Smudge's ITB'd 190PS (almost) in further ABF 16v dyno development. 03-06-11

Apple's legal department will be in touch shortly, regarding your defamatory remarks about the iPhone. Messrs Sue, Grabbitt and Runne asked me to state clearly that the iPhone accelerometer is certified *even* for 8v use.

 

Got one of those apps, (works with diagnostics port) and will be testing it on the Ankor saloon. If it is good on a car that can turn over on its roof with twist, it will work on *vs and Diesels .

 

Dynolicious, or a different one?

 

There is this one but not sure it give a trace like the g tech.

So Smudges engine spec appears very similar to VWsinghs with the exception of the ITBs and 4-1 manifold (rather then 4-2-1?). Or are there other significant differences?

Is the difference in top end of the torque curve purely down to the ITBs? Do you think the 4-1 manifold has much effect?

Having mapped both engines, do the AFRs or VE tables give you more insight into how the 2 engines are flowing throughout the range?

 

Smudge has ITBs and a ported head.

VW_Singh has a lighter car and a lower ratio diff, which should allow a more aggressive ignition curve.

 

The ITBs allow the top end torque to decay differently compared to a plenum vehicle.

 

how / Why do ITB's do that ??

 

Excellent write up.

Good to see how advance/retard on cam timing correlates in graphical form.

 

Often shorter than runners on a plenum & support much higher CFM, which can't be a bad thing at high rpm
