What are your guys thoughts on the 2j racing turbo kit? It seems pretty legit, has lots of parts. Would this be a good option?
Which ones have you found to be water to air ic?They made it compact and economical. Its an interesting setup for sure for those purposes.
In fact I find that alot of modern day turbo charged production cars and suv's are watercooled. But for street use, air to air 100%
This exactly. Alot of European cars and I think even some of the bi-turbo systems are water cooled with seperate intercoolers. Its a complicated mess under there but has its perks for our cars, especially for drag racing as stated.So, I helped develop the intercooler system for this kit when I was working at 2j for a few months designing parts for him. The intercooler is fine so long as your not doing circuit racing, or if you plan on running over 300 at the wheels. It starts to heat soak after that unless you run a waaay bigger heat exchanger to keep the temp of the water way down. Another thing you can do is run an additive to help with the thermal efficiency of the water. But 10/10 easy to install.
As for what cars today are water to air: most BMW SUV's with a turbo. Any TT lambo/r8 is water to air. The new wrangler with 2.0t is water to air. Any oem roots supercharged car is water to air (shelby gt500, demon, hellcat, ect.). Q50/60 is water to air.
Water to air tech has really improved over the past 15 years. a lot of aftermarket turbo kits are now coming with them.
When I do drag builds in my shop I do water to air. Its more components for sure, but the benefits way outweigh the complexity. With ice and a big reservoir tank, you can easily get intake air temps to start BELOW ambient air temp.
