1/4 mile - Speed limiter :(

[Rob Mugs]

First of all, if it's not a known thing, do NOT brake torque.  Ran several 14.2s and then just stabbed the throttle and pulled 14 flat.  That said, it seems I am hitting the limiter before crossing the line.  Every single pass was 97.50-ish.  Was are those with larger rims (and higher top speeds) getting?

I'd say you are hitting the limiter - I've seen multiple T1 6.2 guys say the same thing. I've been curious to try mine out but all the racing has shut down around here til Spring. I'll try it out then and see what it does.

If your truck has the Duratrac tires from factory they have a speed rating of "Q", which is 99 MPH. Your truck speed limiter will be factory set to the tire speed rating. (which sucks)

Mine runs up to 112mph

I ran a 13.61 at 101.8, and 13.67 at 101.3. Mine was quicker brake torquing it.  Ran 13.76 off idle.   Mine tops out at 110 ish.  I think you’re loosing something off the line.  My 60 ft times were 1.93s. 8.70 1/8 mile times.

BONE stock?  I know these tires probably aren't exactly the best for racing but those numbers a significant

Bone stock except for 5lb per tire heavier than stock Hankook tires.  3/4 tank of gas unfortunately also, may have had a 13.5 in it.  I launched at 1800-2000 rpm. There is a race section somewhere on here and someone else ran an 1/8 mile a tad quicker than me.

Has to be the tires then.  These Duratracs are likely not the most efficient "race" tire

I’m sure they aren’t helping much.

What settings are you using electronics wise in addition to brake torqueing to 1800-2k? Traction control off? 4wd hi? Sport mode? Are you at sea level? Those are very fast times. My local track closed last month. So I have to wait till spring to blast down the 1320. My all terrain tires are rated to 112 so hopefully I don’t hit the limiter.

You and your truck are really quick. I’ll be happy to go 13.99 or quicker. Dam. I’ll be a year older by the time my local 1320 track opens up next spring. Less hair. Slower reaction time. But hopefully fast truck.

Lol, fortunately reaction time doesn’t effect et.  I sat at the light a bit making sure I was at the rpm I wanted to be before taking off. I went into thinking the same thing, just hoping it would get into the 13’s.
