I am going to be getting some Bogarts soon and need to find rubber for them. I have a H/C car, Moser 12 bolt w/4.11's. I will be spraying probably a 100-150 shot on it. I really don't want to shift into 5th. I want to be going through the traps in the top of 4th between 6300-6600. If I will be shifting at 6500 rpm...what tire would keep me in 4th?

I would like to have the option of driving on the street with these tires...cuz I sometimes go out to the track by myself and have no place to put my 10 spokes. What tire could I run...with limited street use...that would still get me the traction and 60ft. times that I want? I will be launching pretty hard....I am not going to be rolling into it.

Also..what do you guys like for rubber up front?

I have been searching a lot...and found good stuff.......but I am getting mixed signals between QTP's and ET streets. Are they going to hook or not? And some people have not problems on the street, and others say that it is a death trap...what is the deal?

26x11.5x15.... QTP's if you don't drive on the street much and ET Streets if you do drive on the street a bit. ET Streets are stiffer so you don't wear em down or tear em apart on the street but require a larger burnout to get em to hook

if you are spraying a 100 -150 shot, you will definately run out of gear in 4th with a 26 inch tire with 4.10's. If you don't mind hacking up the car a bit, go to a 28 inch tire.... or swap in some 3.73's and stick with a 26 inch tire... all depends what you are willing to do to the car. A 26 inch tire should still hook ,and e.t streets aren't bad to drive around on, but watch out if it rains... wet roads are a definate problem with them. You could try the e.t radial, not sure how they are in the rain yet, but then the e.t street's I have are done, I'm gonna give them a try.

whats the revlimiter set at? at 127 (good for a mid 10) you'll be at around 6700rpm. 3.73's would fall flat on there face off the line... darn 2.66 first gears

www.intercotire.com i use the 26x11.5x16 m&h racemaster cheeter slick w/4.11's/m6. i pulled a best of 1.57 60 foot and the m&h tires has out hook m/t's on my back to back test runs. hoosier is a great tire too.

yeah you'll be shifting into fifth regardless of your setup unless your limiter is at 7000. You'll probably still be bouncing off it a little if you trap over 125 which you have the ability to. I would just spray off the line on 26's and shift into fifth. That's the best option i see.

okay, since you want to go thru the traps at that low a RPM, maybe a 28 inch tall tire is for you

with 4.10's and and 26" et streets i managed to go 135 MPH on a small dry shot..but i was not spraying out of the hole nor was I using a WOT switch so spray wasn't on full time..but even then i BARELY made it..i crossed at like 7000-7100 rpm in 4th.

if you are going to shoot that thing out of the gate and launch farily hard and want to clear the traps run a 28" tire with that gear.

N/A it'll be too much tire for that gear, but would be perfect on the gun.

I think you may be ok with the 4.11's:

http://www.f-body.org/gears/

According to my calculations, I am good to 127 mph because my rev limiter is set at 6800rpm. I plan on a 100 shot next Fall, and think I will be crossing the traps ~125 mph.

If I am wrong pls. correct me. I will be running 245/50 16's...

Edit: Sorry that table doesn't always work

when your tire is at 18 psi or 16 psi it isn't a true 245 anymore. Itchygomey98 runs a 28" tire m6 with 4.11's. He crosses the traps at 125 to 127mph bouncing off the limiter pretty hard. I would think that anything over 125 you would be better off hitting 5th to cross the traps at 6300. Most of the time you want to gear your car to be at the top of the powerband as you cross the traps. So you would want your peak hp at 6300 and your limiter set at 6700. a 26" tire will not be enough at this rpm.

What if I sack up....actually grow some nuts....and shift past 6500. I am just worried about the wear and tear on the motor...should I be?

Does Hoosier make a 27" QTP that is a made for a 15" rim...or is that for a 16"?

Also...I will not always be making nitrous passes.
What would be the best for both worlds? Anything? What would I have to shift at and rev to in 4th to stay in 4th...if I went with 26"?

they make a 27 inch rim and a lil more RPM wouldn't hurt. just as long as its not 7200 on the gun

mike#9

iTrader: (3)

What do you think I would have to shift at then to be ok on a 26" or that Hoosier 27" tire?

Here is a good calculator to help you figure out what would be your ideal tires size for your set-up.

http://www.race-cars.net/calculators...alculator.html

A heads/cam car with a 150 shot could probably run in the 130mph (bottom 10's) range in the 1/4 mile

At 130mph maximum, 4.11 rear end and 1:1 in 4th gear here is your approximate rpm for tire size....

28" = 6420rpm
27" = 6655rpm
26" = 6910rpm

At a more conservative 128mph with the same set up.....

28" = 6320rpm
27" = 6550rpm
26" = 6800rpm

I would deffinately go with a true slick rather than the ET Street. I fought with the 26" ET Streets all last year. I went with the 28X10 Goodyear Dragway Special tire. They fit with very little modification to the tire well (just had to trim the back plastic about a half inch). The Mickey Thompson 28X9 ET Drag will fit without any modification at all.

there really is not best of both worlds.

anytime you are spraying an M6 car you are going to either have to use two diff size tires for n/a vs spray or pick which is more important to you and sacrfice on one. In your case it sounds like you are going to have to use the bigger tire so you can spray at all(clear the traps) and sacrifice some n/a.

GueSS Who

I can tell you this. I did tha same thing. I had a 100shot on mine though.
I used 26/10.5/16 ET Street with 410 gears. I had to shift into 5th gear and I trapped 129mph

Do you guys think that a 27" Hoosier QTP would work?

How shitty would a 28" tire be N/A? And how much work does the car need (beaten I mean) to make a 28" tire fit?

1madss

iTrader: (10)

With 4.11s the best tire would be the 28x9 slick. I run a 26" slick witha 6600 rpm rev-limiter setting and I hit the limiter shortly before the traps. Most of the 6 speed H/C racers run the 28x9.

I am told by Steve from SJM that his rims need a minimum of a 11.5" tire....so how can I run a 28x9? The rim itself is 9.75" wide?

bad2000ss

Recommended minimum rim size for the M/T 28X9 is 8".
