Honda S1 Exige Owners - Show of hands please...

Just a couple of questions for evosal and Bernard:

  1. How many miles has evosal’s 360hp car gone? I think someone mentioned that the TTS civic type R has covered 10k+ miles with no problems at the same power?

  2. Bernard, has your new 1.9L engine been on the rollers yet? How did it go?

Many thanks.

It has been on the rollers but we don’t have any power numbers for it yet. The fan used to supply air to the side mounted intercooler simply wasn’t big enough and the charge temperatures climbed to unacceptable levels. We are going back with a charge cooler.

Bernard…

you know people have been “making up” all sorts results for me

I say to you…you have no idea what valve sizes I am using, or what borestroke, and those two factors are just two amongst many that affect the result.

Think about this…the Judd engine is a very simple engine…much less trick than mine. It is limited to just 12mm lift, and 8500 rpm, it uses a plenum with a single 60mm TB and it is wet sumped. It achieves 275bhp.

But just to wet your appetite …the new head I have designed which is still a little way away has compound valve angle 36.5mm valves and should flow 180cfm…I get 159/160 from the MS2 Vulcans I am currently using - the best dva I have ever measured was 142cfm.

There are ways… if you think about it…

I hear what you say but I do know you can’t possibly have more than an 83 mm bore, unless you are making you own block as well that is. So your bore/stroke ratio is poor, not to mention the rod angle. You can stick as big valves in there as you like but if they are masked the cylinder head and bore walls you won’t gain anything. Anything over a 12 mm lift just puts strain on the valve gear without significant gains in cfm on the K.

180 cfm eh ? The standard out of the box 5 valve Audi does over 200 without any porting, and then we put a turbo on it.

You really need to go out in a SC Honda or turbo Audi to see what you are up against.

You still haven’t answered my question of long ago about how many K series parts you have left in your proposed engines. I think probably only the flywheel bolts, but maybe you’ve had to change those too.

Bernard

Dont really want to get drawn into all this but i have done 5000mls since the honda conversion and 3000mls with the s/c conversion (including 3 trackdays)
No problems other than the driveshafts shearing which hopefully now is sorted. My car is running with totally standard engine and gearbox and is coping fine so far.
It may well fail at some point but the way i look at it i can simply replace the engine for around �750 !!! how much will it cost to replace a 20.l k series ???

exactly the point i was itching to make - much better from the horses mouth so to speak.

You may see some graphs before long but you will have to wait till the book is published to see what I have done …however …your assumptions are not correct.

200cfm…at how many in of water??

What I do know is that the audi 5 valveheads give very poor swirl and hence combustion, getting mixture into a cylinder is no use if you can’t burn it. F1 designs are resolutely 4 valve at up to 94 and 96 mm bores, they are also have compound valve angles like mine.

Don’t worry Bernard - I think 270-300bhp from a 2L FI engine poor, will beat it na, and the FI Ks will show you what you are missing…

no I use my own flywheel bolts…

simon

200 cfm at the industry standard 10" wg.

Of course they are poor etc etc, they are not K series so therefore they are crap. Now where have I heard that before ?

So it sounds like you are not using ANY standard K series parts then ? So therefore it’s not a K series anymore. As I said about 2 years ago, what you have come up with (sorry, will come up with at some time in the future) is a racing engine that looks a bit like a K series from the outside.

I rest my case.

Bernard

200cfm…at how many in of water??

200 cfm at the industry standard 10" wg.

Oooops, sorry just checked and the 200 cfm is at the other industry standard pressure of 28". What were yours measured at Simon ?

Are you going to tunerGp this year?

Definately going if only to watch

Definately going if only to watch

Getting a proper racing driver to drive it for you, I hear

PS Good to see you at Cadders yesterday - your car sounded LOUD as it gobbled up the tarmac

You tapping my phone Rob

I still find this conversation funnny, im not going to the Tuner GP this year, as to be honest it seems like its a bit of a HP war.

Not going to bother now, have chatted to Scuffers and to be quite honest we have better things to do which would be more significant on the track.

Now bearing in mind my car led the time sheats for most of the day up untill 4.57pm when the event finished at 5pm is some what of an indication of how fast the honda conversion is.

As far as I know we are not bothering this year, I hope that anyone that enters does well, but it will only end up as some sort of mines better than yours senario.

Im very pleased with what I have, to be honest it is fabulous, ive not driven an audi conversion car, nor seen a high powered rover K car, even though ive heard they do exist, still its been a year since the last tuner GP, we will see what happens.

Have fun all.

Christian, with all due respect it didnt seem to bother you last year when you were running 300hp and most others were on around 250 hp

Makes me laugh too…

EVOSAL -it’s not on the list yet , but there must be an SC K for my book, if you have the most out there sc honda , do you fancy going head to head with my SC K when it’s done, on track, same day, with the same pro driver in bith for lap times and an unbiased opinion?

simon

I’m up for that too, is it going to be next year or the year after ? I would put in a proviso that you must have done at least 1000 track miles with it first to prove that it can hang together.

Bernard

Simon
By the time you,ve finished your s/c k things will have moved on again.
My next project is going to be 400 + bhp and will be ready early next year

Simon

And I would expect a SCK to be 450bhp from the off - minimum - so are you up for it?

simon

I don’t believe you Simon, how long will it be till you can prove me wrong ?

Simon

I have no problem with having a head to head with you bring it on !!! however i am only interested in entering my car in the tuner gp for a bit of a laugh, its not something i will do every year as i have absolutely nothing to gain from it and nothing to prove unlike yourself
