(02-07-2019, 10:58 PM)wiseman89 Hi everyone,

I havent been updating my project thread but my om606 build is slowly coming along. F-tune rods, f-tune valve springs, 8mm myna pump, 722.626 trans with a modified high stall converter, holley fuel pump, is some of the items the motor will be running

I have a nonwastegated manifold being made and Im looking for turbo advice.

My goal is to have a 500whp car. When I look at someone like dieselpumpuk's videos, im seeing how hes hitting 400bhp with turbos like the hx40 or s200. Then a s300 turbo hitting 600whp.

Is there a turbo combo that will hit the middle of the road 500whp that will lag alot ?

Also since I have a nonwastegated manifold, should I get a wastedgated turbo ?

Thanks

The only dyno numbers you can trust, in an absolute sense, are engine dyno numbers. All these chassis dyno numbers employ so many correction factors and assumptions that people can pretty much claim whatever they want in terms of hp. The exception would be where a car is tested and then the motor is modified and then it is tested again on the same dyno with the same settings. Then you can get a trend, but it still depends upon ambient temp and humidity on the two test days being similar, etc.

The higher your HP goal, the more lag you will have in a single turbo setup. It is pretty much that simple. You can get high HP burning very rich AFR with a lot of smoke and downsize the turbo a bit. But that is pretty crude.

As far as I can tell, erx000 setup with edc pump, a vnt small turbo and an hx50-frame large turbo with two 60mm bypass gates and a Baldur and/or olefejer controller is the way to go for driveability and high max power. Otherwise you are trading driveability for max power. Designing for intended use of the car, rather than an arbitrary hp number, is important to your eventual satisfaction level. If you need 6000rpm to get the 500hp, perhaps you should ask yourself how much time you plan to spend at 6000 rpm, and how much smoke you want to make while you are there (or at any point on the journey to 6000, really).

Cool project. Post some pics!
