My main target are the vxr8's
Not the little lightweight coupe's

Im 3rd in that dept at present and only 3mph behind...

But I'll have a go at it all.
That's the fun part.

My main target is goldy

One day you get a good car
And you can do it till then L

p.s. Mine has done 176 with only a 122 sc
now running alot higher spec

Was this 2010? The only speed I can remember for your car was 169 point something, adjusted for the timing errors in 2012.

2010 was the year JamieP's Supra let go, but I can't find a results table.

All the 500+ bhp N/A cars than run done very well.Would love to see what a 600bhp N/A car could do at TR compared to the 600+bhp S/C cars.

171

Yep.

Im not aiming for any specific speed. Just optimising what I have. Im sure there is 2 more mph in the current setup (first time out this year) and perhaps a couple more with a new cam.
So realistically I think its a 175 max for me with all ducks lined up.

Ill leave anything over that to the smaller and lighter monaro/gts guys.

Gareth and Darryl can see what they can do.

First up looked like a great day out.Reading all these posts with intrest looks like first thing to do to a Vxr8 would be raise the speed limiter and then either change diff ratios or gearbox ratios.This being on a supercharged R8 so question where would you start and whats available on diff's or gearboxes out there would it be a shorter sixth gear or taller fifth

I can rev to 7k and have went over it, but it isnt happy up there.
At TOTB due to the gearbox problems....buzzed it to near 8k a few times when selecting the wrong gear LOL.

When you need as much power as possible to overcome drag etc at high speed to go faster, you dont want to be on the downhill slope after peak power and it's falling off..

At present, mine goes better shifting around 6700-7000rpm, depending what gear etc. Lower gears best to shift a bit early as no grip anyway.

Some do push hydraulic cams to 7500 etc, but I think moving to a solid roller will probably give the best and most reliable high rpm use, and really cant see any negatives other than cost.

Ive had several cams over the years, various engine sizes etc too. But for the most part none have been overly willing to go much beyond 7k.
I could push them, but I'd be doing just that, pushing it for the sake of pushing it.

If I had peak power close to 7k along with the ability to shift a little higher and remain on the power better, I reckon I could get damn close to 200mph in 1km.

Actually mate, Id suggest some/most of this is due to intake limitations. The LS series of intakes is designed to place peak torque in the 4400-4800 range. If you want more higher end torque the Fast will add a couple of hundred. But after that you need to look at Carb intakes. Ask Leatherman why he runs one of these
Also BHP = Airflow (& torque x rpm), stock intakes limit airflow. Carb intakes (or custom intakes) will take you well into the 7k range.
But this is moving power higher in the RPM range further away from street use.

I think people are missing plenty of tricks, they are limiting their thinking to OEM engines where all parts designed for specific uses.
There is a world out there outside of OEM constraints. Very few people venture. This is where many answers lie.

Wow thats a truely st result. I cant even remember doing that. Though I knew Id been to the airfield before.
Must have been before the stroker was fitted. Or at least with a crap tune.

Or you can spin to £7k..

I think Gary said the gear swap in his Trans was not too expensive. I think he went to a 0.71 from the 0.84

Makes for very interesting reading

So following this thread even if peak power was at 5000 rpm assuming it was possible to keep the torque curve relatively flat with a slight tail off towards a 7k redline thus still keeping it reasonably street-able. Why would you go to the extent of custom intakes? I'm intrigued because obviously that makes my goal of 200 in a mile more readily achievable but that sounds like a massive negative in terms of daily drivability...

I can 100% see why you'd do this for 1/4 mile setup but I think any decent very fast road setup with the correct gearing (and help from good aero) should be able to hit 200 in a mile.

Its much cheaper to design on paper first. Of course you need to know what you want/need first too.
But lots of DYOR is a good plan.

Lots of ways to increase airflow. Starts at the intake and finishes at the exhaust. No one piece is the answer, it all has to be in sync for best results.
I bet leatherman's ute represents this approach. Mine is an attempt to do so as well.

Plenty at Thunderroad only have part of the solution implemented. Lots left on the table IMO. Some as simple as an tune tweak (Pah & Goldy - restrictions)
Others unoptimised combo's

I think stevie already has a carb intake

[ringram]

So he will be looking at runner length and cross sectional area's, plenum size etc then..

That's easily sorted. You should have run in the left hand lane, with the bump.

As for stopping at 175mph, is that throwing in the towel?

Ive had a carb intake for years, TBH it was mostly because I liked the look, and practicalities for 2 inj per cylinder. Hard to weld and adapt plastic.

I'd sooner run an intake with longer even runners and a large plenum if a good one existed that wasnt 24ft tall ( and doesnt cost 24k )
Edelbrock for the money isnt bad, but the plenum is far far too small.

Now if this 3D printed model ever makes it to the shelves at reasonable cost...now you're talking.
I'm sure with patience and some tube it could be fabricated from aluminium though.

You need power more than torque to pull speed. Yes you need both, but at that upper end, power is the key.

IMO if peak power is as low as 5k, something is wrong.
