Wow, a 60 lbs/min turbo is GT35R territory or in that neighbourhood

That number is good for way more than 400 hp I thought? and the 0.82 exhaust aint gonna hold it back either right?
How much boost can that turbo keep and not get damaged? If its 30 psi or so, 500 hp would be very possible I would think

I hope you surprise us all when it dynos lateron

No real updates this weekend, just installed the passenger seat and seat belts, as well as the dash supports. I did get some pics of the new exhaust and camera mount though. I also installed the new race springs 300 lbs front and 550 lbs rear which cause the car to sit higher again. For now she's loaded into the trailer and waiting for her big day on wednesday.

Hope all goes well.

Use that camera mount.

Awesome!
BTW, I see now I have the same make silencer and BOV as you do

Veeeery race...good luck!!

Haven't checked in on this thread since we revived the site. You've made some good progress. Best of luck and keep up the quality work.

I know you all want to hear that the car is making crazy horsepower and pulls like a freight train but I'm afraid today wasn't my day. Got her down to the dyno and started tuning just fine until about 1.5 hours into the session. The ecu reset dumping most of our progress, losing the whole timing map and set us back at square one. The whole time we were running into wall after wall with the software (only coarse fuel adjustment, can't save the timing map that resets when you turn the car off, recalibrating tps and timing after every map save and load) so we called it after 2 hours and pushed the car back into the trailer. I'm going to make a few calls tomorrow and see what options I have but the ecu software and/or firmware has to change, or it will be replaced with the MS2 sitting next to me.

The take-aways from this excersize:
-tow rig and new trailer brake controller are awesome
-everything mechanical on the car was perfect and the oily header wrap finally stopped smoking
-once we (briefly) had a working map the motor sounded beautiful and revved very quickly
-very low vacuum (2-6 in/hg) at idle (1k-1.1k rpm) not sure if it's the cam or if there's a leak
-must add better tie down points to the bug

After working with the MSII system and seen the problems someone else had with a CB system (could have been that mechanic) I would have to say. why isn't the MSII ECU already installed

. It is a great ECU. It can control your boost, oil cooler fan, alki injection, ingition map, knock sense, it will data log and still have a couple of open ins and outs you could use for other stuff.

I'm working on a MS2 system myself, just need some injectors and to have some stuff ported and wire everything up and install it all LOL Pretty excited about it. Everyone is telling me its a crap system but I know better.

Well, you have to see it this way: good thing you found out now and not doing 130 mph

Good to hear it runs leak-free. Not many do, so, well done!

Humble · #**147** May 29th 2009, 17:06

AFter talking to Pat Downs yesterday it looks like I have an early version of the firmware and software (so much for early adoption). I'm going to update the ecu and play with it a bit but if I'm not happy I'm going to cut the connector and wire in the ms2. The main reason I haven't yet is I didn't know it worked with hei ignition, which will wire in directly with the CB kit. I'm modifying the ms2 for hei right now just in case.

kuleinc · #**148** May 29th 2009, 17:15

Awesome plan.

Well I did a little searching today and I was able to find the actual Ampseal automotive 35-pin connectors from mouser electronics. This will make the swap much much easier than originally planned and reversible. I ordered a couple sets of connectors and I'll wire one up to the relay board so I only have to plug it in to the existing harness. I updated the code in the ms2 to 2.89 and started setting up tables for the turbo motor. So now the ms2 is all set and relay board modded for the HEI ignition, all I have to do is plug them in.

Sounds like your making good progress in general, really only small hiccups, it's not like it caught fire or anything!!!

Keep up the good work.

Jason
