Nice times.

I know she has more left in her. I was able to trap 126 on a bolt on 8 blade at 30psi with e85. Your setup is very nice and I dream of it every now and then. Lets see a 9 out of this thing and I would love to see some more video. Nice work and keep us posted.

32-33 psi, 1.49 60'

mph was a little lower than expected but only got one run since I broke the front yoke the next pass. (except for the FWD pass after I dropped the driveshaft )

Well even though the mph may be lower there still seem to be more positives vs negatives using the automatic transmission even more impressive a stock automatic tranny.Keep up the good work,impressive none the less!

Updated info and times later in this thread http://www.dsmtuners.com/forums/drag-strip/450069-hx35-10-3-a.html

With the 5 speed I'm pretty sure I'd be in the upper 130 range since it went 135.9 on 30 psi a while back. I'm going through the traps at 8500ish rpm with the auto which I'm sure kills the mph. The 1/8th mph was 107 that pass and I think the best on the 5spd was 105? Either way it gets it done where it counts

Crazy.

Nice job matt!

Was really awesome to see this car in person!! Nice times and keep up the great work!

iam in love

Wow great run

I've been going over ideas in my head for getting more consistent launches and be able to dial it in more, and I think I have an elegant solution.

First off, the fuel cut two step kinda sucks on an auto. Controlling it by the brake switch instead of the VSS helped a lot, but the set rpm increments don't offer enough tune-ability(250rpm). Even if that was fixed, the low launch rpm causes a slow cycling of the limiter, making rpm bounce around a hundred rpm or so which makes boost bounce around by 5psi or more when I'm set up for drag radials. This makes it inconsistent, and more likely to break parts when I don't know if it will leave at 15 or 20 psi.

I wanted to initially use something that functioned like a wastegate on the upper IC piping so I could have the car psi limited at the line instead of controlling rpm. I was going to make something, but it seems like the stock 1g bov works extremely well as a wastegate when you block the top port.

My BOV is already dodge garage modded so I have the bottom port open to atmosphere through a tube on the side. I have a bleeder style MBC going to the bottom port already so I can adjust how much psi the bottom port sees so I can find a good balance between stock quick response/surge and holding boost.

Because of this, all I would really have to do is adjust the bottom port MBC to where it starts leaking and stops building boost while the upper port is blocked off by a solenoid. Did some testing and it goes right up to 6 psi and stays there with the bottom port MBC set all the way down, which equals out to about 2800rpm with timing at 0BTDC(tied into brake switch). It is obviously higher with normal timing(~3100), but the whole point is to leave at a lower rpm with the same boost. I turned the BOV MBC all the way tight so the bottom port is almost completely blocked off, and it shot to almost 25 psi before I let off. Oops This means the there is enough adjust ability in there to leave at the perfect boost level for whatever tire I'm running.

I will run a universal speedometer cable from the bottom port BOV MBC to the center console so I can finely adjust launch psi in cabin. The solenoid will block the BOV line and probably open the top port to atmosphere(may need another solenoid) so there isn't any residual pressure or vacuum. The solenoid will be wired into the brake switch so it only closes when the brake is pressed. My base timing retard will be switched on by the brake switch still, but I may have it automatically triggered after 3000rpm so everything is automatic(I have an override switch by my leg right now I flip on right before it hits launch rpm). Once the brake pedal is released, timing comes back in and the solenoid will open back up applying full pressure to the top port to close the leak and let boost ramp in. I see this ramping boost in quicker than by wastegate, since the turbo will be spinning a little faster with the leak and the wastegate will already be fully closed.

It's going to be a long winter until I get to try it out at the track but I see good things

A little update:

Got a new personal best, 10.09@132 1.425 60'

The car as it sits-

~33psi(didn't log just glanced at gauge)
Twin scroll hx35 still
6 bolt rods/2g pistons
2g head 272/272

Stock convertor
Kiggly flexplate(stock one cracked horribly)
1g trans refreshed with 5 pc kiggly front clutch
"blue wire mod" set at 5 psi
shift kit, much better 3rd gear shift

evo8 suspension, had to run coilover sleeves up front so the M/H didn't rub the spring perch at speed
Limiter straps in the front 3/8" slack.

255 in tank and inline
Jackal
4 bar
1250's

Best time on street tires was at the shootout, 10.5@128 with a 1.59 60'

She is moving! I like the ingenuity with your entire setup. Probably a little too much adjustment involved to perfect it, but that's about the only way to perfection.

Congrats!
That is awesome. Love this setup, feels old school DSMer like.

It may be time for an update from the dead!

My wife, Samantha, and I started Morrison Fabrication and Design. In that, we had the torch passed on to us from Ron to continue making the DSM and Evo side of things from Shearer Fabrications! Of course we had some other things cooking as well and the twin scroll T3 manifold is one of them

Thank you for all the support!

Looks very nice. You've came a long ways since the mild steel mig welded one! Where do the nice transitions from the port to 1.25 come from?

Thank you!! Very glad to see you are still on here!

AceRace offers some 1-1/2 to 1-1/4 NPS transitions and some are our own making when those don't quite work out
