well after a great day i thought id let everyone know how we got on....had some very interesting reults, some slight dissapointments and some very happy owners.
we had a good showing fro mthe mini boys with alot of the other non mini owners loving the old skool turbo terrors.
i hope everyone who attended agrees it was a great day and a proffessional venue.just a shame their AF sensor had broken.

Dan your 1275 put aout a solid performance...Daves and rich's car were even better in the flesh, very impressive work..along wit hrobs beast of a mini getting all saucy with its bonnet off all day *happy*
ill let the TM members fill you in on their own results as i wouldnt want to get my info wrong :)
but the other cars in attendance went liek this (flywheel bhp figures)
LEON CUPRA... 256 (jamie was abit dissapointed)

IBIZA CUPRA... 191bhp and spot on with the mods(ko3s turbo coming soon)

ASTRA GSI 225bhp about 40bhp downj on previous (some boosting problems and crap fuel saw to this)

FOCUS RS...267bhp (he was over the moon with this(new manifold on tis way)

S2000 222bhp revved forever

BMW MINI COOPER S (Supercharged) 151bhp sarah was alittle dissapointed but if her boyfriend has his way theres a decat system and some tweaks on the way

PUNTO TURBO...130 (sean was o kwith this ..but boost was all over the place, not mapped properly..i can see me under the bonnet of this car soon)

which leaves our TM cars
CRX
MX5
DAVES A35
RICHS TURBO VAN
DANS 1275
Dans Dad MG TF

ill let these boys take it from here :)

Nice to meet like minded people on a sunny day, doing things we all enjoy.
Had an entertaining drive home.cross country (logged 130 miles , so you know I didnt go direct) Not going to talk about power outputs except to say I was not the lowest -that honour went to a non turbo car anyway.

Ill do it again sometime when Robert has had his wicked way with me (thats the A35 talking , of course )

It was a great day, thanks for inviting us.

I'll say is it was good to meet a few of you and check over the cars.

My power run didn't go according to plan as for some reason I had a binding brake that decided to manifest itself today on the drive over so my figures are all over the place. The CRX made 163bhp but with 66bhp transmission losses, this is not right, so we didn't bother doing another run.

The thing pulled to 8960rpm according to the print out - Feck!

I'll let the owner of the car with issues tell his story, but I hope its a simple fix.

All in all a great day. Sorry if early on I wasnt really with it, I was hammered the night before!

Thanks for organising our side of things Ben, it was well attended and a great spread of cars plus it was nice to meet up with other TM guys as well.

Over the winter, I'd made good progress with the Megasquirt mapping and boost signal re-plumbing which had stabilised the boost and ignition issues I saw at the TM RR day last October. So I was hoping for reasonable results.

I'll add a link here to another thread with the issues I had when I've downloaded the pics - it was definitely not my day.

My first three runs at 8 psi 'Low Boost' went reasonably well but the van was well down on power reaching about 108 despite noticeably better to drive and with more power than when we recorded 130 last October. Plus the transmission loss calcs on the RR were all over the place, not just for mine but a couple of others as well.

The problem came in the final run where I made an error of judgement and used a 'High Boost' setting I had not run on the open road before and in hindsight was a fuckin stupid idea.

This took the van to 17 psi which despite pushing the engine to 147 brake and 160 lbft, it was not happy about and finally let go with a plume of grey smoke and the transmission case breather doubling up as a cloud machine.

After letting it cool down, we ran a compression test and immediately diagnosed No 4 pot was only running 25 psi when pots 1-3 were at 160-170. Further inspection revealed water droplets on top of the piston so Robert and I thought the gasket had gone.

All I'll say is I've stripped the head off tonight and a 'head gasket' could not be further from the truth ........ gutted.

Link posted below with phots of the damage and the MS log sheets of the 3rd and 4th runs but suffice to say it's an engine out job.

Shit happens.

Big thanks to Rob H for trailering me home.

Hope to be back some time in late summer but realistically with all the DIY I've got on at home, its looking like a winter job.

Richard.

the spell casting much be getting worse as ive been struck down with the much lesser "crossthread demon" spell today....the previous owner has proven yet again he was a completley monkey by apparently cross threading not one but 3 of my wheel studs., and half of one of them was missing...f'ked 2 studs while he was at...was swapping my front wheels to the back as the tyres were getting abit worn.. normally id get upset over this but in light of recent "melting issues" feels quite insignificant so ill make do with a mild rant haha

Thanks for a good day Ben, shame yours wasn't up to the rollers.
My 1275 came out at 60 bhp at 6000 rpm, so reaching peak slightly higher than the last time I had it on the rollers.
have a look here...
http://www.turbominis.co.uk/forums/index.php?p=vt&tid=326405

My dad's MG TF came out at 149 bhp so about 10 down on factory quoted power.

Richard, I hope you get the van sorted and it doesn't end up taking too long, would be nice to see it running again soon. Such a lot of attention to detail on that van.

Can anyone make sense of my print out?

It seems riduculous.

Here we go-

163.6bhp@8890 rpm with 95.7bhp at the wheels
97.6 1bf.ft @ 8595 - which is ridiculous when it should make the torque when it hits the vtec cam.

66bhp transmission losses.

I'm pretty sure the brakes are not binding thinking about it, as the pads are just catching the corrosion lip which can be easily sorted with a hammer.

I don't believe for a second a de cat pipe and exhaust will add 13.6 hp to a 130k engine. The figures others were getting seemed low so the rolling road is not optimistic.


Thoughts please - others seemed to be getting some silly losses too as well, so who knows what I really got. I may just try to find common loss figures for vtec engines and then ad that figure to the wheel hp figure.

What I heard was that if you did not dip the clutch and put the car in neutral immediately after lifting off the throttle, the RR computer was adding in the drag from the engine as well as all the drag from the transmission. This obviously skews the results.In my own case they were suggesting that I had 23 bhp losses in transmission, which seems a lot to me ! and I know I dipped the clutch pretty promptly as I was 600rpm over the redline.

If you ask any RR operator he will tell you that nearly everyone says that they thought they had more than they did -which applies in other spheres of life too, I hear !.

Dave / James, my inexperience of these events in nothing to go by but when I asked the same question, I was told to leave it in gear to the point just after the power curve tailors off but then close the throttle and press the clutch down and hold it there and allow the rollers to coast to a rest.

I was a little concerned to do this - I'm sure it doesn't do the thrust bearings on our A series cranks any good coasting down with the clutch pressed in from 6500 rpm (and about 9000 revs on James's VTec !).

Including losses of an unbelievable 60 bhp, my 17 psi run gave me 173 bhp and 186 lbft torque which is clearly barking. Taking the losses from the first 8 psi run, the figures we settled on were losses of 26 bhp (compared to 18 brake last October) and a power figure of 147 brake (before going pop !).

I think 60 bhp losses is the RR computers code for 'figures do not make sense so lets use a common figure' as there were about 4 of us with exactly that.

23hp is a fairly average transmission loss for a Mini. Dont forget that it also takes into consideration the tyre width, tyre compounds, tyre pressures, wheel bearings and brakes if they bind even a little.

66hp losses on the other hand is some what rediculous. I would be staright in there after the run feeling the tyres and wheel hubs for excess heat.

i must admit i was also alittle concerned initially that the RR was faulty due to the first couple of cars falling abit short, but then had the focus rs, ibiza and s2000 all pretty much spot on ... so i guess everything must be legit.. i agree that if it was accurate tho 66bhp loses seems pretty nuts

I think I will have to find a private road then, to see if anything is getting hot after a high speed run. It definately does not feel like anything binding when driving, braking or accelerating. when cruising at 60 ish it doesn't require any excess throttle.

I'll jack the front up and check everything spins freely too before and after the enthuiastic run.

ben , what happens is , if you dont coordinate the backing off the throttle correctly with dipping the clutch ,you get the absorber on the rr flips onto the neg side of strain guage ,and a little peak of losses from the engine braking gets recorded ,hence the 60 bhp .its why its a good idea to let the rr operator drive the car .

sometimes a dodgy rr will ,to increase power and make the customer happy ,tap a little pressure onto the brake pedal ,this increases losses and makes the graph higher .

I thinking was more a case of: "if you or anyone else have any problems give me a shout as my trailer is stored just round the corner from the rolling road"

Well, Who knows how much power the honda is making. It would have been nice to get a base figure before I start tuning it though. I layed my foot out today and it definately has more then 100bhp at the wheels. The mini had 76 at the wheels and it would have destroyed that despite being 400kg heavier.

Nothing was hot at the end, so no worries. Lets hope it passes the MOT ok tomorrow.

Theres some nice pics there by he way. Love the A35 on the rolling road!

Cheeky begger! Given how long your van took to build I still have 6 years to get my clubby finished and it will still have been a quicker build than the van!
