I thought the hat said Mr. Turbo? I know, it's a chipindippindude thing
isn't it?
PR = Po + Pb/Po
A 2.5bar PT can control boost to 2.5bar = 21.75psi, the claim is 26psi
=2.79bar. So, either you are controlling it with another source (claim: you
aren't), or you don't have 2.79bar (claim: you have). Ok, I'm confused,
which is it? If you are using a STOCK spring with a 2.79PR, then you should
reread Maximum Boost, "Wastegate Cracking" page 149 (or my post on it is in
the archives as well).

2.79bar is the claim (not mine), 513CFM is the physics of that claim to a
134ci motor. Modifications are irrelevent. Don't need them.... PHYSICS

His is the simplest, and what most here can relate to. It seems apparent by
some of the posts that owning it and understanding the printed words aren't
always related concepts.

If I'm not mistaken, most of these are yours, sir:
* box mod gives 26psi in 2nd thru 5th
* 2.5 bar PT (given)
* box mod gives 16+psi in 1st gear
* .5 PD accross modded IC
* Audi --> RS2 gets 310hp @ 460CFM (given)
* 1325 EGT
* Audi --> MC motor = 134ci (given)
* "... An RSR turbo, a Ned Ritchie turbo, blows the RS2 into the weeds"
* "... will outrun just about any other MC around, especially the RS2
wannabes."
* Stock Wastegate Spring (new)
>From them I extrapolated only the basics to the claims in accepted engine and
turbo theories, math and physics. Maybe you can explain how 513CFM goes thru
an MC motor. Or how you control boost to 2.79PR with a 2.5 bar PT box with a
stock spring? Accepting the usual 1.5 factor for airflow, 342 hp? It seems
to apply well to the audi motor cuz the RS2 is really close 460CFM/1.5 = 306,
so is the claim 342hp or something else?
Something isn't right, cuz someone is claiming that laws of physics and math
don't apply. What's with that? My calculator just printed "error" again.
Some of the claims are starting to contradict themselves here...
