Boosting a 2.5

[Unfkwthabl]

Does anyone know how braille battery supercharged their 2.5 hybrid cvt without any cvt problems? I'm not to educated when it comes to boost but if they can do this to a hybrid couldn't it be possible to boost the 2.5 without any cvt issues? Can someone explain how braille battery acheived this? If someone could shed some light on this for me it would be greatly appreciated.

Heres a link explaining what was done to the car:http://www.autoblog.com/2008/1...ot-ro/

Does anyone know how braille battery supercharged their 2.4 hybrid cvt without any cvt problems? I'm not to educated when it comes to boost but if they can do this to a hybrid couldn't it be possible to boost the 2.5 without any cvt issues? Can someone explain how braille battery acheived this? If someone could shed some light on this for me it would be greatly appreciated.

1. Link?2. It's hit and miss with the CVT, they blow up even non-boosted, so take your chances.

CVT + Boost + 2.5L = Fail most of the time. lol.

A lot of ppl say its hit or miss. IMO braillle battery wouldn't sponser an altima pushing 440hp on a hope that the cvt wouldn't blow. Then again I may be wrong cause I don't know much about the car. I'm just trying to find out as much as I can about this car and seeing if they found a solution for CVT's under boost.

this car is AWESOME

Could the car possibly just be for show? Maybe make a few runs or passes and be fine. But for as a daily driver that you beat the siht out of, i dont think it would hold up. Especially with 440 hp.

Horsepower Peak – Ethanol E85* 270 HP @ Crank / 270 @ Crank - EstimatedTorque – Electric* 240 lb/ft @ 0 – 1500 rpm, Voltage 650 Volt Max

It's making 270hp and 240 lb/ft of torque. Thats out of the 2.5L I believe and the rest is electric. I dunno, we need more info about this but I don't see a 440hp car that has so much weight reduction only doing a 12.9 at the strip. Some people on here have gotten into the 13's without boost...

Either way, again, it's hit and miss. Daily use it will eat itself. It was never meant to take that much torque. Plus it's a hybrid, it's de-tuned from factory first of all and they made so many modifications just to get it where it is right now.

Yep...

"The race vehicle uses an electric supercharger to supplement the heavily modified drivetrain that comprises an E85-powered 2.5-liter 4-cylinder engine and an electric motor for a combined output of 440HP. According to the company, the Hot Rod Hybrid hits the quarter mile 12.9 seconds at an estimated 109.2 mph or 175km/h."

Again, there is no reason you can't boost it (tuning will be a whore btw), but if you want longevity and reliability, CVT on the 2.5 is not your way to go. Feel free to turbo it, but when it blows it's not cheap... we're talking thousands of dollars if that's the only thing you need to replace when it breaks.

lol, wow, sick exterior minus the gheyed up exhaust and wing, the rest is pretty cool.

They know something we don't. I wonder if Nissan built the hybrid transmission differently considering the immense amount of straight line torque an electric motor produces?

i think the supercharged battery is doing all the work just with a kick from the 2.5L engine!
