So got my turbo back from WorkTurbochargers after inspection. Reed said everything looked perfect - and I'm using Rotella 15-40. He upgraded one of the bearings and lathed down the housing to fit in a 60 trim compressor wheel. If y'all need ANY turbos rebuilt, you need to give Reed a call! Check out his site.
Instead of putting it on the dyno, my tuner Eric Hux (huxracing - since I don't know **** about tuning) is going to tune the MS while on track in 2 weeks. We're running the MS on the MAP sensor, so if anything it'll running a little lean - he had some issue with the LC1 resetting last time that made it useless when connected to the MS. We'll take another look at it this time, but we'll be using his LC1 box-a-jiggy to get logged A/Rs.

Anyway, thread useless without pics! ARTech's taco clone worked perfectly - no re-worky down pipe... TSE's 10mm Inconel studs with Stage 8 fasteners







And an OEM cover I picked for $65

Well - after the increase in trim, went and retuned the car. Thought it'd be MUCH better to see some feedback on the dyno than just tuning on track. Saw a couple runs peak at 280rwhp and 254tq but not together. Had an issue with the gate spring not staying put - too much backpressure forcing the gate open and couldn't get past 18.5psi. So we regulated 6psi air behind the diaphram to add - well, another 6lbs spring force which let us hit the 20psi I was looking for.

We still have some more tuning to do, but this is where we stopped today... still bangin away on the stock 1.6
Also, at 21lbs I was maxing out the supra injectors - 95% duty cycle

This was at 20psi

I assume this is a dual port actuator- how are you regulating the backside pressure on the diaphragm?

Stout work for a stock 1.6!

Please tell me you are coming to Road Atlanta Dec 3-4! You've got to.

It is - it's a 38mm TurboSmart. Eric had a very nice regulator he put on his air hose. To test, he connected the output of the regulator to his MAP sensor connected to the computer and dialed the regulator to 6psi, then locked it in position so it didn't move at all during a run. We connected it to the back side of the diaphram (where the spring is). We re-checked the output psi to make sure it didn't creep. That was the only way we were able to hit 21 psi (we dialed it down after) which confirmed our thoughts that the spring wasn't keeping the gate closed at about 18psi. It had a 10# spring in it, waiting on the replacement. I once inadvertently connected the boost control hose from the solenoid to the backside port - man - hit boost cut almost instantly and the car bucked like a bronco. It didn't take me long to learn the different between the 2 ports and which one to connect to the solenoid!

Hey Six - sure looking forward to it! I haven't registered yet, but don't see where it'll be a problem.

Had a blast this weekend at Barber with ReZoom Motorsports. NOTHING FAILED! Didn't throw a rod through the block, the ARTech manifold held up, the TSE studs and stage 8 fasteners didn't loosen, didn't have fuel starvation issues - ran the tank to E - in all I was beat to hell by the end of the weekend. sbrian2's wife did awesome on track - she was gtg after the 3rd session when she started passing the vettes and porsches in the same run group!

The best time I had was with this supercharged elise - we were courtious to each other for lead opportunities but man - we were neck to neck. He might have had some better torque out of the corners, but I think I had a slight edge on the top end... here's the videos! If you time them right, you can watch both at the same time (mine starts at 23sec to his start). More to come -



From his angle

Awesome vids (as usual). Bet it feels nice to have a weekend w/o issues and 100% focus for driving. Were you running 20psi at barber?

It was nice to meet you, and i as well had a great weekend. Glad your car held together for both days of fun. For me back to the drawing board on a few things

Awesome vids and thanks again for instructing Tara.

I can't wait to get back there in the spring with hopefully better suspension on the car. I think next time we will each run one day so we can really focus and make sure we both get more track time and give the car more time to cool off between sessions. The tires and brakes were really getting iffy after back to back sessions.

Glad to hear your car did well all weekend. It looks like a total blast out on the track.

Your welcome Brian - next year, ReZoom may be at Barber 3 times, which would be sweet!

Took about 7 people for their first taste of what Barber is like... I need to tell them to leave the phones in their car, lest they fly out of the window
Here's making a buddy squirm like a girl - and I spin it out of T5 and luckily didn't hit the wall - which from the angle I just got lucky, not a save in any stretch... guess the spin made him sick But on a side note, that afternoon he scored an '84 944 (in GREAT shape) for $250 and plans on tracking it - another one hooked



And this one is taking Raymond on track for the 1st time.

Sucks...wish I could have been there.

On the plus side, I did finish my first 5k with a not-terrible time of 29:40.

You need to add a turbo up your *** to help step that pass a little! Just kiddin - yeah, you missed a good one, but there will be next year!

Looks like you had a hell of a time! I hate I had to miss out, we are in engineering trials still for the new M class and weekends have been few and far inbetween.

Charging the tires with N2 - being a refrigeration contractor has it's little perks sometimes...

Pulling vaccum then charging to 25# Nitrogen



- also have a 3.63 R&P on order thanks to a MT member here

That R&P should put you at 148mph for the rd. atlanta's T10 braking zone.

Wheeee!!!


And by Friday I'll have this in the mail to tell me so for the coming Nasa event at RA! Coming Jan, this will be able to sync with the GoproHD



I highly doubt the 3.6 will be installed before then, but there's always NOLA if I can swing it - otherwise next spring

And you'll be getting 32mpg on the road trips to and from the track.
