Any low compression TT guys on here?

anyone with a 9.5:1 compression with hellion TT on here?

Looking to see how you guys are going when cruising around town are you getting massive lag until you go WOT?

Looking to increase boost, well get some boost at lighter engine loads.

At fixed rpm:
You need more energy turbine side
Or less energy(work) expended compressor side.

Or cruise around at 6k rpm all the time.

Wiper fluid pumps + Wrap copper or stainless line around exhaust after turbo, inject before turbo in collector?

Chumpcar/Lemons grade Spooler: injector redriver. Copy signal from one injector and “or” it together to get at least one injector firing extra. So an injector fires once when its supposed to and again extra. Preferably timed to coincide with valve overlap/blowthru to get excess fuel air in exhaust on initial WOT.
Ie. Cylinder 1 redrives 3 on a 2000 A4 2.0T. Not sure on 5.0 timing... ask your tuner?
Gated by WOT and RPM settings.

Changing the a/r on the turbos is the way to do this, as well as the size. The smaller they are and the lower the a/r the faster they will spool but the more top end you'll lose.

This is just something you'll have to deal with if you want a ton of power on turbos.

Borg warner has been working on something cool in this regard, they have been developing "ebooster" turbos which have an electric motor and a microprocessor in an all electric turbo which flows helps spool your real turbo when placed upstream or downstream of it.

They also have variable geometry turbos which can change the a/r mechancially, as well as multi stage turbos. Cool concepts, maybe in a few years tuners will be able to capitalize on this technology.

drop the turbine size or AR on the drivers side only?

BMW played with some eletric assisted turbos a few years back. They never really caught on as BMW just sized their turbos better.

I think most people over size their turbos. I understand the thought process but undersized turbo can make for faster car in a lot of cases. Especially on manual cars.

In theory you want to run your turbo at 100% at peak power.
