550 is about the limit

 

whats stopping more? bottem end?

 

Turbo isn't good for that much more I didn't think ?

 

I'd say leave the exhaust cam and get a slightly bigger inlet cam. Power etc depends on boost?

 

id say about 520 without pushing everything to the limit

 

the turbo mate

 

A GT3076HTA will break the 600bhp barrier (just) if the rest of the engine is efficient enough.

 

What is the difference in the hat to a straight forward gt3076 allowing it to make much more power?

 

From memory, the compressor wheel is a billet item which moves around 57lb of air at the top as opposed to the 52lb of a standard item.

The nut on the end of the shaft in front of the compressor wheel is modified into a 'bullet' shape, helping the flow into the extended tip of the wheel.

The bearing core is a motorsport metal caged item too on all the 30HTAs.

Gary at APT has had some really good results with them on 2.0 evo engines, here's a graph he sent me a while ago:



And guess what boost it did it at? (Power at the wheels in this one!)

 

Thats mega power for the boost

Steve

 

Great results there

 

He had 2 bd14s and lacked torque and was bloody laggy on monster T4. Changed to standard exhaust cam and made 40lb ft more. Finished on old spec at 545bhp 500lbft torque

 

So is going to see (maybe) an extra 40-50bhp lol what a waste of £7k
