THAT TOP SECRET FROM JAPAN HAVE MADE A TURBO KIT(WELL I THINK ITS STILL IN TESTING) BUT HAVE MADE 451 WHP AT 10 PSI. CHECK IT OUT ITS IN THE NEW TURBO MAG.

 

Actually, it is a pretty old mag., they are using bigger turbo's than Greddy's (as far as I know), and Greddy is making 417RWHP @ 10.29psi. They are making some good gains though. Top Secret's is still in R&D like every other turbo unfortunately. Thanks for informing anyone who didn't know though.

Actually, original article came out months ago,but the July/June Turbo Magazine has the revisted top secret article,
I guess Top Secret made some changes with exhaust , and Turbo at 10 psi top secret made 451 hp at the wheels

Now ow long will that engine last before B M

 

Greddy is only showing dynos at lower boost levels. I don't know the turbos on the Top Secret kit, but I don't see them being bigger. The 18G turbos on the Greddy kit can support 400 hp each. They are far bigger than a stock motor can hold if you want to puch them.

 

True, but they are downsizing them to the 16g (I think @ 16g). They are having to use intake restrictors to keep the boost down. I am almost positive Top Secret is using bigger turbo's otherwise they wouldn't be producing more hp than Greddy, then again Greddy has only fried a rod and Top Secret has went through 4 engine's. About the "Greddy is only showing dynos at lower boost levels." I have my sources......

 

Yops Secret is using a single Turbo setup. They couldn't find the room in the engine bay to put 2 turbos in the size they wanted. So they have just one big one. Many people have posted different rumors. Form the people I have talked to and the pictures I have seen it is a single turbo setup. They also have different intake plenum due to poor air distribution with stock intake plenum. I think front 2 cylinders get starved air. I have attached a picture of the engine. I believe some also said they have gone through 3 engines in the process and are working on piston and rods to go along with the turbo setup. Don't quote me on that.

thanks,
Greg
