I am finishing a build in about a month or so. It will be a usdm gsr with a very good port job, over sized valves, fully built valve train, skunk2 pro 1 cams, on a stock block with a refresh and 12.0 compression pistons. On the outside of the engine will be a skunk2 pro manifold, and 70mm TB. Along with a big tube hytech header with a 2 1/2 inch outlet. My question is what anyone thinks this beast should do to the wheels on a good tune (aem). Im hearing no way more than 200 hundred on pump gas, and others say @ 220 or so. Dont know what to expect. Im gonna tear the bottom end apart now if im only gonna get 200. THANX ALOT

 

Should do the square root of pi to the wheels, if it's tuned properly of course.

 

Didn't you say you already are ~12:1 compression? Why tear the bottom end out?

 

it all depends on how well the motor is assembled and tuned, but if all goes well you should see somewhere between 210-220.

 

1.86 gigawatts.

 

If you have not built one of these motors before you might not want to over expect an output. While 200+ whp from a 1.8 B is a simple task for me and some others on this board its not very common at all. But hey i can make 200 whp from a 1.6 B http://www.intertune.tv

If you dont have a lot of hands on "B" building practice, which the highest possibility may exsist that you dont, it will take you some trial and error to get to your goals. most people finally realize that its not as easy as they thought and eventually give up or buy this part called a turbo.

There are so many factors on what a motor will make you cant really just list a few mods and expect a number to be predicted with any degree of accuracy.

If i had to bet money on it i would say under 200 on your first attempt. But i have no idea your level of knowledge.

here are some areas that generally if done somewhat right will increase power beyond stock.

-improved header design over factory
-modest compression increase
-larger cam profile
-larger exhaust sytem diameter
-improved intake manifold and air filter mechanism
-proper fuel and spark tuning
-cylinder head flow can be important but these heads flow exceptionally well stock so on the smaller motors (1.6-1.8) the gains are minimal at best on street motors.

 

yea, but if its not gonna be what im shooting for, im gonna have to go big bore or somthing

 

Thats about what i was thinking, ill be kool with that.
