Highest HP out of a supercharger set-up

EP370z

What's the highest out put out of a supercharge set-up that people have done?
Looking to possibly do the stillen kit. Plan is to change from water to air intercooler to air to air intercooler. E85 conversion for starters.

2nd question does the supercharger have a bov if so where is it located?

Mine will be the record (**edit**) (IF AND)when its completed next month via the 2.9 liter whipple supercharger kit which will be the stage 2 kit from RJ manufacturing. If I were you id wait to see the results from my kit and their shop car which will be getting the stage one kit on a stock motor. My kit will be on a fully built motor with a bryant racing stroker kit. Also a fully built transmission. With the right fuel set up we're expecting some very high numbers and should have some real world results very soon

If the stage 1 has the whipple whine then I'm game.

Also they are taking names for pre-order and i believe the first 10 people will be receiving a nice discount near a thousand dollars if im not mistaken. The stillen kit with a custom tune and all the supporting mods you can throw at it will net you just over 400whp depending on the dyno used and environmental conditions like temperature and humidity. There are some guys reaching around 500whp using a forum member's air to air conversion kit that modifies the stillen kit from the air to water system that's sold with it from stillen. Stillen's kit is around 6-7k and with supporting mods and custom tune can easily cost over 10k. While the stillen kit has been on the market and made to work like an oem system it's been known to cause problems as severe as a blown motor or trans. The new whipple kit is supposed to be in the sub 10k $ range and offer a diy installation and near 600whp power levels from the stage one kit. There will be 3 stages to the whipple kit which is 1...1.5...and stage 2. I believe the difference in the stages as far as the kit itself goes is mainly the size of the pulley used but obviously depending on your power goals you will need to upgrade your fuel system and possibly the internals of your bottom end. You should ask rj manufacturing about all the details as i am just a customer not an employee. My info may not be 100% accurate but i think im pretty close. Just trying to help a fellow forum member. I have nothing to lose or gain by you going either way after all i currently have the stillen kit because I prefer the power band of a supercharger to a turbo kit. Im going with the whipple kit now because i can finally reach the big power goals I have that i couldn't reach with the stillen kit

Gtm/gamma stage 2 kits are good for over 500+ hp with 93 octane with e85 you could be close to 600 whp my BOV is located passenger side intercooler pipe behind the bumper
I'm running 523 whp with just a pulley change and tune
There is a twin supercharger setup from gamma ...but very pricey ...all in all best increases for the money is a turbo setup ... just depends on what you like

But to answer your question, StillenZ84 made 560whp on the stillen A2A setup which i believe is the highest recorded SC on a 370Z. He is going for over 600 this summer. His videos are under Boosted Z all over Youtube. He leaves some serious competition in the rearview.

The whipple should be able to make power much easier though, if it comes to the market.

Any turbo setup will make all the power you need also.

There is also that Q60 that hit 561whp (11psi A to A) which I would say is a fair comparison being pretty much the same application.

Did he do this with a filter? I thought he made a pull without a filter for that.

Are these with e85 ...or 93 octane ?

phunk

who knows... probably wouldnt make a difference though unless the filter he runs is way undersized.

I think most of the people on here would like to see the RJ Manufacturing SC on a stock block. Most people are not going to go with a fully built stroker motor. I seems utterly pointless to post those numbers. Didn't Swiss370 get 560 with a Stillen/Stroker/Frozen Boost?

It is undersized. Thats the bottleneck of the whole system (well, air to air anyway) . The SC volute intake sits so damn close to the radiator there isnt enough room for it to breath properly with a filter or boot on it. When i took my filter off, I was on my way to over 600whp but belt slip kicked in at 6800 and it fell on its face twice. Wish i had that extra pulley on there at the time.

If we could set the sc back and have room for a nice big filter then the V3 would be making 600 all day on our "non stroked" VQ's.

id be curious to see the results of a before and after with the filter. the stillen filters look to be about the same surface area as the filters we have on Justins Z (ordered wrong ones) and it had no trouble making 701whp at relatively low boost.

Have you ever tried putting a vacuum gauge on there to see how bad it is?

I definitely understand your point but the the question asked by the op was inquiring about the record for SC'd 370z and my car should be done in the next month or so..we're getting really close. My transmission should be finished by fast intentions in the next couple weeks and Bell should be shipping the heat exchangers in about that same time frame. Im getting seriously excited. I can't wait to hear that whine!

B&W_Evader

Don't get me wrong, I can't wait to see some pics and vids of your setup. Is the top view going to look like the kit on a stock block or are there a bunch of other upgrades?
