Great passes for the first time out! Shes hauling the mail for sure. Nice to see people actually building AND testing their cars. Bumper Shutters look good too

Nice runs!

What was boost on those runs?

What's target boost?

i hope mine is that calm going down the drag strip. that car stayed nice and straight and very controlled for that performance.

I'm pretty sure the shutters are doing their job at this mph. I love the way they look!

Very stable car. We are using the D2 suspension. Keep in mind that we ran this time on hoosier cheater slicks(drag radial)....looks like everyone else that's running these times is actually running a full 26" slick. Anybody have an idea on what mph difference a 26" slick would have?

Ya good point on the aero helping a lot. I have no idea how much difference the different tire would make. I am guessing it will hook better and pick up more mph so lower ET and more mph.

What boost were those runs at?

50 psi in 4th gear.

I should have specified. What boost were you seeing on the 2 quarter mile runs?

He really meant 50 psi in 4th, as 39 in 2nd, 46-47 in 3rd, 50 in 4th respectively.

I'm not trying to pick a fight, so I hope my comments won't be taken as such. I really like the car and you guys have done a nice job with it.

But, I am just trying to understand why this car only trapped 158mph in the 1/4 mile while blowing 50psi through it with a GT42 turbo? This is a huge turbo. At that boost pressure that thing should be moving a ton of air, and it seems to me that this thing should have been trapping 165+mph. Honestly, I wouldn't have been surprised with close to 170mph.
Consider how many cars with t3 based 6766s, 6466, 3794s, etc.... are going similar trap speeds these days. Heck, there are some cars with 6266 and HTA3586s that go mid-150s all day long.

Curious about the weight of this car? Is it more or less a full-weight street car?

the logs of boost curve makes it pretty clear why its not as fast as the 1000whp suggests. spends half the time in boost recovery going down the track.

Thanks. I missed the weight.

I breezed over the log, but you are correct about boost recovery. This shouldn't be the case with the dogbox transmission, but I'm sure he's still getting used to driving the car. With that trans you don't even have to take your foot off the gas pedal as long as you've tuned in a anti-lag at your shift point. This would improve between gear boost loss dramatically on this car.

Is this a billet-wheeled GT42R or is it still an old-school cast wheel turbo? Is it a 4294 (71mm compressor) or a 4202 (74mm compressor)?

crx-si

This is a 72 mm billet comp wheel, not the 4202. He lifted between the gears if you look at the log. The car weighed in roughly around 3000lbs with him in it. Also if you look at the dyno graph, it made 1000whp at 55 psi in 3rd gear. On the log, 3rd gear hit 46 psi so definitely not at 1000whp. I can give it much more if need be. This is Mario 2nd track outing so I think he did very well. Thank you for your inputs.
