Its so nice seeing it on the road and hearing it burn rubber. Well done!
Thanks.... That is a controlled burn.. LOL If I just lay on it from the start, it tear the tires up.. I am experimenting with clutching and camera placement right now, and just thought a few guys would like to see the preliminary stuff..
Here is a better video of the front suspension working on one of our pretty rough Oklahoma roads, and it all feels great.. In this video, you will hear some dragging noises, but that is the oem mud flaps dragging the ground, so I will have to trim them just a bit.
At about 3:30 on this video is where the rougher road kicks in after I accelerate to about 80mph.. I should not say this, but I missed 3rd gear and went into 5th instead with the short throw shifter, so I went from a 75mph 2nd gear to 5th gear.. That being said, you can also tell how hard the car actually bites without slipping to get there while not at full throttle yet, so I think the 1/4 mile time will be manageable..
I did a quick edit on the GoPro video's with the GoPro editor program, so here it is. I will have some 1/4 mile track video, along with the 2.5 mile road course video's coming soon, bu I wanted to practice up a bit.. LOL
What is the Transformer like car in the last pick because i've been looking for an oddball project.
That is a 1982 Bremen Sebring, and it is currently on Ebay so I don't have to store it over the winter.. Here is a link below, and it should answer most of you questions about what the hell it is.. LOL

Here are some details on the Gearing of this car, and I am taking to a Test and Tune day at a local drag strip to get some 1/4 mile comparison times, so does anyone have any guess on what the outcome will be? I am running it on Street Tires (B.F. Goodrich G-Force 265/35/18's), and they seem to grip very well, but I will not have no where near the grip a set of slicks would have. I am wanting a comparison to the modern production cars so people can get a better idea of what the numbers mean, so I wanted to keep street tires instead of slicks for that reason.
I have some local drag guys that say that I will be lucky to break a 12.5 sec 1/4 mile, and that is due to the Power/Weight Ratio, Standard Transmission Option (Clutching Skills), and tire option and width, but a few of them said it would more than likely be at a higher top speed than the typical 12.5 sec time, because I will be able to make up some ground for top speed after the grip kicks in. This all speculation for sure, and I wonder if anyone might have some guesses as to what they think the time and speed will be.. I will say that I have honestly never been on a 1/4 mile track, so that will have a definite factor in the time, so you might take that into consideration.. I have done all the typical street hot rodding over the years, but I am sure there are some definite differences..
Less than 2600lbs
Engine RPM 6800
Axle Ratio 3.50
Tire Height 25.3in
Man if you can crack a 13 for your first outing in this then id be happy with that aye. Your probably pulling 4th gear at some point aswell. So Ill guess 130mph? Im keen to see how you go.

Looks like you were spot on.. LOL
I took the car to the drag strip over the weekend, and I am very disappointed in the performance of the tires on the track. I am running a B.F. Goodrich G-force performance tire, and I thought it would be one of the better street tires to run due to being used on a lot of autocross cars, but not in this case at all.. LOL Track conditions were not the best either, so I had to start the car off in 2nd gear and slip the clutch while trying maintain traction, and I basically broke the tires loose all the way down the track to about the last 75 yards of the 1/4 mile. I was running a horrible 60ft time and 1/8 mile, but some how still did 110mph at a horrible 13.7sec in the 1/4 consistently at this track. Even though it was like driving on ice the whole way, the car stayed straight and stable the whole time, and there wasn't any wrangling the car to go straight at all. I will say the McCloud Clutch held up very well, and I got that clutch so hot that it actually had heated up the Dot4 fluid enough to expand and tighten up my clutch pedal to where I had absolutely now slack at the top.. LOL
I took the car to another track/show the next day, and the track was in a much better condition, but they only run an 1/8 mile there. The tires still didn't work there, so I still had to continue starting in 2nd gear and slipping the clutch, and was running a consistent 8.3 sec at 90-92 mph. These tires work great on real pavement, and I was a bit surprised with the performance on the drag strip, but I absolutely didn't have any of the launch I am getting on the public streets.
Here is a video below, and I hope it demonstrates some of what I am talking about with the wheel spin and driving on ice, and you can really see that in the 2nd frame of the 1st video before staging, because the two times I tapped the throttle with No Brake, the tires broke loose and I hit the rev limiter instantly.. Before anyone starts talking about too much horsepower is the issue here, I can honestly tell you that isn't the case on the regular streets, so I will have to do a bit more tire research for drag racing. I was really not wanting to get a set of performance slicks, because I wanted to do all my testing and setup with street tires for comparison reasons, but I suppose new car manufactures have perfect street conditions and private tracks.. I will say that the 2nd day on a better track, I was kicking the hell out of the new V8 Camaro's/Mustangs on a level playing field, because they were breaking loose as bad as my car was.. LOL
I do apologize for the video, because it seems the person I let have the camera didn't know the best way to do it.. LOL I did about 12 runs that night, and this was all I was able to salvage out of the footage.. This was just an initial trial, and the better coverage will be done during the day for better quality
This is the car taking off on the public highway, and you can see that I don't have the slipping problem I had on the strip, and all I had to do here is manage the throttle to get better results.
Here are a few video's of Volvo X on a 2.5 mile road course, and I will have to work on the camera positions just a bit more the next time.. For the first initial run on Daily Driver capable settings the car did absolutely great, and with a bit more camber and a sway bar that is about 30 percent larger in diameter than the IPD bar I have on there now, the car should do much better.
The preliminary idea for setup on the next session is to stiffen the front spring setting just a hair and see about getting more of a performance sway bar than is offered for these cars, along with a more performance/track alignment. Keep in mind that I have this car setup for daily driver also, and the car was driven over an hour each way to get to the track and back, so this is more of a neutral setting at this time. We can still play with the coil over Dampening and Rebound settings a bit more on the next session, but I wanted to get some hard runs for our base setting, and then see what we can do to adjust it to a more track friendly setting later.
For the people that wondered about my intake system using the cowl vent was going to have a negative air pressure issue at high speeds, I think the wiper arms tell the tale.. I guess the wipers for these cars were not made for this type of activity.. LOL

LOL! Yea Drag racing is a bit eh. Even my car with all of 100kw was nothing untill i pulled 3rd. axle tramp will also cause them to slip alot. More practice and tuning will iron that out a bit if that was your main focus. Even just seat time would help :P
