or you had an engine issue on the dyno?
No engine issues and no more dyno time, this will prove it self at Brunters.
We thought at the time that we had a issue with either CDI unit of coil packs and to be truefull the engine proved it self on the Engine Dyno as you can all see by my Figures even thou some of ya think they was made up.
After looking at all the data that mark stored on his labtop he noticed what was the problem and now that has been fixed.
So roll on Brunters

Question:
MIKE´s engine and MAD engines, do they use the same cams?same turbo? or do they use the same guy for porting the heads?
Doesent seem like it, so thats why the engines performe differently
To me it looks like that YUM´s engine uses cams/head-porting for track days ans mike´s engine more like straight line setup, am i wrong?
If u want to compare the 2 engines, then use the same turbo/cams and c/r then it is up to the porting, mapping and timing...

Its possible to improve the det properties of the YB though, most notably through different piston designs, but ultimately it will never be an EVO motor so will never have the same optimum CR as an Evo does.

Thats pretty rare round here.
But saying to two people "build exactly the same engine then we can see who builds it best" is a bit pointless as ALL these people can build the engines to a very high standard, the difference is NOT in the building of the engine, its in the spec, thats the whole point!

My opinion is that marks choice of cams and head specs has a FAR more pronounced effect on the results than the temp does.
I suspect the extra functionality of the autronic, and especially the extra resolution on the ignition map is helping.
Are you prepared to divulge the loads sites chosen to map this engine with (its on L8 isnt it?), it may well speak volumes about why its failing to perform as well as Mark can make his!

I disagree, MAD engines are absolutely NOT made for balls out straight line power.
I know how ridiculous that may sound to some people but its the truth IMHO
Mark is far more interested in a huge spread of torque then he is in a peak figure, and i think most people in this thread will understand that (with correct gearing) peak figures are where its at for straight line speed.
Look at Rod's car, its WELL past peak torque at the RPM it pulls at brunters, its NOT ideally setup for the task, its setup as a combination of top speed consideration and then far more focus on being a driveable road car.

I can read just fine, but havent sat down and "revised" for a test on this topic, so was assuming it was on L8 as i dont remember what was written 7 pages ago.
Fair enough though if its on T6 or whatever? I dont recall what was said earlier about that.

It is indeed Dave.
We call it the "Beast" because on race fuel it made all the sixes .
T6 with a T66 made 666bhp . I think Tony should be scared

Hang on, I might be wrong.....is that the turbo?
![Red Faced](https://passionford.com/forum/images/smilies/icon_redface.gif)
T66 Turbo
666 Bhp

Chip...you have to remember the vast majority are not interested in top speed runs...also i feel many stage 3's would melt doin 30seconds held at Brunters!..My car for example even if i never get it tweaked to perfection it wouldnt go wrong purely thru application...the odd mental run on the road thats it..doubt i will ever see 4th gear past 6k

Phil, wether people are interested or not is actually a VERY valid point in terms of if it will be reliable.
Take Doug Stirling who has posted in here for example, i believe that both he and you would probably be safe with a high comp motor as I know he (and it sounds like you) wont EVER hold his car flat out for a massively long period of time, he loves the kick of the acceleration and is very much into fast cars, but he enjoys them whilst still maintaining a degree of mechanical sympathy and respect for his license.
So he could be built a 8.5:1 YB with 600bhp and never melt it and it be totally reliable, but if he lent it to Si B for the day, it would be fucked.
This is why its important to have a good relationship with your tuner and them know about you and what you use the car for IMHO as it effects which compromises to make.

I wish i could get a PROPER answer to my question though. Have been asking for 4 pages
![Surprised](https://passionford.com/forum/images/smilies/bigcry.gif)
What more info would you like that i have given?
Differences in dyno setup
Location of the temp sensor when on the dyno
Correction Factor of BHP and LB/FT and the fact that the scale of correction is the IDENTICAL for both and Mike saying it is similar BUT NOT IDENTICAL.
None of that really explains why a 600 bhp engine with a big turbo, 2.3 bar of boost and a pukka managmenet system only produces a peak of 463 lb/ft torque. It has to be something mechanical in my mind, maybe a head that is ported too much or incorrect cams. I know i will get shot down and be made to look like im slating a non MAD engine, but this isnt the case. I have an interest in how things work and why they work. For example, Daves old spec 470 bhp and 430 lb/ft on a t38 with mad spec cams. 130 bhp down from this T66 equipped 600 BHP engine but only just over 30 lb/ft down. I know full well that an engine can make 500bhp/500 lb/ft on a GT30 turbo with the correct spec head and cams of course. So i ask again, why is the torque figure realtiveley low for a 600 BHP engine? Is the BHP figure inflated or is the spec of the engine just not correct for mega torque? I cant put it any clearer and I am trying to make it so NO ONE can read this and think Rich is just trying to make another tuner look bad. Im not

So what was the problem in your mind Ian as to why it did this if you dont mind me asking,
Because i know of another High comp engine from Paul and if my memory serves me right that eventually let go as well ( but i may be wrong on this)

It mysteriously commited suicide the very 1st time I drove it after having a GT35 fitted to replace my T4. Then after a little resuscitation in the form of a head gasket and major head surgery, the very next time I drove it, it completely destroyed itself. Though I did salvage 2 useful parts - the filler cap and sump plug!
Old news now. If you want details pm me and I'm more than willing to share the full story and advise you on not what to do - plus I do not want to detract from this otherwise excellent thread. Debate at its best. God I love this place!

My guess (well any opinion other than Harvey's is a guess as only he realy knows what he did or why he did it)
The spec of the engine isnt designed for mega torque, its designed to rev its fucking tits off for long periods making big power and still being reliable, hence the solid lifters etc.
Again I will say it, its not wrong, its just a different approach.

If you wanted an extra 1000rpm of useable power coming out of a bend you might as well
But for a road going cossie im with you mate, huge midrange torque is awesome fun (unless you are the tyres, lol)
