Where the hell is the intake ?

V12Godspeed

I think that may be a secret of SpeedDriven and Soulsearcher. It definitely is innovative and applaud Marcin's creativeness. Guy knows how to do things.

I've gotten a ton of pm's about the 1/4. While appreciate the skill that goes into honing the take off, its just not my thing and never has been. I'm a track (Road track) and top speed junkie. Keep in mind that had I been able to install the 15 inch Rotoras on the back, I would never have been able to put anything less than a 20....so bye bye drag tires.
However because of the low offset on my current wheels, I was not able to fit the upgraded rear brakes. I have no plans to use spacers to push the wheel outside the fender edge.

I may later in the summer make a trip to the drag strip.

Additionally most of you drag pros should easily be able to project what this car will do with a tight launch. You have all the data you need. The car ran 120 with about 650hp (give or take) @ 11.9 with a bad driver (me). Marco ran 10.7x/low 130s with 850hp. I figure with 1100+hp it will be about 141 and if the launch sticks, then maybe 9.9


The car is getting "more"....stay tuned.

I agree your guesstimate sounds very likely, now you CAN get us plebeians a SOUND clip can't you I demand to hear that V12 rig now that Marcin has completed a masterpiece

Well I have nothing to do this weekend....what a welcome thing. So might as well be a verbose forum nerd.

Rick u crack me up....plebeians...

I dont even have the car. Its back at the spa, getting "massaged"... again....so much so that the genius behind this evil leviathan keeps counseling me on the vertues of restraint and to take it EZ for now.

The texas mile was but a prelude and not the final story. Working towards something else !!

I will tell you that my big concern was the car sounding like a redneck (I'm cool with rednecks...my wife is part redneck) in a '79 nova with rust holes in the muffler (we all remember those high school days) however that is not the case. Very subdued at cruising but when u squeeze it.....well...in the words of one my office managers..."sweet baby jesus" (no pun intended). First time i heard marcin fire it up, Sat. morning to back it out of the trailer....my comment was..."yeaaaah baby"...as cheesy as that sounds.

Love it! How's the BOV sounds I think you should change your handle to "Evil Leviathan" it's much more suiting...

We'll get a sound clip when its on the dyno some time next week.

I received a few PMs about how quick this project moved but the truth of the matter is this project did not start in November 09 but March 09 (Long story). So this car has been gone for about a year.

Looks like I should be getting it back soon. Texas was just part of "tuning" the car.

Still working on getting those vids up. Plus the guy that filmed them had no concept of "short". They are 15-20 megs each, so they have to be edited. This friend has them and he's still out of town.

I finally got the missing parts and got the hi-res 4-camera in-car system running. Looks great on a 4-way split screen. Films at up 120fps! I have not tested the high speed camera suction mounts that go on the outside.

Since I could not find what I was looking for, I had STTsafety make a 5 point SFI/FIA (Now I have 5 years rather then 2...for those who know what I'm talking about) harness with snap-in hooks so I can take it out when not needed. I certainly was not going to drive an SL around with a race harness. The eye bolts are being installed so as to be inconspicuous. In July I will start the process for getting the "integrated" roll-cage and flip-up OE roll bar approved as a full cage so as to be teched for 190+ in October.

Below is the reason (Pnaumatic pump connector) my trunk, keyless start, keyless entry AND convertible top would not work intermittently and why my consumer batt. would die after a week of sitting



Tires!
I am told by SpeedDriven that my tires will not even start hooking up until past 80mph (I like that problem).
I've had 3 sets of Falken 452s. (Yes I know they are not great). Because my tires last only 4000 miles (sits very low-serious neg.camber & track days-not drag). Flakens are just cheap (305/25+255/30R20--I wont change to 19's).
I researched tire options yesteday since now I have no choice and came up these three;Advans, PS2,Invo. I passed on Sport Maxx for good reason.
Noise, comfort, or wet traction are not of importance. Obviously those tires were picked, in part because of the very low Treadwear-UTQG (Yes---LOW).
I may go up to 315/25R20 (Yes they fit), which will still be within 0.8% of OE O/D.
I realize everyone has an opinion on tires but without compartive tests on the SAME size I am looking at (Yes I am aware of several car mag. tire tests and they do not apply here---long story) the only objective number I can use is the Treadwear UTQG and some unpulished tech data that my friends at Goodyear shared.(My past life was with Goodyear Racing Division).
Michelin Cups are sticky as they get but a set installed will run 3000 bucks and last about 1000 mi on my car. Drag radials on street driving would not be smart, since the sidewall is designed with less support. That wraps up my tire options in my size.

Just put the videos on you tube, it will auto compress it if needed 15-20mb is tiny!

Anything new here ?

Dsmed

Car is going back together right now. Alot of interior has been removed, seats, carpet, side panels, rear panels, etc. Reinforcement brackets/plates have been made for 5pt. harness anchors. We made them comply to the NHRA rule book for seat harness safety requirements. Which meant welding up some reinforecements.

Software changes have also been made, once interior is done of to dyno.

DCMETRO22Z

Thx.

blackbenzz

Wow, how much does it weigh now?

Dsmed

Weight will be slightly heavier than before actually. By about 8-10lbs, we added some 1/4 steel plate. Its all going back in, most of it did yesteday. We just had to get the stuff out of the way to make the necessary bracing for harness anchors. If i had to guess the car is about 100-150lbs heavier than a stock SL600.

soulsearcher

Things are taking a little longer than expected.

The torque limiter has been set to max, which is around 1000 foot pounds but that is not enough with 25/26 boost. The goal is to remove the limiter completely so we dont have to go back 20 boost.

5 point racing harness has been descretly installed to allow for quick removal when on the street.

Dsmed

I hope those new tires do a better job. Took it out today to get some race gas in it. While on the expressway with a wideband and data logger to see whats going on with the part throttle fuel trims with those big injectors. So i'm cruising about 72-73mph, and well open road as far as the eye can see so I...
You guesses it, WOT figued it should just hook and go. But no right around 84-85mph she decides she wants to go drifting Tanner Foust style, Blazing the tires. I'm talking full on burn out of the rev limiter, not I think it spun cause the triangle flashed once or twice.

So when I get the tq limiters to behave like we want them to. 26psi might make Mikey Thompsons mandatory.

OUTCAST

Now that is power in the hands of few!

Sunir

WOW full on rev peg burnout at 85mph! that's just crazy silly intoxicating power!

soulsearcher

Custom made silver 5 point snap-hook, cam-harness.

Removable, seamless and tasteful, thanks to some "creative" engineering.

Yes, I know the sub belt is not the perfect angle but we're not about to install a race seat in an SL. Keep in mind why we did it. (Hint: Ain't by choice !)

OUTCAST

That looks really well laid out I like it.

blackbenzz

Oh man that's awesome! Supra status even lol. Are you going to mass produce the turbo "kit"?

Havoc

Glad to see you didn't install racing seats in your SL. The Custom made silver 5point racing harness looks great. Job well done!

MB_Forever

Very impressive work and attention to detail....
