2014 Thunder Road confirmed Sat 9th August Woodbridge
Discussion
I don't understand this constant referral to cost.
Yes, for those that DIY a huge amount can be saved. Most on here don't have that type of expertise and so rely on the aftermarket companies. Thats a totally different situation, I'd be very surprised if the actual costs were much different.
Never forget that going faster is a V squared fact, both physically and financially. For those who don't understand how much it costs to go just a few mph faster at these type of speeds perhaps you should step back a bit and do some research before commenting.
It seems apparent to me that NA is limited by ultimate power V emissions/ driveability and FI with heat issues and incorrect gearing at TR.
Personally I'd love to see a 180 mph build at TR, but if Rich is running 500 whp at 171 how much more power do you all think is needed for that extra 9 mph,and how drive able would that be on the road.
That makes some comments on here a little throwaway imo

I cant say I saw any that were modded PURELY with TR in mind.
Actually I did! I fitted a £400 water/meth injection kit (which hurt me on both counts) and a £20 flat bonnet (which increased my IATS and hurt me). TR, for me, gives me an opportunity to try and make my motor go faster and push the envelope. Its all things to all men, that's the great thing about TR and everybody gets soemthing out of it and enjoys the day.

All cars I saw were full going road cars just there too see what they did. That too me is as good a comparison as you will get.
Thats true, no drag cars on trailers.fastbikes76 said:
Again, I personally am not saying the FI guys have wasted money
I did.jameshsv said:

Top speed and power be damned, Thunder Road has told me to get the 3.9 gears in sooner rather than later!
They work well but I think there limit would be about 170-175 depending on what power you have.EmmaJ said:

itnd
0.74 5th gear, with a 3.9 diff and a 6700 rev limit is 178MPH
Thanks Emmaj Would that be with a cv8 box and 18" wheels or 19" wheels.0.74 5th gear, with a 3.9 diff and a 6700 rev limit is 178MPH
What's the size of 18" wheels? 235/45/18?

I was changing up at 7k with standard rockers. Dont want to move the limiter any higher though. (At the moment)
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.

Right in the end my car look good
Sounds f???? Good
On the road it f??????? Fun to drive
So I am still happy to say I have a big v8. Supercharged car with 670
Get more cash get more power
And ditch that window spoiler Goldy, def not good at speed, it causes far to much turbulence behind the car, I took mine off a week after fitting it.Sounds f???? Good
