s50 engined e30's

I don't think anybody does m52 stainless manifolds for e30s do they?

Not yet, but very soon

Should of known you had something up your back passage. you been talking to a known exhaust builder?

Slightly, he will be supplying the parts and I will be cobbling it all together, have you seen his welding?

Yes and its shite

I think it was an M50 designed manifold though..

The Fritz manifolds were M50 designed AFAIK. The one Dave has done (not Fritz) was done with his S50'd E30 in mind.

You make a valid point about dyno's only being useful really for before and after.. HOWEVER, Fritz's dyno is known to show consistently higher figures than it should do, hence why I would like to see it on a dyno that is known to give more expected figures.. And have no connection with the venture

As above, Daves system are not connected with Fritz - he just happens to work there. Im not even sure if he dyno'd his systems on the Fritz RR.
But yeah, I would offer my car for it to be dyno'd on someone elses RR

If Fritz's dyno does give higher figures than others, that 'over reading' (for want of a better term) will be consistent on a back to back run.
If I took mine there and got a figure of 300bhp, but it only showed 290bhp on another RR, that wouldnt bother me as long as any mods that were carried out gave the same gains on either RR.

Ah you see.. If you were talking dyno'ing yours with your exhaust and BTB, and then Dave's offering and your exhaust then it doesn't matter where you dyno it, as long as they don't fiddle inlet temps etc

I know Dave did this independant of Fritz, hence why calling it Dave's manifold.. But he works at Fritz, hence the 'not on Fritz's dyno..

I may well suggest something like this to Dave (not the fiddling bit though)

But he works at Fritz, hence the 'not on Fritz's dyno..

Thats only really a problem if Dave was to turn around and say that his M50'd car made (for example) 220bhp with his 6 branch fitted.
But if he is simply saying that for example, 'the tested M50s or S50s had a 10bhp increase after back to back runs with this 6 branch and system over the cast manifold etc', then as you say, it doesnt matter where its dyno'd. If a RR over reads by 5%, its going to over read by 5% no matter what exhaust is fitted.


Anyhoo, Ive finally got all the 5 lug fitted - been having fun , but am beginning to think my gearbox is shagged

Feck.. Not expensive, but a ballache!
