looking to build a 200hp autocross engine, I have done the searches but not many direct answers.

I am staying away from turbo and efi want to keep it simple. My thoughts were BP and 48 IDA. Good idea or bad idea?

 

What car and what class?

 

914 probably XP

 

I wouldn't think that you need to go as far as a BP - a good street port maybe. I know that the club racing folks are getting up to 175 rwhp out of an S5 NA motor with stock ports and internals.

Good luck,

A good street port and 48IDA should net you 200 rwhp. This is assuming 3" exhaust and good ignition, properly jetted carb etc.

 

thanks for the replys' fella's yeah I think a good SP would be better for my application

 

what do you consider good ignition

 

dumb question I guess

 

Unless it is stretched to the limit, a streetport and IDA isn't usually going to make 200 hp. Top National EP cars are making that, and even a bit more, but most big streeetports are making more like 170, maybe 180 without some serious dyno work and optimization.

 

I have an MSD 6al on my E Prod 2nd gen. It is a fully prepped National level car.

 

where are you located at?

I can live with 170-180 my car is going to weigh between 1600 and 1650....

I am using a SP'ed turbo II with na rotars and a Holley 650 2barrel
