if it is a good price, that is EXACTLY what i am looking for. At only 345 hp, you know the turbos are small and with 2, there will be no lag whatsoever. I remember a pic from a magazine that showed the prototype and the shroud that they put over the engine was mighty purty

Checked out a place that does some good s#*t here in SoCal and they quoted me 5100 for the kit, PRofec e-01, turbo timer, and install. I think that I can get a better deal though. what are you guys getting quoted for?

Only an increase of 50hp? My guess is from what it says that it's 345 flywheel HP and not 345 at the wheels. Is that all the stock internals can safely handle or is it the biggest turbo they could fit?

For an increase of 50hp I don't think $3k or even 5k is worth it for a FI alternative.

345 hps to the crank? or on the wheels? if that hps are to the crank, definitely it's not worth it. I think... $3K or $5K 25hps on the wheels...hum...

hold on now guys.. dont jump the gun and slam a low boost kit,
perhaps Greddy is trying to get Carb certification or keep the boost low for preventative measures..

im sure with a boost controller the turbos will be capable of higher boost, just that greddy will not be liable for any boost higher than their posted limit, nor will the fuel system handle the extra boost i think..


as for the June Time frame, wow. thats great..


i hope other companies will come out with their kit at similar release dates.

actually,

they wont release it until carb exemption is certified... dont know how long until this happens...

and more importantly:

they are running low boost, cause they are not retarding timing at all. this is because their ignition harness for the e-manage will fry the stock ignition coils... these coils are extremely sensitive to stock dwell and timing on decel and engine start-up.

this brings up a couple options:

get the kit as is, and enjoy 5lbs of boost.

or

get the kit, and add something to retard timing (with a built in retard, and boost based retard, and also tie into a knock sensor for detonation sensitive retard) this would be accomplished by a 4 channel direct ignition UltraSafeguard

or

get the kit (or have a custom one built) and replace the e-manage functions with something like, hmmmm, like a motec 48 stand alone ECU? (a safeguard is still recommended for those "untunable" situations like bad gas, etc...)

how about your Stock ECU tuned, with a Force Induction program that will retard the engine at all the key times?
Untunable situations can be taken care of, especially with the built in knock sensor that will alter the fuel by itself.. which really wont be altered with the tuned ECU program...


wink wink.

it's definately at the wheels. Do you think they would pull the engine to get a crank hp reading? I think not. Plus, if it were 345 crank hp with 5 lb of boost i would find that very unbelievable. Trust me, it's at the wheels.

Can someone call and confirm this??? If it's 345 at the wheels, I'll order mine today! That's like 425 or so hp at the flywheel... a 50% gain over stock!!!!!!!

I think it's 345 at crank, cuz it only hit .45 bar of boost pressure.

I think it is 345 HP at the wheels.

If you do the conversion of .45 bar to English units, that's an increase of 6.4 psi. Atmospheric pressure should be around 14.7 psi, so that's about a 143% increase in pressure, and all things equal, 143% more oxygen.

143% of 240 HP is roughly 343 HP. I don't know much about forced induction systems, but if I had to guess, that is how the pressure relates to HP. It makes sense anyway (to me).

Your math works out, if that's how it equates then you are pretty good

nope, that is not how you look at it. I am not able to explain detail here. However, because the air flow volume, size of the turbo and A/F ratio play big role here. So you don't just take number and calculate it like that.

anyway I will call greddy tommorrow, and see what's going on.
