Damn that anodizing came out perfect! !!!

Keep getting weight out of the car so that smaller turbo you got might go as quick/fast as before! :cheer::cheer:

Re: Mark's 1G Winter Projects
 

Update on what I’ve been up to lately. I have my $$$ sfi 15 Simpson fire suit now, Brainard enforces you to have one if you burn ethanol and run a turbo car quicker than 9.99.

I wanted a detachable steering wheel to make entry and exit of the car easier for safety and comfort. Searching was not easy, lots of misleading information from suppliers and forums. I also found out that NHRA requires SFI certified detach mechanisms and wheels. I didn't want to just replace the wheel, as I also realized that there was a weight savings opportunity. It ended up at 19 lbs for $250.00! I found the wheel here: http://www.dragzine.com/news/new-pro...m-quarter-max/
The sfi detach mechanism is from Stange. The wheel and detach are under 2 lbs!. I used 4130 ¾” shaft and turned an adaptor on my lathe out of 1018 material.

I need to get an alignment and some fresh e98. I'll be going to rock falls April 23rd.

I also improved the intercooler piping entry angle into the throttle body. It required me to build a new overflow tank too. It's all optimized now!

Re: Mark's 1G Winter Projects
 

So nice! I need to see this car in person sometime.

Re: Mark's 1G Winter Projects
 

Nice on the wheel, curious why you need an alignment though because of the wheel. Or is it because of the other suspension mods you did? It didn't take much to learn how to do a string alignment and I found it very rewarding if you're willing to put in a few hours, good luck this year!

Re: Mark's 1G Winter Projects
 

Love it.

Re: Mark's 1G Winter Projects
 

The reason is the rear end is way out of alignment, with the old mustache bar bending it took the rear out of alignment. Thanks for the luck this year. I'm anticipating a very fun, fast, and reliable year!

Re: Mark's 1G Winter Projects
 

I just need to get some fresh e98 and an alignment and I'm ready for a test and tune. Rock Falls has a session April 23rd and I plan on being there.

I started the car last weekend and drove it around the block. So far the turbo seems to out spool my old setup, however the data is a little bit premature to claim victory. I'll know more on the 23rd.

I twist splines on every yoke I use. I was concerned about movement in and out of the transfer case when I went to the one piece driveshaft, so I found a forged yoke. Mondale pointed it out for me.

This one shouldn't twist the quality is awesome.

I also added a emergency stop on the dash that's connected into the safety battery disconnect.

Re: Mark's 1G Winter Projects
 

Industrial style EStop, nice touch :)

Re: Mark's 1G Winter Projects
 

do you have a t case brace?
They seem to stop twisting/side shifting of the t case issues.

Re: Mark's 1G Winter Projects
 

Oh dat yoke doe!!!
sexy

Re: Mark's 1G Winter Projects
 

The last trip to the track wasn't very fruitful. My clutch slipped and banged off of the rev limiter under lots of boost. It blew the head gasket. I also found out that my drive shaft has harmonics issues. And I inspected the head I found it bent all the exhaust valves.

It's been a busy month:

I remove the single piece driveshaft and sent it back to DSS so they could turn my one piece shaft into a two piece.

They did an awesome job, and barely charged me anything to split the shaft.

I sent the cutch back to tilton, I figured out I had a setup issue that caused the diaphragm spring in the pressure plate to slowly lose its clamping force. That's all fixed now.

I remove the mechanical water pump and converted to an electric and I'm now running waterless coolant. I drove it on the very hot weekend on the freeway and it stayed cool.

Special Thanks goes out to MAPerformance, Eric rebuilt the cylinder head with meticulous detail. Also thanks goes out to the whole crew that help me out while on the dyno, Jake helped me strap it all down securely. I blew an intercooler weld on my ets unit and Tim help me weld it up. I ran 4 pulls, the first 2 were partial pulls. The last pull is below, ignore the dyno wide band reading.

The boost peaked at 50 and dropped to 48psi. With a safe 11.6 afr.

This weekend should be awesome!

Re: Mark's 1G Winter Projects
 

Woot woot! Glad it worked out for you today, I can't wait for the weekend!

Re: Mark's 1G Winter Projects
 

Wow that's awesome power. Curious why you had vibration issues with the one piece driveshaft, was it because of the angle? I don't know much about DS technology.

I've heard great things about the waterless coolant. Expensive, but nothing compared to the cost of a race car setup. I'm surprised it ran cool, most say it runs hotter on the street, but since it doesn't boil it actually takes more heat away from the motor at very high temps, which is great for the track.

Re: Mark's 1G Winter Projects
 

Congrats!
Good luck this weekend!

Re: Mark's 1G Winter Projects
 

I'm no driveshaft expert either. I know a little bit about harmonics and the frequency domain from my engineering experiences.

The symptom I experienced was a bad vibration while slowing down between 105 to 100 mph. Otherwise no issues on acceleration. I spoke with an engineer at DSS and it doesn't violate critical speeds, but weird harmonics can happen when you have high durometer poly mounts on the engine and rear end, or if they are hard mounted.

Now it is silky smooth with 2 pieces.

Re: Mark's 1G Winter Projects
 

Very cool, congrats on the numbers!

Re: Mark's 1G Winter Projects
 

Awesome! Can't wait to see it this weekend!

Re: Mark's 1G Winter Projects
 

Almost 1,100 AWHP, not bad for a 4 cylinder! Car has come a long ways, good work Mark.

Re: Mark's 1G Winter Projects
 

How'd you end up doing at Show n Go? I never seen you again after Friday!
