max horse power?
 
anyone know on a ballpark average whats the most HP you can get an svx while still staying n/a??:rolleyes:

Whatever that number is at the moment... I predict it to be quite a bit higher a year from now.

Hmmm...The only mod I've seen which is dyno proven to add HP to an N/A engine is that new intake. At the crank it's probably good for about 25 HP, putting a perfectly running SVX in the 255 crank HP ballpark. Plus cams, those fancy spacers, big exhaust, ECUTune chip, port/polish...I'd say you could see 270 crank N/A.

I think those dyno figures you saw already included modified cams, so it was not a true intake improvement measurement. Of course, maybe I read it wrong.

190-200whp is a plausible goal using the parts currently available and the knowledge too.

The car did have cams, but there was as dyno run without the intake before the run with the intake. The intake itself made a good improvement, but there is no evidence a car with stock cams will see as much of an improvement if any, though I am optimistic it will.

my old 5mt dynoed at 191awhp... Thats the best SVX to date n/a

what about converting to rwd and 6 speed, remove any useless parts that were used for awd and then could u see even more hp? ive heard awd can really hurt hp after u get up and go.....

jeffast 11-07-2007 12:15 AM

i don't know try it and tell us what happens

Of course there'll be more drivetrain loss with AWD than RWD or FWD. But switching the SVX to FWD or RWD would be silly. Yes you would get more torque. Yes you might see some more WHP. But you'd be giving up driveability. RWD more so than FWD.

I don't get why HP would be all that important for you, to the point of giving up the stability of the AWD. It's just a number. I'd rather gauge it on how well the car responds the way I want it to. And I can pretty much guarantee that switching the RWD would completely kill that notion.

About what kind of Shaft HP would that translate to? and what Mods were made to get that HP?

depends on the cubic dollars you want to spend on it.

you want to spend the money to get a power peak at 9K rpm, you can get it.

Getting a power peak at high rpm = lots of HP

thats a large pile of money so... have fun.

TomsSVX 11-07-2007 04:54 AM

it was after I sold it it but I think it peaked at around 5500 or 6k.

You would need to figure about 25% parasitic loss with the 5mt so probably around 260crank hp.

now i know the nissan 240's can easily drift.... but can the svx drift with rwd while still being n/a?? considering it ways ALOT more :lol:, i raced a 1990 240sx, sr20 swap and had 8 pounds of boost, had him off the line and all of a sudden i got smocked!!!!! :o
