it was a beautiful day on sat 3/20/2021
i got 3-runs in finally at the drags in 1-hour
temp was 72-75* and the DA @ the Track was 7329 and physical elevation is 5295
over 1-mile high.
this is first time for this combo and first run down the track in over 6years.
running thru full exhaust and 2.5'' flowmasters dumping at rear bumper
left the T400 in drive to shift on its own.
no burn out on first run, small quick burn out on 2nd and 3rd.
first run seemed to spin to the 1/8mile
second not as bad
third it launched better but had to pedal it to hook it killed a couple of mph.
so i didn't do anything special to the car, drove it 20miles to the strip and then back home.

Lucky you and not bad #s at all for early in the year

I will not be getting my car out until April and then she is off to the Trany Shop for some Warranty Work
since I think the New Converter took a crap on me and or the Trany needs some Fine Tuning

Mid 120s in the 1/4, you have easy high 10s with some traction/60 ft improvements

My 4000+lb 10.70s street car at about the same DA goes through the traps at 126-127 One of these days I'll bring it down on a work trip and make a run at ABQ Dragway or at least bring my daily and see what it would do (slow).

Impossible. According to conventional internet wisdom, you cannot run time like that with "blowmasters" (sarcasm)
Nice work. Whats the rest of your combo?

i had hoped for more but i'm at a mile high in elevation, that kills HP even with a blower

Your car rips through the back half like the track is downhill lol.
126 mph with that air, she's a ripper.

That's pretty good, it's good for 10.80'[email protected] at a sea level track.

Nice job! I know you don't want to hear this but I went from a 50 series flowmaster to magnaflow and gained a couple tenths on a naturally aspirated 5.3L V8 in the 1/8. Just felt like the top end was freed.

Engine masters just did an episode about mandrel vs crimp bent exhaust, they used a magnaflow knock off vs a dynomax super turbo and were astonished that they lost 0 power from the super turbo.
