Excellent stuff Graham, great power to. What's the current spec ?

Hi mate he's doing well, in his usual spirits had to wait about 3-4 weeks to get booked in but then I did want a saturday. Great price for all the work he put in.

You guys doing a shoot out in 2014?' I think he's all up for it.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

try 50 50 water methanol ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

before or after the charger?

personally id research the effect on the rotor coating , but I would prob run it through the charger anyway!but im like that lol.

Firstly, congratulations. I expect that this will be a great car to drive with lots of torque.

Well the fuel hasn't effected them since 2007 so I would just leave then. It would mean a proper setup and pump rather than my home brew headlight washer pump.... I wasn't going to bother with a progressive controller with such little boost, but open to better ideas...

The thing that stopped me with adding the meth was it will change the fueling, so if it runs out I will be a bit lean. I guess there might be some trick way of sorting that with the ecu, but I'm not sure. It all getting a bit weird science already! I was also a bit concerned about back fires when running the carb hence why I only went with 100% water the first time around...

Hi Paul, if I had the fab skills or could have got a turbo kit that meant no body mods I would have gone that route.
If I'm honest it's all a getting a bit complex already with the simple injection I have now, god knows what you have to sort out....

The other thing is I'm not too sure if I want much more power, I know that's a stupid thing to say on here, but my merc is a case in point it has too much power for the rear wheels/chassis.

I think the extra power has come from the old carb being way too small at 38mm I did some fag packet calcs and the flow rate was way off, the new 45 mm has sorted that.
The injection kit has helped with the engine being smoother to drive, ESP at idle. If I'm honest the software is a little clunky and it's missing some simple features that the mj had, but saying that it was a bolt on kit at a great price...

It's all of the correction factors that do my noodle in, they can effect things across the board, and there is no way of knowing what's active when...

Just need to sort the few issues and book it back in for fine tuning.


Can wait to see this new engine of yours..

Oh as a side note, I was thinking Im close if not at the max for my setup, except for maybe a few more revs. I say this as I have been using pauls figures on his road going 998 being the bench mark for a road engine.
Iirc he was running 12psi on a 998 overbore and with all sort of very efficient trickery, link Siamese injection, tuned inlet runners, sorted cam, plus being a turbo has the advantage of an ic. I think Paul hit hit 120bhp on northampton rollers.

That's now an old benchmark from an engine conceived 6/7 years ago. Actually a standard ish bottom end and head with a mild, unproven cam. The inlet runners were not "tuned" although in hindsight they were significant. Injection alone does not make any more power.

I think that I got 112hp at Northampton in 2009. But that was with a soft rev limit set at 5700rpm. Later simulations identified that the short centre exhaust manifold runner was holding it back.... a lot.

I'm expecting significantly more from the new engine, simply by maintaining the same torque to far higher revs by using a better head, bigger turbine and tuned length manifolds.

I think you could also make a lot more power from that engine by inter-cooling and port injection, although that would involve some complex bypass gubbins as well.

Stay with it

Okey dokey... After some chatting to our very own Robert. I was thinking obout the two motors as I Chnaged the fd on the new gearbox, the old engine had the standard 1969 diff where the new box has a 3.1 Robert kindly explained the differance


yo to the graham!

higher the diff the higher the rd speed on the rollers.

so the greater the losses.

eg ,

take a 200 bhp engine with a 3.44 diff, at 6500 it may be doing 115 mph , so losses may be 18 bhp .

now stuff in a 2.95 diff , rd speed at those rpm could be 130 mph,so losses now are 30 bhp .

same engine reads 182 bhp atw ,and same engine with high diff reads 170 at wheels .

feel free to copy and paste this into your thread... it saves me explaining it lol

hope it made sense

regards
robert

I got a couple of hours on the car the other day.

I have reset the vr sensor to .83mm and moved it over a little so it's dead centre of the teeth in the med pulley.

I have started on an oil cooler install, I just need to make the pipes up.

I have re-routed the throttle cable but it still feels a little slow to return once attached to the pedal. I wonder if a lighter pedal would help? Maybe one of those dsn alloy ones. I have tried an extra spring.

I'm going to change the main positive connection from the battery to a thicker cable that will then be used to distribute via the aux fuse box under the dash.


It's booked in for the 8th of feb for its map fiddling mainly around the cruse section of the map.

I want it all sorted early so that I can use the car this year...

Ok I have fixed some of the little issues.

- throttle cable routing
- lighter throttle pedal so the throttle spring snaps it back.
- re wired the main power
- installed the oil cooler and stat just need a smaller filter

I'm not sure about these aeroquip push fit hoses but they were very difficult to make so I guess they will stay together.. I want to change the brackets for some alloy but will do that later

i can say that i will be using those type "push lock" fittings and knowing first had how hard they are to assemble im not worried

lets just say i put the fitting in my bench vice then lightly sprayed fitting n hose with wd40 (like the shop said) then put all my body weight on it trying to shove it on

i swear you could pull a car with it and not pull them out haha

the shop said just use the proper hose (supplied by them with fittings) and they will hold way more pressure than you should see after all they are earth moving hydraulic fittings and hose

by the way ive not ran the engine with these fittings yet !

Yep they are a bit tight to get on....

This turned up in the post... It's scaring me

come on then what is the stuff?

Water/meth injection by the looks of it!

Yep it's a 50/50 mix. I'm not sure about using it.... Flames that can't be seen worry me

Where did u buy that Graham ? When I was looking for some I could only find suppliers in the U.S.

I bought 25 litres of pure methanol and mix it myself.

It wasn't fun driving home with it in the boot of the mini driving home along twisty lanes in the wet :/

In the 13's at last!.. Just

Only drive the car at night or in a darkened room lol

Ah ! Looks like they've only been selling it since Feb last year, that's why I couldn't find it.
