Denverspeed

It has been a while since I have made an entry in the old Denverspeed story book here. Since last time I posted, there have been some changes to the volvo. I finished up some modifications on an intake manifold to improve the high rpm breathing. I also installed a new wastegate to better control boost with the monster turbo I installed in the spring.

The intake manifold came out pretty good. I added some extra volume to the plenum area. Turbo engines like to have a nice big reservoir to hold pressurized air near the runner inlets. I also shortened the length of the runners and ported them. After porting and cleaning the inside, I welded it all back together again. Its installed back on the car now and working like a charm.

The new wastegate is a chinese copy of the venerable HKS 60mm wastegate. This sucker is HUGE! I had to do some tricky work on the header to make it fit. and there wasn’t much room under the hood to fit such a behemoth object. Here is how the header looks now with the new wastegate installed:

I am going to hold back info for now about how all this stuff is working on the car. I do have some prelimary results, but I want to wait to report them. I will say that nothing is broken, and the car seems fast. More to come later.
