Both runs on BP 93 see video for more details.

Forgive me if this is an obvious question but... Looking at the HP numbers between pull 1 and 2 I'm confused. If I'm reading that right, your boost went up 2.5psi but your max HP went down 57?

KVandy15

I added MHI Turbo, injectors, pump, and tubular manifold between 2 and 1. Map 2 is from a couple of years ago, same tuner and dyno so he had my old graph handy. MHI Turbo is bonkers, best upgrade I've done yet. That boost "Curve", much flat, very boost. Hp curve super linear all the way out, feels great on the road.

Out of curiosity, why aren't you running higher boost on the MHI? I have a 2012 GSR X on the MHI and I'm running 26 to get 385/320 on a mustang dyno, or thereabouts, on stock block. Seems like you could get there too with ~4 more pounds of boost. Is it more for the SST tranny's safety?

Regardless, your improvement towards redline is huge vs stock turbo. Good stuff.

haha.

Just being conservative TBH, it's a daily and I was already pretty happy with the results so we decided not to push the boost any higher for now. I'd be fine with making ~26 in the mid range (obviously did on the old map), making 26 out to redline makes me nervous. Also I've got a flex sensor and I am actively waiting for TephraModV3 to come out for my rom. When that happens I'll revisit on E85 and maybe push the boost a bit more at that point.

nice numbers.. this is on stock IC ?

KVandy15

Nope, cheapo 3.5" IC from Depo Racing. End of video has all mods listed out and some more details.

thanks.. I am just building a SST evo X for a friend with very similar spec... MHI allready on, and now have to install the pump, injectors and the IC..

That makes a lot of sense. Chart looks really good. I'm slowly replacing the turbo on my Evo with this same one. My goal is to hit 400 on pump 93. I love how streetable the car is and don't want to have the "Where do I get e85 around here" moment.

With a GSR, 400whp on pump 93 should be no problem with the MHI.
*edit, noticed you have an MR.

I'm currently trying to hit 400 with my MR, same turbo, on pump 91. last dyno result was 391, so I'm almost there!
*edit, I just hit 401/336 on my MR on 91 :3

I need an mhi 18k in my life

KVandy15

No arguments from me. 3 Months in and I'm still super happy with it.

What did you do to get 401/336 (Dynojet ?) from your MR with the MHI 18K? Cams and/or manifold?

Never mind, I saw your post - sorry about your engine failure.

At 22 psi the setup is definitely conservative, as long as you have the fuel system capacity to get 11.5 AFR to redline it's really no big deal to run 26 psi to redline on that turbo. My 20g compressor upgrade holds 26 until 6k and then drops to 25 psi @ 6.5k and 24 psi @ 7k which means I'm running it a bit hard. The MHI in general tends to have lower torque in comparison which is good for the MR and stock blocks, but holds boost efficiently to redline so you get less torque drop off and higher horsepower numbers as a result. E85 is also a very nice way to further improve top end power with low risk if dialed in correctly. You can keep torque in check in the low RPM range and then only ramp up timing as rpm's rise.
