Thanks guys. The car is on Dsmlink but don't have the logs. The restrictor is a .93 or so. But I've been having oiling issues so hopefully this works now. My 1600s and 2 bosch 044s seem to be about maxed out at high boost but enough to run it.

Not to discredit nearly 700whp from this turbo, but 573lb/ft of torque? That is completely ridiculous! Usually at some point your torque numbers start to suffer when you switch to a large-airflow turbo because the powerband is located so close to (or even later than) 5250.

Think of it this way- this setup probably reaches full boost around 4500; maximum torque is extracted around 5250. So in that 700rpm window, nearly 600 lb/ft of torque happens.....really quick.

These HX40's are making retarded-high torque numbers. We have dacowgod at 521tq, turbodsm18 at 527tq, richard33 at 573tq, and badman21 with 618tq. Unreal.


Great work, Richard. Looking forward to the ported head results!

Here are some pics. The videos are taking a while to load.


This is a crappy cell phone pic of the dyno graph. Red was the 682 pull and blue was the 649 pull


My fuel setup


And what the car looks like today

haha I don't think the head is coming off the car soon. I have to get my throttle body rebuilt and then some suspension stuff first.

Thanks again for all the help and taking the time to respond to my pms these last few days!

Just noticed in the vid- did you dyno with the QTP's on the front? I've always heard that slicks on a dyno can fog your results a little.

Ya I did. These aren't slicks these are my street tires lol. I ran them at 25psi so I don't know how much different the dyno reading would be. They didn't spin or anything. Are they supposed to increase or hurt the #'s? I've never heard anything like that honestly.

That's F**king sick man, I just installed my HX-40 last weekend and love it even though I'm running only 10psi. There's a 8-blade HX-40 right ? I read somewhere on here about a super 40.

The numbers might not be off so much at that pressure. Iirc it's the expansion and 'give' in the sidewalls of slicks that fudge the numbers.

I've always understood that the horsepower number would be higher from harder rubber- like the soft sidewalls of the slicks "absorb" some of power the wheels are putting to the rollers. I could be wrong, though....it would be interesting if someone did back-to-back pulls with street tires, identical tune, and see what changes and by how much.

Yes there is an 8 blade but the 8 blade is the bottom of the barrel of the HX40s. The Super/Pros are the 6 and 7 blade versions with the 7 blade billet being the best of the best as far as the HX40s are concerened. Badass turbos for sure! Me and Justin are going to forcefeed one to Lucas at English racing and see what he can do with it..

Haha I'm at that track now running an 11.5 pass. First elimination pass I wet 11.7@107 lifting up top cause I was out in front. This is on low boost 25-28lbs to keep it slower than 11.5.

edit- ended up getting knocked out in the semifinals. I went 11.55@132 but the guy had a better reaction time so he won with an 11.7. It was a lot of fun though for my first event. My 3 elimination passes for the 11.5 class were 11.7,11.7,11.5 so I did pretty well just need to work on the pro tree a little bit.

Car went a best of 10.9 and best mph 140. Hx40 survived another night of racing, guess its ok to increase the boost back to what it was on the dyno.

haha thanks for towing the car and videoing!


Overall Im happy with the car getting faster but think there is more in both the ET and MPH. Being FWD I have to run low boost in 1st and 2nd gear. I need to start focusing on the suspension a little bit to leave harder.


Here is a little better pick of the dyno sheet


The time slips from tonight..
