Arif Posted September 24, 2011 Share Posted September 24, 2011 (edited) I went to the local car show tonight and saw this strange looking Volvo with a HUGE turbo sitting on top of the engine. So I park next to him and check out his set up. Here are the details: Volvo 2.4L engine with 11:1 compression, Vovlo/Holstet truck turbo, custom exhaust manifold and dual wastegates. He's running 100% ethanol on this thing. The reason for the dual wastegates is because he's separated the exhaust gases from cylinders 1 and 4 from 2 and 3. This way the turbo sees exhaust gasses in synch rather than all 4 cylinders. According to the owner (who used to work at Bell Engineering aka Corky Bell's shop) another benefit is turbo lag is greatly reduced despite the size of the turbo on a rather small engine. Enjoy the pics: Edited September 24, 2011 by Arif Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted September 24, 2011 Share Posted September 24, 2011 Neat! Wonder where he found out about this dual wastegate setup on a 4 cylinder?! Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted September 24, 2011 Share Posted September 24, 2011 Which meet where? Quote Link to comment Share on other sites More sharing options...
Arif Posted September 24, 2011 Author Share Posted September 24, 2011 This was in San Antonio at a burger joint called Biff Buzbys. I had never seen a set up like his before. I asked him if he can put a big turbo on a 2.4 then you should be able to run a T4 turbo on a 2.8 and it should be as responsive as a T3/T4 turbo and see higher boost levels at lower rpms.

Sparky Posted September 24, 2011 Share Posted September 24, 2011 Dang, is that meet worth going to? I used to drive up from downtown but was continually disappointed by row after row of c5/c6 vettes. I'd like to meet this guy as I'm building a 2.4 Volvo engine for my dads 1800 and I'd be curious what parts he's used. Quote Link to comment Share on other sites More sharing options...
Arif Posted September 24, 2011 Author Share Posted September 24, 2011 There's still a crap load of corvettes but every now and then you get something interesting show up like this guy's car. I learned a ton just talking with him for 30 minutes. I'll ask him if I see him again what forums he hangs out in. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted September 26, 2011 Share Posted September 26, 2011 There's a guy local that's running a big turbo at 16psi on a stock 10:1 NA volvo engine on E85! It's a total sleeper too. Quote Link to comment Share on other sites More sharing options...
260DET Posted September 28, 2011 Share Posted September 28, 2011 Divided housing turbo's are not uncommon eg VG30ET, although most have a single wastegate. It is a good idea and does work well. Quote Link to comment Share on other sites More sharing options...
