Can any one tell me what kind of gains they realized on a complete porting of the SuperRam base, and runners? Preferably on a 400+ cube engine?

Thanks. Tom

 

27 hp and 36 fl lbs at the wheels.

Which wheels? The front ones? Also, are you sure its not 28, and 37?

 

You will only pick up 40% of the gain through the front wheels.

 

I doubt that anyone has a good comparison for you. All I can tell you is that my ported SR pulled 340 RWHp in my 395 cu.in. stroker. see sig for more details.

I do not have a good before and after answer for you. I made multiple changes.

Thanks doc. I have an unported one on a 436. The base was modified to mate to the large ports of the Track 1 heads, but as far as the runners go, they are as cast. Just wondering if it would be worth the effort. Just trying to get every bit of power I can from my combo.

 

I recall John Lingenfelter telling me that a fully ported SuperRam was worth 20 HP. I never asked about torque or at what rpm.

Call LPE directly for some direct information.

20hp over unported? I though the SR only added 20hp or so over a Modified LTR. SO like 40+ over a modified LTR? ( I know it depends on combo) but that really sounds like alot, and no I'm not saying that it can't be true.

I was hoping to get some real numbers from a regular guy. Alot of times the large companies(not all of them) will tell you what you want to hear, just to sell their product. I would assume that the gains,(if any) would be more noticable on a large engine, over a 350, or 383.
