No you are not you are relaying someone elses opinions! The angle the gasses have to go through to exit the head are greater than the angle between head and first part of manifold so how do YOU answer that? or do you need to make a phone call????

Phil,
Please explain to me how it being a competition engine changes things
?
Please also explain to me how your engine would achieve 600bhp at 2.5 bar (on a 2wd manifold), if said 2wd manifold is found wanting like you say it is - surely it would blow up at that kind of power due to the shonky manifold?
![Surprised](https://passionford.com/forum/images/smilies/bigcry.gif)
And to finish, can you explain why Lee's has not blown up, despite being MAXED out in fifth gear?
Also, Martin answered your question as to why HE didn't use the 2wd manifold on his car - THE TURBO HE HAS WOULD NOT FIT WITH ONE (learn to read
). Even the Swedish tubular manifolds that we do were not sufficient and had to be fabricated from scratch to give the clearance
.
And there's more
! If you read the post by Weegie (who sounds like it is Colin from AVA
), it sounds like they have measured the back pressure INDIVIDUALLY per cylinder in the 2wd manifold, along with the EGTs and NOT found it wanting - your response to that please?

We're using the tubular manifold/external waste gate to try to eliminate what may have been one of a number of causes for the failure, also machining the oil spray jets directly into the block. After this, if it goes again, fuck knows what is causing the melt down.
The only difference between my engine and Rods engine is the crank. The head, port sizes, valve sizes are exactly the same, rods and pistons too. So the only thing that can be causing the failures must be the 2wd manifold and internal waste gate, or the oil spray bar which was checked for alignment and flow which proved to be fine. So, it's trial and error it would seem

I assume you can expect the same gains and driveability on a cossie as you do by fitting a tubular to a FRS if so well worth the money

Lee's wernt more than 550bhp...not 650+ which would be very risky.
Why people build huge budget engines and stick to stock manifold is beyond me.

Ade,
I sincerely hope you resolve the issue, and come back, faster and stronger for it
. I have no doubt that Mark will crack the issue and it will end up being something silly
.
Given the power levels you are running compared to Lee's (not far off each other and both using a GT35), I personally think it is more to do with cylinder pressures, as the only thing that is RADICALLY different to Lee's car from yours is the compression ratio. I'm not sure what you run, but Lee's is the usual "shonky old fashioned c/r", whereas I believe yours is much higher?
If it was me, I would be building the engine IDENTICALLY and covering the particular thing that I "thought" it was with sensors to either establish the cause or eliminate it (measuring the back pressure and EGT levels in the manifold). Guessing at it has cost two engines so far, so as you say, fuck knows what happens if it lets go with a tubular manifold on - you're still none the wiser
.
Also, with Rod's engine, him using a bigger turbo, means that there is much less back-pressure, so this helps things a LOT. Also the NOS makes a big difference with cooling, so that's two extra things where Rod's differs....
Good luck and keep us posted
.

.......the angle in the manifold as it comes out could cause it to go back in to the engine under extreme pressure causing HEAT...note COULD...the tubular ones all come out straight.
Its a possible flaw at 600+bhp and these are expensive engines..hence i would limit to 550bhp on one![Raz](https://passionford.com/forum/images/smilies/tongue.gif)
..also get over yourself re hi comp

Ade,
Excellent - hope the changes made resolve it
. I didn't realise you ran such low compression
, so is unlikely to be cylinder pressures...
Damn, I'm curious now - I think you should put the 2wd manifold on again and measure EGTs / BP on the manifold on the dyno and then switch to the tubular one and do the same - this will confirm or deny once and for all your suspicians. Changing too many things at once - the jets AND the manifold, and Phil's just going to say it was the manifold that cured it
.
I'm keeping with the 2wd manifold, as I will also be sticking with the shonky T4
.

If it was me, I would be building the engine IDENTICALLY and covering the particular thing that I "thought" it was with sensors to either establish the cause or eliminate it (measuring the back pressure and EGT levels in the manifold). Guessing at it has cost two engines so far, so as you say, fuck knows what happens if it lets go with a tubular manifold on - you're still none the wiser
![Sad](https://passionford.com/forum/images/smilies/icon_sad.gif)
Also, with Rod's engine, him using a bigger turbo, means that there is much less back-pressure, so this helps things a LOT. Also the NOS makes a big difference with cooling, so that's two extra things where Rod's differs....
Good luck and keep us posted

Phil,
Yep, but it's STILL faster than your shonky shit
. There is absolutely NO point (IMO), in chasing NUMBERS unless you plan to do top speed runs, drag racing or similar.
I want my car to be ultra responsive and kick butt on track - and this is what it does - it punches well above it's weight and is a complete package.
If I wanted to, I could build a high horsepower engine, but all you have to do is speak to all the people that have fitted huge turbos on their cars in the "chasing numbers" game, and then find they have regretted doing so, having made the car horribly peaky.
To be honest, a well sorted T38 car will destroy 99% of road cars and do the same on track if it has a well sorted chassis. Who cares about the 1% of cars out there - how often are you likely to come up against them?
It's about the WHOLE package, not just the engine - but you have NEVER understood that...
. I would rather have a totally reliable slower car, than an unreliable butt-kicker, that you were scared of breaking things. Too much power gives ever diminishing returns - just look at the transmission woes of ANY Cossie going above 500bhp - they're always destroying clutches, gearboxes or diffs - where is the fun in that?
Bragging rights and that is IT
.
Yep, but it's STILL faster than your shonky shit

I'm not sure what you run, but Lee's is the usual "shonky old fashioned c/r", whereas I believe yours is much higher?

Thanks Martin. The other pistons were like brand new, still had numbers
1 - 4 on them in marker pen.

Mike for the first time in your life you actually sounded intelligent.
You are right and i will be sticking to 2bar and hopefully reliability should need no other mods exept to sort out the cars chicken pox
