Want to keep it mainly bolt ons , and be my daily as well.

Pump gas or E85?

Regardless you can't go wrong with a FP 71hta

 

Fp red
Gsc s2
E85

 

On Pump Gas

 

From what I have read/seen, you can get close to, or exceed 400 whp on just an 71hta and pump, which is a bargin.

E would get you closer to 450.

 

Im always looking for something a little bigger so i can always add more fuel and get bigger gains, Why not think a PTE5858?

 

blouch 1.0xt/xtr

 

 

FP SS Green? Do you have dyno chart so we can see how well it spools?

 

 

You guys are lucky to have 93 octane. 26 psi and hitting 400whp is nice. That SS housing really slows spool quite a bit from the MHI. It looks like 4600 rpm before you see 300ft-lbs of torque.

 

...pump gas, yo.

 

Yes, but Green MHI should be seeing 300 ft-lb around 4200 rpm. This is my 71hta for reference. This SS Green looks laggier than MHI Red even.

 

It's hard to compare different turbos and setups. Plus he said "external wastegate", so I assume it's a SS housing which = about as laggy as MHI Red. Plus, we don't know certain details of the rest of his build. Sounds about right to me.

 

Correct. The SS Green looks laggier than MHI Red. I'm thinking OP has a boost leak somewhere.
Oh wait, no mivec here. Is this normal lag then?
