I'm not sure you've ever revved your car out in 6th gear tommy? Probably not...

post 6, read what you original wrote

cant say I have ever revved it out no, not sure what that has to do with your retarded statement in post 6 though

JVGlanza has a point. You could have 1000bhp in a Fiat Panda. Whilst that may see you doing 200 mph in a suitably geared car in the panda you'll only ever reach the rev limiter in top gear - say 105 mph.

Paulo P and tubby tommy also have a point, you'll only reach top speed if you have the power to do so.

You're both right depending on which way you look at it. A opinion does not make you retarded lol in fact having an opinion would suggest that you're not!

read the post no.6

totally incorrect.

it says "Power has no bearing on the top speed, just gear ratios the only thing that the power will do is increase the speed that you get there"

so if you had a 20bhp mini that was geered to 200 mph it would get there then??


I responded to post 6 nothing more

And exactly donnie, no one is wrong. Or "retarded" and there Is no need for the name calling. And I will apologise for rising to the bait and doing the same, no need for it at all.

Different points of view and both are right.

Although tommy you are still slow

according to your post no.6,power has no bearing on top speed so we all are as fast as each other given we all have the same gearing

so we are all slow, but one of us is retarded and slow

the difference in this argument is you cant prove im slow, but I can prove you are retarded as its there for all to see in post 6.

I think an interesting question would be, How much power would an impreza need to red-line in top gear. I guessing with the aerodynamics of a breeze block quite a bit .

Out of interest would a 10hp engine be capable of carrying the weight of the car and hitting 200mph as per the gearing?

If you can't hit the redline , You can't hit top speed on the gearing, So theory says?

you need the bhp to overcome the aerodynamic drag so it also depends on the car.

its not a simple as big bhp and gearing, the design of the car also has a bearing on the top speed.

What I can say is that my 265 Bhp WRX PPP is slower over a ton than my 540i was. The 540 was like a steam train, relentless. I would think that my WRX would need another 50 Bhp or so to pull like the 540i did at those speeds.

im not surprised at all that the beemer was faster, more power and torque and probably better aerodynamically

Yeah I still miss that car, one that I wish I never sold. I stuck it on the Dyno at SSR, it made 305 Bhp and 330 ft lbs, stock. And all that was only going to one pair of wheels vs 4.

I've pissed 167 in my classic with a uk 6 speed, think it would touch 175 but it was raining and didn't want to risk it.

To answer the op question. Standard Rb320 @316 bhp has a top speed of 158 mph according to the stats from prodrive. Im not sure if that was limited with the ppp map or not. The gearing would at 7000 rpm in 6th gear be 183.4 mph. My power should be around 370-380 bhp and i have seen 155 mph on the speedo. It was still climbing and i had plenty of revs left. I actually lost my bottle when i saw the ally bonnet moving around in the wind lol
Interesting.....

So if the tmic and scoop were eliminated, and fmic and reverse scoop fitted, the potential engine damaging issues would be removed and the geared top speed could be acheived? With the speed limiter removed?

Would be a step closer though?

Get rid of the ironing board, a bit more aerodynamic?

No need to worry about charge temps due to fmic, and a decently built block to handle the power and revs required could sure help use that extra bit of gearing thats left.

I could, of course, be talking shoite here

Put very simply you need the power to reach the red line in top gear If you don't have the power you are going to max out way before you reach the red line.

Is that simple enough?

There is a certain white sierra sapphire cosworth knocking about that is owned by an oap...

That thing has the power and the gearing to hit 206mph over a mile at bruntingthorpe, now i cant remember the exact drag coefficient but it isnt great. Its got 800bhp and a good shot of nos to get it there too.

So basically, you need power, and gearing, and big ***** to go FAST....

Me, i hit an indicated 135 in mine a while, no idea on the revs but let off as the bonnet looked it was about to exit stage right....

Not tried to top it out, maybe ratchet strap the bonnet down and have a go lol.

Ps does the bug uk300 come with an alloy bonnet as std? Mine has one.

thats harsh kicking a man when he is already down. Got a pic of my bros car with the flat vent, think it will look great on your car

Rod from Passionford would love this thread. If you was to use his saph cossie as an example. A standard saph cossie with 204 bhp when new would do roughly 144 mph. Rods now has 800+bhp and does either 206 or 213 mph. Not sure what he's done to his ratios in his box. So bhp does increase top speeds

I think rod is on a tko box, and 19 inch rear wheels for the 206.
When the car is back on the road it should be near 1000hp before nos and capable of 216 i think is the plan

Martin hadlamd done 204 mph is an escort cosworth with near 800bhp. Must have a better drag coefficient than the saph.
And i think any gallagher managed 202 in his focus cosworth.

Anyway, ill stop banging on about shonky fords that have done the double ton lol

Fudgey shut the f*ck up because power has NOTHING to do with top speed LMAO
