifugal SCs have a sort of lag as well. Can anyone comment on this? I'm not really gunning too often. Most of my time is spent between 2.5k to 4.5k. I only get into the higher RPMs when driving come open canyons or passing at higher speeds. My concern is that I don't drive aggressively enough to really feel the gains since they come on gradually, whereas with tt, there's massive trq pretty early. On the flip side, tt costs a lot more and I am not sure how often I will actually get to utilize that massive power as well, though it's effects int he low end should be felt more.

I really don't have any regrets other than try to get to 500 WHP. At 420 ish WHP ( I was 412) I should have been happy LOL , and just maybe made it and AIR to AIR kit. I'm still tossing that Idea around if I can find just the SC and engine bracket( Used) I can make the rest :). But for what it was built for mid/low 400's its good. I had no lag issues either. IT woud just build power. You might be feeling heat soak.

you need a turbo kit bro.

If I did this whole build again, I would go turbo in a heart beat.

After driving a 370z with a BP kit, theres no comparison.

the sound, the feeling.. everything.

Agreed.

I have the BP kit and it's about the same cost as going with the Stillen kit. The upside is you don't hit a power wall around 400-420whp.

My boost threshold is around 2,500rpms and turbo lag is just a couple hundred rpms so there shouldn't be any worry that you'll never be in boost. In fact I think you would find it, if so inclined, hard to keep it out of boost under anything other than slight throttle.

There's nothing like the feel of a turbo car. Especially one on the VHR motor. This platform was built for boost. It should of come that way from Nissan.

I agree with guys above just for me having a X and auto my goals were different. Trust me tho this the trans and or TCASE wouldnt blow out of the car with a TT kit I would have went that route. I still wanna get the AAM kit but I know my trans wont last and to build it on top of the TT kit just to much $$ for me know( Looking for another house)

For me and my 7 Speed Auto = S/C. If I had Manual Trans would have = BP. All in all I smile every day driving her! :tiphat:

Oh he has a Auto trans, my bad.

Yah SC is probably the best bet for you.

Yeah. It's nice to not have power limitations due to tranny. Instant torque from a turbo isn't good on the AT

I would upgrade the transmission if I turboed. The question is is the extra power and low end grunt worth double the price of sc and lack of carb peace of mind.

No regrets for me and mine doesn't have lag. I like the lineal power delivery it gives on the track. Unless you drive the car like an 80 year old grandma there is no way your not going to feel the power. I was driving a friends supercharged C5 a couple weeks ago with my wife driving my car behind me, we took of from a stoplight and she went to pass me and hit the gas ( she drives a Veloster turbo so she didn't expect the car to jump) hard, she about crashed both cars when the SC came to life.

There's no lag with any kind of a supercharger. It's just that the centrifugal won't build full boost until the rpms are high.

:eek:
Well a big :tiphat: to you for being the ultimate test mule, and thanks for sharing it all with us. You have helped me decide on going with the Stillen s/c. I find it amusing that some folks bitch about 415WHP in a 3200lb car. :icon17:

I get wanting a monster street car but I always wonder how many people have driven a 400+WHP car, it's not the fastest but it's a ton of fun if you use it.
