We only did some preliminary tuning (over the phone, telling shiv numbers from the datalog so there is definitely some more hp in there), but the upgraded turbos picked up peak about 30-35awhp, and ~55awtq. They're making around 45-50awhp more than the stock turbos at around 5500rpms -> redline.

hope you change your mind, not trying to convert you to a drag racer or beat up your car at the track.. but 1/4 mi times would be a great indicator of performance results for these upgrades, got to try it at least once..

In most parts of the world it takes more to "race" than a straight line

Don't get your hopes up for a trip to the strip as it most likely won't happen.

also, in terms of videos.. I plan on taking a bunch but I'm still waiting on the powder coating place to finish up my summer wheels. I really can't do any high speed testing until then

was going to order my set as well but some vendors (helix) are saying that they'll only accept turbos with ZERO shaft play for this and the ones on ebay, all have some to minimal shaft play...which vendor are you thinking of going with, TiAL?

is Helix replacing the shaft as well or just the compressor+clipping the turbine? if it's the latter, it might be why they have that requirement..

if helix is asking for no-shaft-play turbos it sounds like they're doing an upgrade like TiAL. but I could be wrong

I lost traction all through 2nd gear the other day with 2 people in the car on my snow tires

to say this car makes a ridiculous amount of torque on pump gas is an understatement
