Superlite Coupe at Texas Mile March 2023

Brought the SLC down to the Texas Mile in March 2023 after a miserable fail in October 2022 when my front splitter brackets broke. Won my class (naturally aspirated, manual trans, RWD) with 187.3 MPH

I hope business works out and i can build mine. K48 v8 graziano or better transaxle set up for paddleshift sequential operation for speed of shifting. Few other weight reduction bits. Tracition control. Biggest tires and brakes i can fit. Lightest rims. Probably some aftermarket carbon rims for corvettes. But also a full tilt nice interior and lots of heat shielding and sound deadening. Boost set up few tricks along with a few motor build tricks for a track mode and atreet mode. But gonna have it dialed. K48 should work for the Graziano well but still gonna regear it for theoretical top speed above the ford gt. And set up for the rpm range.

[@yogamon]

It’s been 7 months did business work out and you built it?

[@bmxriderforlife1234]

@yogamon lol business works slower then 7 months. But lol investor talks. Take like probably 24 to 36 months once I get capital for shit. Then I'll actually have time to do shit. Formal business proposals are a frigging pain in the ass to write. And gotta deal with actual legal stuff and lawyers. Especially on something that's going to be international, and dealing with production facilities.

Only thing I really miss about living there is the Texas mile in ingleside area near corpus and the fishing is amazing best Gulf of Mexico fishing in the country you can catch massive speckled trout and other fish off a pier or bank and no boat needed like here in Alabama

[@nickdelorm86]

Whats your gauge/display setup? Very clean!

[@markb5066]

Thanks! It's an AIM MXP Strada display

[@superrookie1554]

Nice car. Sound really suits it. What contributes the most to that higher pitch?

[@markb5066]

Thanks! The high pitch is probably just because I shift around 8100 rpm.

[@youknoweverything7643]

He is talking about that high pitch whining and it's the gearbox he is probably using all straight cut gears like we use in circle track asphalt latemodels and stuff that's where you get that nice high pitch beautiful whine from and he is also turning 81000 rpms. I'm my asphalt circle track open wheel modified at certain half mile ovals if there is a wall all the way around inside and outside of the track it will make my ears feel like they are gonna burst and are bleeding from the high pitch of the motor being turned to 9200 rpms and the transmission gearbox whining. I run a 896 rear wheel horsepower 400sbc in my asphalt modified it's a old NASCAR cup series engine that I got off a old NASCAR truck series driver that use to own the race track I race at locally and I had it rebuilt and the engine guy built to where it can safely turn 9200 for 100 laps plus no problems all season long with out worrying about blowing up and hear it is same motor has 120 races on it and still running up front. But what y'all do is very crazy motor wise

[@bmxriderforlife1234]

​@@youknoweverything7643my ls in my gto is very similar to your truck motor. Was set up to go 10k now does 9500. Things a frigging ridiculous monster way less hp now but alot more endurance to it. It got me more into high revving builds which is influenced my dream slc build. K48 Honda based v8. Flatplane crank. Should have the power and torque of a domestic style v8 and still Rev out like a European super car. Play with the gearing and tuning and it should have the reliability to match the gm based builds with a high revving nature and speeds to match the best. And a better trans reliability since its in a much lighter platform. And I'm gonna do the sequential mod and paddleshift with electronic assistance. In vein of the old repurposed f1 style single clutch paddleshifts but more reliability. Mated up gearing wise to an engine that fits the transmission well with further tuning to pair them. And no adapter plates. And get some extra room in the engine bay. If I can manage to get it tuned na the way I want. Boost system. Series twin charging super and turbo. With a way to bypass the super and fully open bo valve street mode. Full boost track mode. Repurposed 911 exhaust electronic controlled choke valve. And a dump valve. So it can fully bypass and open for a straight pipe track mode or quieter track mode. Keep it low as possible in weight. But also have that high hp mode for God tier levels of power to weight but a reasonable driving mode as well. Reliability like a ls but performance like the best. Along with the best traction control and tires and brakes possible.

[@rick3446]

What engine you running? Sounds great 👍

[@markb5066]

Thanks! It's a short stroke LS7 with solid roller cam. 574RWHP.

[@dgo9121]

What power is your LS7 putting down to the grown?

[@markb5066]

570 RWHP, 440 RWTQ

[@christophertibbetts2458]

Why don’t you down shift and engine brake to assist your actual brakes?

[@markb5066]

They have about 1/2 mile of space to slow down so plenty of room. I was also using the opportunity to tune my brake balance.

[@brianpope8280]

How much real down force @150 mph, 180 mph, 200mph. Or somehow you tested it at any mph? 187mph at a mile with 2400lbs and 570 whp destroked LS7 is real slow. I think of downforce caused it. Stock c7 z06 on stage 1 wing went 180-185 mph at mile. 1200lbs heavier.

[@markb5066]

Sorry no downforce testing. It was squatting quite a bit at speed but I have no way of measuring it. I agree the car should be capable of more (aero, alignment, etc). I even noticed when I got home that my #7 spark plug was melted so that certainly didn't help.

[@brianpope8280]

@@markb5066 Ouch. I hope it go into 190's mph range.

[@NationFirstGreenville22]

What engine do you have again? Your rpms were going above 8k

[@markb5066]

It's a solid-roller, de-stroked LS7
