But my first comment was not how it was put together i was meaning the build spec really.
My engine was built to rev - steel components, ARP throughout, fully balanced, peened, knife endge etc - the head was optimum ports, valves, matched, guides, solid lifters, custom cam and would rev out the std gauge.
Transmission was uprated clutch in a custom box - a mix of S1, RS2k (i think it was), and Diesel final gears

What I mean is a normal 105bhp XR3i will never hit the limiter in 5th and do 150mph no matter how well it's put together
lol
But your build spec is another story, very impressive to hit 150mph in a NA CVH![god](https://passionford.com/forum/images/smilies/dieu.gif)
Would love to see how and were it makes power, dont supose you have a graph do you?

Regarding the original context, he was probably suggesting that based on the fact that he has been 'off the clock', so assumed that to mean about 150mph. Mine used to reach that point with another cog to go.
Fact is, the original speedo is a good way out. From all the top speed events I have done, I can tell you that most 'tuned' RST's do 148mph and of course you need to make further changes to alter this. Removing or raising the rev limit isn't really enough, since you need to be able to pull past 6250 anyway, which most 200bhp RST's won't really do. It's all academic anyway, because the chances are in this case that it was as I said and not that he has carried out a proper test with calibrated equipment.

As above all guestimates readings of the std gauge

love that 3 door mate BRAMMER. ALSO ABOUT THIS 150MPH thing i dontsee how it makes sense i have around 200bhp on a zetec 2.1 engine t3 turbo running 14psi etc dont no how i managed to have it at 140mph so quick. not sure but it would have done a bit more maybe 150mph which would have ben way off the clock, dont understand as in mags rs turbos running alot more bhp etc only get like 140 tops unless its really beefed up which get like 145 etc,,,, wondering if the ford guages are obviously lying a bit lol maybe if u strapped a proper speed guage ull get 20mph lesss or so ???????????

well fuck doing 150mph in a 26 yr old s1 lol i will stick with standard gearing lol
but out of intrest what would a 280bhp 1600cvh running t34 ect and cts stage 2 box and 205/40 17s do top end.... i think its got s2 gearing with ib5 bits ect
TRY IT AND LET US KNOW LOL im guessing around 155 maybe 160
i know someone with 1 running 310bhp he got 165 on proving grounds but not sure about his gearing

Part of the fun doing stupid speeds lol.They were built for 0 to 60 rather than top speed.The more bhp you got,the faster you get to your limiter.Not enough bhp,then you wont use all the final drive.Use a Sat nav if you not got correct equipment.

oh well, my s2 hit off the clock on the m5 toward taunton one early evening in perfect conditions
it was still picking up...slowly...
it was only when i thought the sunroof was about to flip out and the glass cave in that i actually let off!
