what is done to his block to be able to handle that kind of power?

 

Its was orginally a 2 bolt block, then converted to splayed 4 bolts.

Jose

 

is it filled or hard blocked or anything?

 

According to the owner it was not modified anymore then the above mentioned. Of course he has not been running it for long, so we will see how long it will hold up in its current state.

is that pretty much maxed out? damn, thats alot of power for a 76mm turbo!

 

and how the hell did it pick up 130+ rwhp from just a few #'s of boost? thats awesome!!!

 

I was estimating around 850rwhp could be more, but with a good setup 4-5 lbs makes a good bit of difference. As for maxed out, yes, he said the boost was starting to drop off in the higher rpms. Which is typically a sign of a turbo that just can't supply any more air. I am though furnishing him with my PTE88 and my Downpipe to test with. Should be interesting to see what the kit can put down with that turbo, if the rest of the parts can hold up.

sounds interesting!
