shhh !! would 200cc knock over 1000rpm off what most othere peoples are coming on boost at.

Rick

Can do mate, it's a longer stoke and totally different characteristics to the 16.

i see usually, on 1.6 cvh,

4wd cossie t3 (Complete), Tested using brakes, so held under full load.
2000rpm = 2psi
2500rpm = 5psi
3000rpm = 10psi
3250rpm = 18psi
3500rpm = 28psi


Std T3, and a stg1 T3 on same engine, just turbo swap and setup, Gets full boost at 2600rpm.

Rick

I remember u doing a load of testing Dan - i concur with those figures

rickbartlett

really? thats really low to be pulling hard at that rpm

crazycage

yes but it was far from standard and it was a 1800cc cvh.

I havent done anymore testing on my own car since, due to it being stationary for nearly 16months.


All turbos tests was carried out on my 1.6cvh, carb'd turbo, P+F head, within days of each other, in same weather conditions, (dry, late night), with accurate gauges (tested, rpm and boost) Same ignition curve and AFR.


The 4wd cossie turbo setup was tested on

- a std and kent35 cam,
- with different actuators, and preloads,
- different boost controlling
- and with no feed to actuator at all on 2000-3500rpm test, where i backed off once 28psi was seen.
- with 2 different ex housings, one with worse cracks than the other, but no difference, (but do have a non cracked one to test on it once i get on it),


These were tested as above, but with std ford cam.

The Turbo Technics Stg 1 turbo was in perfect condition, with no failures in ex housing.(full boost = 25psi)
The Std item was a well used turbo with many cracks in the ex housing.(full boost = 25psi)
