402whp @18psi 3hours of tuning so we are thinking 420whp with not being heat soaked are these good numbers or no? Supporting mods are Magnus Intake manifold, AMS Exhaust Manifold, 50 Trim Turbo built by us W/ stage three wheel, Custom intercooler piping made by us w/ battery relocated in trunk, 880cc injectors, 280 comp cams, 255 walboro fuel pump, hallman MBC, Aftermarket frontmount, 3" TBE, HKS BOV and timimg belt, ARP headstuds.

 

It sounds like good numbers to me what psi is this at

 

how come only 18 psi- but whp sounds right

 

need more boost man

 

What do you mean by stage 3 wheel?

 

402awhp @ 18psi, that's stout

 

that pretty good.

 

Dam i missed it 18 psi yea then that is good for that psi. Turn it up if u want more power

 

hallman MBC will not hold boost pressure it spikes 23.99 real low in the rpm range but when it made its power it held 18.24 psi. she wants to get a greddy profec b boost controller then we hope 24psi will be 450whp to 470whp tuned by JK TUNING which is her brother.

 

it is a turbonetics satge 3 wheel her dad build it himself we have done all the work ourselves on the car an if you know anyone who would cams or 19" wheels please let us know

 

hallman is ball bearing so make sure its mounted in the upright position- also what wastegate spring are u running- i was able to spike 28psi and hold 24.xx at redline with stock 9 turbo w/20g wheel using a hallman

 

But my concern is it still drops off if she gets a ecb she will hold the boost no problem.

 

I hold 25psi to 7,000, 2.3 50t no problem with my hallman.

 

street racing video = a big negative on evom

 

mine hallman spikes 24psi and holds 21 till redline, kmaybe you should change out your mbc spring
