Hey,
Ill be running or drag radials soon for the first time, bfg 255/50/16's, and was wondering if you guys just heat them up, do a full burnout, or just go around the box altogether. ive ran on ET streets, but obviously a full burnout works best for those. What hooks the best with drag radials?
Thanks,
Brandon

 

Back when I was running BFG's I would do a decent burnout with them. The waterbox only worked if it was well done... light water and no deep puddles.

 

Me heating up my Nitto's

consistent 1.7's

 

Damn you automatics , I'd donate a kidney for a 1.9......

 

WIth my buddies TA (threadedtire) check his sig if ya want.
We would do a hard burnout get the tires to around 190* (if ya have temp gun) then take your time staging the car (round 20-35 secs) this allows the tires to heat soak and become good and sticky. Doin this we were pullin 1.44-1.46 60' consistently.
Yes we do have a damn nice susp package but i belive this is a chievable with some carefull setup of even the stock stuff. maybe not low 40's but darn respectable anyway. In a nutshell you need the front end to rise as quickly as posible and the back to sink as far as pos, to get the max amount of weight on the rear tires. I.E. spring jacks and dead struts/ QA1's set all loose up front and 6 cyl springs and soft shocks out back. Anti roll bars work wonders to. have fun and believe in the stock stuff just gotta be creative

 

I recently found my BFG's hook better if I do I nice smokey dry burnout as opposed to going through the waterbox. Best bet is to try both and see what works best for you.

 

I'm on my 5th set of these tires. This is what I do:

Drive around the water box. Back up until the back tires are in the wet area just in front of the actual water box. Don't guess at where you're at backing up. Open your door and look at where your back tires are. Gently spin the tires over to get them wet. Pull forward a few feet and then do a HOT burnout for ~5 seconds around 4,000 rpm (with your M6 you'll want to use 2nd gear). After the 5 seconds, continue the burnout at ~4,000 rpm and let your foot off the brake (or line lock). As you slowly roll forward continuing your burnout you'll feel the engine start to lug down because the tires are starting to bite. Stop your burnout at this point and roll to the line and stage.

You don't want to get the tires too wet. They have a lot more tread than ET Streets. They will pick up water and sling it up in to the wheel wells, which will then drip on your tires when you leave the starting line.

I run 18-22 psi in them depending on track conditions.

 

Thx for all the replies and ideas guys. I think i will start at 22-24 psi and work my way down.

All 3 sets of Nitto Drags I've owned bit best with a 5-8 second SMOKE SHOW. No water BOX, just a damp surface to back onto and roll off of once hot. of course go around the water and figure it out from there. As for Dry bornouts, I think they eat up the tires too much. Almost like there is too much load on them....Does this sound stupid to anyone? It sounds dumb to me but I have my moments

Both sized I ran, 275/40/17 and 315/35/17, had me consistantly in the 1.80-1.85 range on a decent track.

 

Thanks

Adding to the above, I actually drive through the waterbox since I have skinnies.

 

I defintily noticed that. It does chew them up more. It makes sense cause water reduces friction. No water = max friction. I'd rather be more consistent and get a few less runs out of the tires than get more runs on them and be less consistent. JMHO.

Especially when bracket racing.

 

I got 1.7's pretty consistantly with BFG's w/a 6 speed. Since you have 4.10's like I do try this.... Back into the H20 box pull out a couple feet put it in second rev it to about 5500-6000 and drop the clutch. The thing with the 4:10's & first gear is that it doesn't let the tire speed get really fast like second will. You'll notice alot more smoke in a shorter amount of time. Just keep the car slowly rolling Don't stay in the same spot and keep it reved up high. Let me know if that helps.

 

I just caught this and thought I would reply. I just finished installing my first set of BFGs and we have an event to run against the SVT crowd on Nov 8th.

I understood the burnout procedure , but how do I take off from the light with these things?

Do I feather it out like on street tires...

Bring rpms up to 3,000 and dump it...

or 5,800 dump

Thanks
Mike

 

To not abuse the clutch, when you think you have better traction, nothing tests that theory out better than a 3 or 5 grand clutch dump. Suspension/Weight pending, it'll probably hook pretty good. I'd try a 3 grand dump and instant WOT. Then 4 grand attempt.

Slipping the clutch is just brutal when you're looking for 1.7's. Goodluck with the clutch dumping. With 4.10's it should work really nice with no real bogging. Goodluck!
