Low trap speed?

[RED09GT]

Near stock my car picked up 23-25 mph on the big end, 79-81 in the 1/8 mile and 102-105 ish and was about the same with bolt ons and 4.10's it would be 82-84 1/8 and 106-108 in the 1/4 with yours only picking up 19 with way more hp than mine had, I would be looking for clutch slip or doing some datalogging to see if there is something up with the tune.
I wouldn't spend a dime on control arms, 1 piece driveshafts, or anything like that until you figure out what is currently holding the car back on the second half of the track. There is lots of improvement that can be made on the front half of the track with more seat time, cutting good 60' times isn't as easy as the internet would have you believe-especially with drag radials and a stick.

Agreed. I have achieved great 60' foot times on street tires, which mean they're possible for everyone BUT out of maybe 75-100 runs, I nailed my best 60' foot times 6 or 7 times. Most people giving 60 advice have never gotten a sub 1.9 60' in their own car lol

Agreed with this 100%. In this case the missing MPH in the OP's trap seems to be lost on the big end, not in the first 60 ft.

I'm going to guess the clutch is slipping.

You guys are picking up pretty good on the top end. I'm seeing 19-21 mph gain myself.

There's a ton of other things you should take care of first before throwing more power at the car. 1-piece driveshaft, lower control arms, adjustable upper control arm(since you will need to adjust the pinion angle), lower control arm relocation brackets are a must since you are lowered, and the list goes on.

Work with what you've got now and don't waste money on a dyno tune for a bolt-on car. I've made over 600rwhp through an automatic and haven't been dyno tuned.

buy a set of 17" OEM wheels from craigslist and slap on a set of Mickey Thompson ET Street bias ply tires (p/n 3743 26X11.50-17LT) - they work well with manual trans, and are DOT approved so you can run them on the street if you want.

get a set of lower control arms, and adjustable upper control arm, and relocation brackets (since you're lowered). Set the pinion angle to -2.5 deg.

keep the stock 2-pc drive shaft and launch at 5000+ rpm (you'll need front/rear drive shaft safety loops in place). If it breaks, get a take-off cheap from someone that put an expensive 1-pc in their car.

for reference, my first 1/4 pass info here

there's more to be had from my car, as I experiment with launch rpm, tire pressure and strut/shock settings. Once I get my suspension dialed-in, then I'll consider adding power...
