What is the best 1/4 mile time for any STOCK LONG BLOCK (1.8, 2.2, 2.5 - NO opening the motor, NO low comp pistons, NO thick headgaskets, NO head swaps......) turbo/supercharged converted N/A Subaru motor.

I think the AVO kit runs in the low 14's to high 13's on stock longblocks.

So, what you are basically asking is:

What is the best 1/4 mile time with an RS-T that has not had internal work.

Correct?

Yeah, could also be a 1.8 or 2.2 just has to be STOCK High Compression LONG BLOCK.

I know a guy on here is pushing something like 11lbs on is stock longblock RS, but he hasn't taken it to a track. I'm sure his would be up there though.

I just went to the track for the first time a couple nights ago. My best run was 13.5 @ 101.5 W/1.89 60'.
My clutch is definitely not strong enough. It was slipping too much on the launch and between shifts. The stink in my car after a run was horrible.:barf:

I hit the dragstrip last night & I'm pretty dam rusty on driving the OBS-t...

Car is a stock ej222 single port longblock with NO internal mods (like cams), stock ECU, running a TD05 @ only between 8-8.5 psi to avoid breaking down about 80 miles from home as I drove the wagon down to the track & back - about 80 miles each way. It was down about 41 GTHP from what it makes @ 11psi...lol...

I missed shifts on the first 2 runs resulting in a 14.052, & a 14.334 both with 1.8s 60' times... ? nerves, but I think the Sparcos I put in may require some getting used to on drag runs as the curve around my shoulders quite a bit.
SO
I figured I'd be slow & sure with the shifting on my LAST PASS & ran a 13.875 @ 96.96 MPH
Time slip read as follows:
1.849 60'
5.685 330'
8.804 1/8th mile @ 80.80 MPH
11.525 1000'
13.875 1/4 mile @ 96.96 MPH

I've run 8.6s 1/8th miles @ 82mph miles letting off early & coasting down from 84mph @ 10psi of boost ? what that would be on the 1/4 mile - I'm thinking about 13.4's

Has anyone run better than 13.874 1/4 mile on a stock ej222 + boost?

Bringing this back up because your turbo 2.2 map based cars got me thinking about going this route. Did you upgrade the clutch since you were slipping?
