It does make iro 230bhp! At the wheels 😬 James Su77on Se7ens

Pete From memory it was 175 lb ft torque and 230 bhp. There should be a bit more to come when I get to try the cam timing where it should be (at the moment its nowhere near optimum as the piston pockets are too small) . Also I have some different (longer) trumpets to try which I think should help get the peak power within my rev range 😬 James Su77on Se7ens

Oops Forgot to mention that bit! Track n Road in Rainham James Su77on Se7ens

I could do with a pair of front brake calipers (standard) if anyone has some they no longer need after an upgrade James Su77on Se7ens

I was at the rolling road on Tuesday getting the babe magnet mapped 😬 I have been there lots of times and am still amazed and fascinated by their attention to detail Sorted out the bad running problems and found the reason for it being a "bitch" to map! It looks as if the roller barrel opens the wrong way so my project for the winter is to reverse it and hopefully that will sort it out nicely Then I can get back there and try out some different trumpet lengths and injector positions etc A big to Steve and Steve 😬 A superb job as usual Cant wait to drive it now 😬 James Su77on Se7ens

How come I dont get spotted in my 7 but I drive someone else's 7 for 5 minutes and get spotted 😳 Neil That sounds just like me 😬 Although the very nice policeman I was talking to yesterday may disagree slightly 😳 James Su77on Se7ens

RJ Thanks but I think that 10000rpm is enough for my little old engine James Su77on Se7ens

Thanks for your kind offer ric But no Stack were very helpful and friendly on the phone today So i will post it off in the morning. Which means no car for a few days ☹️ but hopefully it will be fixed for the bank holiday weekend 😬 James Su77on Se7ens

The official story is................. I pulled this good looking girlie and decided that she needed impressing by my cars performance as well as mine so we went on a blat down some lovely country lanes driving flat out on the limiter most of the way. Overtaking everything in sight etc etc and generally being a hero After the needle of the rev counter being repeatedly banged on the stop at 10000rpm it finally broke or the alternative story............. I stopped at a friends house for a cuppa/chat etc and when I got in the car to leave,i put the ignition on and the rev counter does its reset thing it broke before I even started the engine One of these is true but I am not saying which 😳 James Su77on Se7ens

After 9 years with my 7 I have broken many components. I call this "destruction testing" ❗ To be honest the car has had its fair share of abuse, I guess, including lots of trackdays a few sprints and lots of abusive launches at the drag strip (1.5 sec 60ft times) as well as thousands of road miles all around the country. In no particular order I have broken a few clutches, gearbox(a few times), some alternators etc etc and have replaced the offending items with something which is more up to the job. Personally I put these things down to excessive bhp/revs and general abuse. Since these teething problems I have not had any failures for ages (read years) till today ❗ I feel very stupid having overlooked the need to up-rate this component 😳 but since its only 18months old I felt that it would be ok for a while but hindsight is a wonderful thing ❗ So the main point of the question is do Stack make an up-rated needle for their dash/rev counter as I have broken it in half James Su77on Se7ens

Bob You have mail James Su77on Se7ens

I just hope that Arnie doesnt see this 😳 James Su77on Se7ens

For me the most important thing about getting a car/engine on a dyno/rolling road is to get it mapped correctly so it does not damage itself and drives nicely which Steve does a superb job of! I have seen a few dodgy dyno's where they have damaged various things. This is why I will only go to Steve now! Arnie My theory on your cars power figure and your clutch issue at that time would make your power figure higher than it actually is 😳 James Su77on Se7ens Edited by - James on 30 Jul 2006 23:05:59

The results I have had from Steve Greenald are always consistant 100% And I have seen quite a few over the years. I have used quite a few places for dyno and rolling road work and have never seen it done as well. They do the job properly and are very fair with their pricing too! This is why I will only go there. They are very good with pretty much all the popular ecu's as well as more basic carbs/points/distributor set ups. James Su77on Se7ens

Steve - give Dave Edmands a ring on 07767 457359 as I think he's selling a pair of hardly used 7/21/13 A24 ACB10's. James Su77on Se7ens

If anyone's interested in the car complete with all spares and trailor Dave's looking for £25k which is £6k less than the individual costs. James Su77on Se7ens

Following a few enquiries regarding the trailor Dave will need it to take the car to HTR to get the Hart engine and gearbox removed, but it will become available after that. I'll re post at that time. Engine is in the process of being sold so it shoulbn't take too long. James Su77on Se7ens

Due to family and work commitments Dave's selling his car unfortunately. This would make an awesome sprint/hillclimb machine being well under 300kgs without engine and box whether it's got car or bike power.

This is what Steve Greenald has to say:- Following their runs the other week Arnie Webb and Dave Edmands were interested to know more about how the calcs were done. It was unfortunate that we had issues with both their cars getting the usual repeatability and accuracy of power figures, however we now know how to deal with these cars if they can make it back to us sometime. It may sound odd, but these two cars are quite exceptional and present more of a challenge to test accurately than the 733 BHP (Rev limited to 7000rpm) Ex TWR Jag V12 Group C car we tested recently. One of the main reasons for this is gearing. The higher the top speed the better as far as we're concerned. I asked Rudi at www.dynosystems.de who makes our rollers if he could pass on a bit of info as to how the figures to post this reply it may help everyone to have a better understanding of the system. Any interested parties should visit Rudi's website and if anyone wants any further information I suggest they email Rudi themselves as we're too busy to enter into long drawn out discussions. We're convinced enough of the RR's accuracy. But as with our work ethic, we wish everything we do to be totally transparent. Best regards, Steve.G. Hi Steve, RR_clc.exe: you have a) power at the wheels and power losses. b) correction factor (DIN, SAE, whatever) RR_CLC multiplies the power at the wheels x correction factor. Then the power losses get added to this. We calculate a formula for the power losses so that we can add them more accurately together and so that we can remove incorrect spikes, such as a clutch which will not disengage immediately, stuff like that. A short blip on the brakes will also be disregarded (but not a long burst of brakes). It is important that you always ensure that the yellow line (calculated by the PC for the losses) sits on top of the green (=recorded during power run). Only then is the power test valid/correct. I think that is about it. Our software is the only software which allows you to see the calculated losses (yellow) and the measured losses (green). Other systems, such as Sun "surprise" you with a result and you have no telling what they have done internally with the data. On ours, the secret is unveiled, i.e. there is none, it is a simple addition of flywheel power = (power@wheels x correction_factor_engine) + power_loss Best regards, Rudi James Su77on Se7ens

If its done properly then its very safe,very simple and works very well. The limiting factors are as Oily has stated the weak link in the engine ie pistons head gasket rods crank etc. The nice thing with nos is that it also increases torque at a similar rate to bhp. The downside to this is the clutch and drivetrain have to be able to cope with it. A nos controller is a very good way of dealing with this as it can be made to be very progressive and therefore gentler on the engine and drivetrain etc. In a 7 its probably not going to make that much difference as far as the traffic lights grand prix is concerned as most 7's are traction limited anyway. In fact will most likely make it slower off the line. Its not illegal to use nos on the road but you must have a sign on the back of the car stating it has a non flammable compressed gas inside. Incase of an accident/fire etc Also I am not sure how your insurance company would view it! Arnie When you saw it fitted to the engine in my car how certain are you that it was my engine James Su77on Se7ens

Anthony A friend has a vx engine with 12.7 comp. It runs with carbs and mapped ignition and he uses Optimax fuel. It was mapped by Steve G and it runs like a dream with no signs of det etc after a recent strip down of the head etc. As long as its mapped well as in this case it should be fine.

Trouble with the k is that is was designed with numerous flaws which should never have made it into production To be honest I think that the designers were smoking some illegal substances when they let it loose for production Either that or they did it for a laugh 😳 Surely being a bit forward thinking is not a good enough excuse for manufacturing a badly designed product I reckon my mum could have done a better job James Su77on Se7ens

🙆🏻 Sorry about the spelling James Su77on Se7ens
