I rode in the New and improved Altima Coupe CVT turbo..... noice!!!!

[rjdmmfl1]

EVen at 4 PSI, this thing is still pretty freakin quick..... still a G37 killer by far!!!!

[alt.coupe28]

details doc?! mmooore details!!! hahaa

[Infantry1327]

I didn't think Blake was going to re do his turbo. I hope he got the cooling under control and I can't wait for the meet.

[marcelo929]

Damn that was quick, I thought they would take longer to fix it. More detailllsss!!!!

[Mr. Music]

Good to hear that the car is up and running good again.

More detailllsss!!!!

[Infantry1327]

I just talked to blake. He just got back off the aircraft carrier yesterday and he picked up his car. They have done alot of coolent work to hopefully keep the transmission running cool. So far so good, but they still have a little more work to put in and test it a bit more before he can bring it home.

So be patient and Blake will post up all the details when he gets a chance.

[alt.coupe28]

thanks for the update infantry. so far so good for the first cvt turbo coupe!

[marlin29311]

Im interested to hear more!

4 lbs. is probably around a 30 to 40 whp gain max. It's not going to be a major difference and for the money spent could be beat with tune, headers, exhaust, intake, etc. Are they planning on running the boost up any? And, what was done to cool the cvt?

I understand where you're coming from.. but again, even at 4 PSI (which is really low) this thing is still really quick. I've driven G37's and I am 100000% positive this thing will smoke a stock G37...

I'm actually on the phone with Blake right now.. he could do a much better job of explaining things than I could... and I'm sure he will do so later tonight!

[Infantry1327]

I talked to blake a little while ago, and things are running great. He put a dragster transmission cooler on it and the operation temp has dropped from 220 to 140. Once it has been fully tested and is sure the cvt can take it, he will up the boost.

Hope this anwers some of your questions. I am sure Blake will come on when he can and post more details

[Hussain]

so is it 220 degrees on a STOCK CVT or was it at 220 with the last turbo set-up? did he manage to keep it cooler then stock with the turbo on

[adidas2go]

Ok guys, 4 hours of traffic and I made it back from San Diego to my home in Camarillo.

The turbo is installed exactly the same as it was last time, however, this time we installed a massive transmission cooler with sensor and gauge in the car, in the upper portion of the STILLEN fascia. This lowered the operating temperature of the transmission between 120 (going 70 mph) and 180 (idle in traffic). The previous N/A operating temps of the transmission were between 180 and 220. Past 240 (which would occur under heavy boost in high outside temps), the transmission fluid started to boil and this is what ultimately caused the pressure sensor failure, that killed the first transmission.

So that is the big thing, protecting the transmission. Now for the boost. We installed a 4 psi spring in the wastegate purely for testing. If the transmission shows no signs of malfunction within our testing period, we will install a larger spring, and turn up the boost.

Now, for what Warner said. A common rule of thumb is for every psi of boost, it adds 10 hp. However, for you Warner, to call me on rules of thumb, would mean I would call you on your bishez for only pushing 7 psi out of your turbo, and claiming 100 hp increase. So you obviously know, the tune has just as much effect on the output power as the boost pressure does. At the 6 psi we ran the first time, we ran the stock computer. It made all the corrections, and ran the motor incredibly rich. Not the best for power. So, now we lower the boost to 4, however, Split Second has stepped in, and created a brand new piggy back type to the altima coupes all digital sensors/computers. So, in turn, with this computer, and the map programmed within, constitutes an almost identical increase in hp. Of course, a larger amount of boost has more potential to be harnessed into hp, without the proper tune however, it wont produce.

At any rate, my car is running good and strong. I will continue to post updates in this thread. Nice to see you guys still have an interest in the CVT Turbo

[psi101101]

where did u buy the turbo kit from??

[adidas2go]

I didn't buy the kit from anywhere. Speed Force prototyped and built this kit from scratch.. Speed Force Racing is selling it here: http://www.speedforceracing.co...o.php

[Infantry1327]

Blake you know if your boys at speed force want to put this system on another cvt for more accurate tests. You know who to call. 2 is always better than one.

Double the pleasure, double the fun.

I am glad your car is up and running, and don't forget to hit me up tomarro so I can take it out for a spin.

[Hussain]

did you guys see what they did the the hybrid race car? the hybrids are CVT's so i guess it's a CVT with 400+ HP and they say they are going to race it so they must have got it to take some abuse without over heating or anything.... wouldn't hurt to try and see what they did to it

[uh-oh_8_coupe]

congrats dude, that's bad ***, i doubt theres a turbo or supercharger for the 2.5? i know the older alti's and se-r's had em, any chance for the 2.5ers?

[dangeris]

So it sounds like SFR is close to finalizing the turbo!

Blake, will this transmission cooler be part of the turbo package and will this increase the price? I'm sure it will since it is requiring new components

[adidas2go]

This will not increase the price of the kit

[psi101101]

congrats dude, that's bad ***, i doubt theres a turbo or supercharger for the 2.5? i know the older alti's and se-r's had em, any chance for the 2.5ers?

oh yeah, what about for the 2.5s?

[alt.coupe28]

nice!! glad to see your car is up and running again bro. i remember the first time we had a post of your cvt turbo. you were like the superhero of the a/cs! hahaa. but yeah keep us updated!

[adidas2go]

oh yeah, what about for the 2.5s?

I will get some information and get back to you guys. Seriously, if a 2.5 in the socal area wants to pony up the money and do a turbo for the 2.5 community, Speed Force Racing could do a turbo for you guys too

[mikegtr06]

how much money would said 2.5 have to fork up ?

[adidas2go]

I'm not sure, you would have to call Tim and ask. His number is on speed force racing's website

[JDRosenberg07]

+1 for the 2.5 turbo..

I know there are turbos out there that fit the QR25.. they just dont have a kit for our a/c..... yet

[ItsEcko06]

+2

me want but scared abt it breakin my car.... i love my a/c

[Infantry1327]

thats why blake is our test dummy. lol

[JDRosenberg07]

thats why blake is our test dummy. lol

Or why you get the 6MT instead of the CVT
