Can a stock boost, bolt-on MS3 run 12s with drag radials?

[FMOS Racing]

I was actually a beta tester for the original G-Tech Pro back in '92 or '93. That's been a while!

60's on the two better passes were a 1.85 and I think a 1.90. I wasn't even launching really hard since they were just two of my first three hot-lap passes. I really didn't expect the car to go that fast right off the street. I was just trying to get a feel for the tires.

Here's the best two timeslips:

About the tires/wheels, I nabbed this from the quarter mile thread:

The tires were some seriously worn out BFG DRs, 255/60-16, mounted on 2nd Gen Probe GT wheels. A friend of mine ran them for a couple of years on his 300ZX (11.13@135 car on good gas). He just switched to some real fats and skinnies for the car (went 11.10@126 on pump gas Wednesday night, improved from a 1.73 best 60' to a 1.48 best 60') so I borrowed his old ones.

I really wouldn't recommend that tire for a couple of reasons. First, the BFG compound is old. Nitto, Mickey Thompson and Hoosier all make much better constructed and compounded tires now. Second, they're just too wide. They throw crap all down the side of the car when you do a burnout. If you turn onto the return road too fast, they'll rub pretty hard, too. Not sure on what, but the noise isn't pleasant...

These are what I intend to run on mine come spring, on a set of Rota Flights - http://store.summitracing.com/partd...317726+4294793322+4294905041+115&autoview=sku. They're a much better tire in terms of tread and they're about an inch and a half shorter than the BFGs I ran, so I'll gain some gearing, too. Since I already have to shift into fifth, I might as well get all the torque mulitplication I can.

The term "driver mod" is kinda common around the dragstrip. When I botch a run, I'll typically joke that I, "lost the driver mod." The pass in the video is actually one almost totally devoid of "driver mod." It's just the only one I had recorded.

I don't think there's anything magic about running these times, just experience. Matter of fact, after I do it, I'm going to move the tires/wheels over to Dan Murney's car (the Cosmic car in the Injen CAI video) and let him do it in his just to prove my car isn't some "freak."

UHATEIT - If you're still into 300ZXs, check this out - http://fmosracing.com/videos/james300zx.wmv (that's on pump gas). I've been preaching tires and coaching his launch for a couple of years so I'm pretty proud of how well that car is getting down the track. Should go very low 10s on good gas.

proper staging would be worth a tenth too, I bet! he staged hella deep!

I said Rota Flights, by the way, and that's wrong, it's the Slipstream. Flights only come in a 15x6.5", not nearly enough wheel for that tire.

I wana get some nice 17 or 18's and run drag radials daily from march or april til october, not a bad idea lol

 

[FMOS Racing]

The answer to the original question is,"Yes." 12.91@105 backed up with a 12.94@106. I'll get videos up as soon as I get a chance to digitize them - and this was at IRP, which is not known for being a very "fast" track.

The car has a 12.8x in it if I can get it all together on a pass.

Now it's time for 18 psi.

I know several guys running 12.7-12.9 with basic bolt-ons and slicks. The MS3 isn't bad considering that FMOS is running a high 12 with just 3 fairly cheap and basic mods with no tuning. We need someone running a 12.4-12.6 to show the Suby guys that our car has what it takes

Time to get an upgraded TMIC FMOS, it will get you to about 18 psi and you will notice a difference.

 

[sleeper3]

12.9! nice! congrats!

I know I have a 13.2 in my car as it stands. I'm hoping to be in the 12s with basic bolt ons and radials. I think it's very possible!

Don't flame me guys for posting a couple GTech Pro charts! I, too, know this is not the same and not as reliable as strip time slips.

I'll be taking my little silver MS3 to the strip in a week or so, weather permitting. But I was curious as to what my current mods showed, so I made a couple runs recently.

My past experiece with the GTech Pro is that on several cars I have tested at the strip this accelerometer is the most accurate of the bunch out there and has been consistently plus or minus one tenth of a second from the strip data.

The only significant variation has been trap speed. The GTech Pro calculates absolute speed at the end of the quarter while the strip timers average the speed between two beams, the first being 60 feet before the end of the quarter and the second being at exactly 1/4 mile.

This means the GTech Pro will read trap speed optimistic by about 1 mph.

GTech Pro accelerometer is an excellent device for practice and to see if mods improve performance, but is not to be taken literally.

Just for fun, what do you guys think about these two "mid-13" runs on street tires? The hold back is still the crappy 60 ft. times and having to feather the throttle in first and second to hook up. I have other print-outs showing the g-forces on each run that really show the adverse effect of tire spin and trying to hook up on launch.

Congrats to FMOS for the real 12.9's.

I don't see any problem with those numbers for what you've got done to the car.

if someone can find driver311 video of him beating a viper I'd love to see that!

But if he had an MBC he wouldnt be running stock boost then I guess.

for the OP, great video!

didnt beat the viper but damn, mid 12's

Wow! Some great driving.

Thanks for the very good vids and the excellent driving.

NICE!

these cars are pretty sick. 12s with minimal mods!

 

[spoolin_05]

Very nice what slicks were you running in that vid

 

[FMOS Racing]

They're Hoosier drag radials. 225/50-16s.

After watching the vids I realized I need someone who understands FWD burnouts to line me up in the waterbox. The guys at the track pull me too far forward and the back tires end up in the water. They slide instead of holding the car still so that I can get some heat in the front tires.

Only the first burnout is worth anything at all. And, of course, that was my best 60' of the evening.

Oh i thought you hadnt put the hoosiers on before that race...im looking at doing the same set up. Did you put them on the rota slipstreams? If possible links to the rims and tires you have on your setup would be greatly appreciated. Thanks.

I picked up a set of FD RX7 wheels for really cheap here locally. At just over 13 lbs each, they're a great drag wheel. Another great choice is the early 2nd generation Probe GT wheels. They're fairly light, too. You don't want the chrome "swirly" wheels that came on the later cars because they're significantly heavier.

These are the tires - careful shopping can find them cheaper. They also make a 255/50-16 that would be a better choice in a higher horsepower car.

[spoolin_05]

Do you think the 255/50/16 would fit on the ms3

 

[Speedkid]

Nice times dude.

 

[FMOS Racing]

I am way, way late on this (been traveling for work since July), but I ran the 255/50-16 BFGs on my car in the early videos. They rub at around maximum turn, but they're fine for using at the track if you don't turn too tightly (that's on the Probe GT wheels, obviously wheel offset will impact this).

Now I have to tell you that the 255s throw a lot of crap down the side of the car when you do a burnout. The 225s don't.
