With the way your turbo should come on, I'd say it will either spin, or 60' hard. I was looking at my logs from last year, and realized my 1.49 60' was a 5 lb launch, and my boost controller ramped to 18 psi in 2.2 seconds. Had a 5 psi/sec limit that I had overlooked. With a manual boost controller, there is no ramp in other than the speed at which the turbo spins up. That might be why yours is spinning as well, with no limit on ramp rate I can do 15 psi in less than a second from cruising vacuum, that will hit the tires hard from a stop. If you hook it up, the car is going to fly.

Guys like FieroX, Don Kraus, etc that have run 1.4 and 1.5 60' times have seen the same issues I have. I've got no issue with people taking it easy out of the hole to save parts, but I don't see anyone else talking about their lack of failures when someone else has issues. It's just trolling, and I guess i should expect it from him.


Fierox broke axles because they were just designed wrong, don broke going into 2nd gear.

I leave a little on the table in the first 30 feet at the track because i know my trans is on borrowed time.. But everywhere else I go as hard as I can go. First gear still never fails to suck the blood from my brain and blur my vision good, so i think you are quite off base when you say I am taking it "super easy".

I also ran a BONE STOCK 65e for years without issues and hard launches.

But you didn't say (this time) that you had it shifting so softly the BOV would sneeze a bit.

Yeah, it was really sweet. Worked damn well and you couldnt complain at the .1 seconds lost to some extreme torque management settings.

Update, The stuck -9.3 LTFT was solved by starting over with a new base tune.
I know BV and a lot of other guys on the internet had the same issue.
I'm not sure what causes the issue but I will search for the root cause.
I also re-gapped the AL 103 spark plugs to .060 but that didn't seem to make any difference on turbo "hit".
The thing did "hit" hard on stock plugs so if it isn't the gap it may be the heat range???
Hell, the hidden power maybe unleashed with the tuning as the new base tune hasn't been optimized for performance yet.
If I don't get the "hit" back then I will test with some stock plugs and then on to the ALS as I need her to light them up off the line.

What boost controller are you using, and what turbo? I think I read Precision 6262 and a .63a/r hot side but was that a T3 turbine housing or T4?

and Nosrac is running a 6266 with a .81 T4 hot side?

I did a little more testing and tuning and can finally enjoy a ride around town.

One thing I noticed is that my exhaust velocity was significantly greater at idle when I could burn rubber off the line. What would increases the exhaust velocity at idle( lean condition)?

Currently it purrs @ 800 rpm at idle and the exhaust velocity and sound is tame as compared to before.

I like the tame sound but need to figure out why I can't burn rubber on launch anymore.

I am still trying to get back to that speed hitz....LOL

I know the car has it in her as I felt it before and see Formula's car do it on the regular. I'm just not sure what the issue is..yet

I suggest you stop saying "hits".. It is completely non descriptive and pointless information.

Give some real data, psi/afr, logs, spool rpm, observed lag, timing, etc. Also suggest going open loop unless you really know what you are doing with that setup.

Ulysse speedometer in HUD mode (non reversed) it has a lot of great features for a free app, highly configurable if you spend a few mins with it.

If it really can hold over 400whp reliably then yes.
