VTT 2+, Port Injection Build - Dyno Progress

[V8Bait]

What changes are you making to the vanos in those areas to achieve that superior efficiency performance becuz racecar?

*fixed so I could answer without offending the ghosts in the thread*

Close the exhaust cam earlier (trap some exhaust) and/or close the intake cam earlier (prevent full cylinder fill), but only at lowish loads. Reduces pumping loss a lot, holds on to more exhaust gasses which lowers the effective displacement of the engine, and maybe lowers emissions some. Watch your overlap so play with which cam changes work best, it's not the same for st cars and oem.


Now that all the hippy shinanigans is cleared up, great work on the car Ghost that powerband is great!

How did you get that fitting in the front intake? Also, can you show more pics of the rear pipe and maybe label it, trying o replicate this. Thanks for your help and awesome job!

I ordered that fitting online. It is called something like silicone hose nipple adapter.

I built all of this and showed dyno gains before there were inlets available. Given the many varieties available now, your best bet is to buy a set. The VTT worked very well for me.

I really like the look of this and the fact that you do not have to relocate the components. Do you use a VTT rear silicone hose now? Do they sell them individually?

A lot has changed since then.

I broke the stock frame HP record using the VTT rear inlet here: http://www.boostaddict.com/showthrea...rame-Turbo-WR)

I switced to a VM single turbo kit here: http://www.bimmerboost.com/showthrea...Dyno-Progress)

The VTT products worked quite well I'd say!
