1G 5 speed - Sick of 9's...

You can get a launch control device at MAP:

MAP Hydraulic Launch Control Device for Manual Transmission Vehicles - Modern Automotive Performance

The launch control device has an electric controlled hydraulic solenoid and a flow control valve.

The launch control device installs in line with the hydraulic clutch system. I use all an3 fittings between the stock clutch master cylinder and launch control device and the other end goes out of the launch control device to the clutch slave cylinder.

How it works: You disengage the clutch, put your foot to the floor. Then activate the launch control device, with either an electrical switch or have an ECU control it on something like 2-step rev control. The electric solenoid that is activated blocks the fluid path. This will force the fluid through the flow control valve, causing a controlled clutch engagement. The effect is that it will control the speed at which the clutch is engaged when you let the clutch pedal out.

Or get the real one and not some knock off sold link up top

How do you like those vibrant clamshell clamps? Im really thinking about getting some for my build because I will be running about 40psi on my hx40 and dont wanted to deal with boost leaks, constantly tightening clamps and the possibility of crushing my I/C piping by over tightening my t-bolt clamps

Not a fan...We have been replacing them left and right at the shop.

I wouldn't be getting so hot an bothered about this. Ideas like this have been around fooooorrreeeevvvvaaaaaar.

You should as they have been using a cheaper one that fails. but do whatever you want with your money

 

[Spdfreak]

no. It only messes with the clutch.
Its for a manual transmission if you didnt notice.

Yeah I'm totally aware it's a manual, just trying to find out if he is still using his staging brake to preload the drivetrain before launching the car or just letting the clutch device slip the clutch for him.

Have you been seeing failures on MAP's launch control device specifically? What parts are different / inferior in the MAP one compared to the Magnus one?

I have had very good luck with the vibrant clamps for some time now at 40+ psi. I have had to replace a few of the orings on the pipes, but that was as much my carelessness while slipping the sleeve over them as it was them being worn out.

You provide no value to this thread. There is nothing novel about the launch device, your 100% incorrect about your statement regarding it. Magnus didn't develope/design it in the first place. Magnus makes novel products like the v3 intake manifold, that I use and think is awesome.

Keep your ratchet bs out of the thread.

With the launch control device do you still need the staging brake to preload the drivetrain?

Yes I still will use the staging brake to preload the drivetrain. I'm excited to try it out! I will be getting out in late may. But running on the street a little to test it all out prior to the track.

Thanks for the diplomatic factual approach, unfortunitly its not worth it sometimes.

Ok cool that sounds good, can't wait to hear how it works out for you.

Had a good weekend at BIR. I started to tune in the launch control device, it works well but is very touchy. I need more seat time as I only got 5 passes in all weekend. The car is ready for the MAP event in June. I was able to focus on the tree cutting a .047, .098 and a .2 second light. This video was during time trials and the mustang ran a 12.0, you cannot see it from the video.

I was going 124.9mph, 6.03 seconds in the 1/8. This was a 1.60 60 foot too! I rolled the beams causing a slow 60 foot time. I know how to solve this too.

Overall a fun weekend.

 

[GRAVEDIGGER]

Wow Mark, nice run! The car looks and sounds great and shows lots of promise with those numbers. Keep up the good work!

 

[airmail96]

Jesus christ it looked like a rocket ship taking off.

 

[Spdfreak]

Congrats on the nice run. I knew this car would be a beast, It's got 8s written all over it.

 

[Sheldon7]

I think the replacement for displacement is DSM. That mustang was sweet but no match! Nice build. looks, sounds, performs beautiful! Wouldn't mind seeing more pictures! 2 thumbs

I'm up at MAPerfromance's 2014.1 prooving grounds. I bogged my first launch so I aborted the run, second pass I ran a 8.91! No longer sick of 9's ! The car is running great and qualification rounds are today. I'll load up a video next week after the event is over.

 

[GRAVEDIGGER]

Nice Mark!!! Great 60' time, awesome 1/8th et and mph, and even better at the big end with an 8.9 @ 162! I can't wait to see the vids.

 

[Mark L]

My fastest pass to date, the weekend went great over all.
This video is of the 8.86. It was prior to the elimination round. I figured I needed to face the Toyota, since I would be seeing him in the finals. I’m 100% happy that I got out first!!!!!!

 

[u2slow]

Nice pass!! Congrats. I`m sure you had a handful, but not like the other driver.

 

[GRAVEDIGGER]

Awesome job man! Damn, I can't believe the driver of that Toyota was able to save it. That thing was just dying to kiss the wall.

Quick update:

I’m in the process of building my aluminum rod 2.2 SLR motor. I’m using a 6 bolt Eagle 94mm crank with R&R 153mm rods. I didn’t know how well the clearancing was going to go, since others have had major levels of work to get a 2.3L to work with aluminum rods. I finished up the block and it clearance just fine with no issues blowing through the oil galley! These rods are huge too! Check out this thing next to my factory Evo IX rod!

This was during the clearancing process, the girdle didn't even need to be modified!

 

[Mark L]

Quick update: I have a couple of items going on, the goal over this winter is to remove some more weight and build the new short block. I looked over the car for opportunities and I'm going to fab up a tubular K-member and lower control

I purchased a bead roller and sheet metal box brake and was looking for a project to use them. I looked in the rear of the car and thought I could save a good amount of weight.

Well it turned out to be a touch over 45 lbs when it was all weighed out.

Starting:

I attached a cross bar between my strut towers, you can see where the old down bars interfaced the floor previously.

 

[Mark L]

Some of the stuff cut out:

Fabricated tube structure:

New equipment sheetmetal box brake & bead roller:

And the final product, looks way way better:

Absolutely amazing craftsmanship not only for the rear floor but for this entire build. Extremely inspiring, if I owned a 1g this would most definitely be my go to thread when improving my car. I hope you can make it into the 7's!!! That was a big jump from 9.1 to 8.86, the way you have made your car I can definitely see it happening.

 

[JohnTSI]

Mark, what did it weigh when it went 8.8?

 

[Mark L]

It was 2575 with me in it.

 

[JohnTSI]

WOW, mine was 2820 before and now is still 2695 with me in it. Is your still all glass?

 

[Chumpaumpalumpa]

DAT SAVE!!

 

[Mark L]

The windshield and doors are glass. The rear hatch and rear sides are the flex a lite lexan/polycarbonate kit. It should be a hundred pounds lighter for this season and make more power.

Are you ever going to switch to RWD?
