On the intercooler issue APS engineers have decided to replace the stock fascia/bumper with a new bumper with a much larger frontal opening as they have serious concerns regarding engine cooling at approx 350 to 400 WHP, particularly in high ambient conditions.
This new front bumper will allow much greater air flow to both the huge air to air intercoler and engine radiator, ensuring that the engine temperature is safe under full load high Horsepower operating conditions.
Imho one very large bar and plate style intercooler with internal and external finning which provides very low pressure drop across the entire intercooler system with a huge reduction in charge air temperature is the optimum intercooling solution for the G35.
It's my view that the more efficient the intercooling the greater chance to avoid engine detonation if the fuel octane ever drops off, and higher more reliable Horsepower can be generated by the colder more dense air, all good.
Thanks

They use a state of the art Garrett twin ball-bearing turbos. You will probably not have as smooth and stock-like torque curve as with the TT. But, I would bet that it will not be a real issue, and may be a worthwhile tradeoff for the $2000+ savings.

The APS single turbo system does have particularly impressive low to mid rpm grunt (both power and torque).
APS engineers have spent a considerable amount of time matching the single GT series dual ball bearing water cooled tubocharger to the VQ engine, combine this awesome turbo with a 10:1 static compression ratio and short smooth flowing exhaust manifolding and the engine performance (instant engine response) is really amazing.

Your correct Gurgen, the low to mid range torque of the APS single turbo system is really the significant benefit of the single turbo over to a Centrifugal SC, I'd say it's like comparing 6 psi boost at 3000 rpm for the single turbo compared to approx 3 psi from the SC, you can really feel this additional power on the road.
Gurgen you are one of the very first true pioneers who went down the TT path, you should be congratulated for all of the wonderful assistance and advise you provide to others who are following in your path, well done my friend, hope to catch up with you soon.

So 5.7k to 5.8k for the WHOLE kit???
Then a few hundred for a new front bumper...
then a lot of cash to have the bumper painted, installed....then the turbo kit ahs to be installed...
So for about 7k you can have this kit???? does this sound correct? Am i forgetting anything???
Are there any other options for serious power for cheaper???
OHHHH, and MOST Importantly....how loud will the BOV be??? hahaha

The priority and total focus for the moment is the G35 Twin Turbo system, the testing should be completed by the end of March if all goes to plan .
Development and testing will then start on the single turbo system to suit the G35, if this proves to work as well as the APS single turbo for the Z car then I think it's very possible that a single turbo system will be released for the G35, I certainly hope so.
Thanks
Peter

Not out yet for G, but the TT has been out for 350z since Nov/Dec. Alot of hype, praises and good results/#s from my350z.com forum. APS has not yet confirmed if they will design a ST for G only the 350z. TT for G to be released May or June.
