Need some more tuning and injectors should be able to hit 400 with some tuning. real rich up top.

 

forgot to upload pic.

spec
13brew small street port on intake only
4 850cc with 1500cc meth 2 walbro pumps
holset he351ve vgt turbo at 18psi

 

What are you using to control the VGT?

 

It is very simple a small spring lol. Back pressure does the rest. The more pressure the further they open. Car is super quiet on low load driving then vanes open it get louder.

 

Dynojet numbers add 10-20% compared to a mustang or dynapak, but still quite impressive.

could you upload some pics of your setup and the vgt spring? I have one of those turbos sitting around but thought a wastegate actuator running the vgt would cause boost to spike too violently. The spring would be a fair compromise.

 

small exhaust ports FTW.
I dynoed 361whp 309ft-lbs on cleaned up stock ports, on a S5 TII engine and S5 hybrid turbo with 2.5" DP

 

Go back and clean up your map some, I would love to see a sheet after some more tuning. That think already shows and awesome torque band.
