Not to mention smaller engines are capable of more horsepower per liter. Theres some scientific way of explaining why a smaller engine is capable of making more power for its size, but I forget why exactly.

 

DriveFast7, your sig is TOO HUUUGE.

Here is a revised, and trimmed down version for you,
just use the address on the picture.

I could be wrong but

his engine is carberated and has a distributor????

WTF

slide throttle injection and direct fire could easily net anouther 50-75 HP

 

You mean for a rotary engine? or for a piston engine? Do you mean larger displacement or more rotors/pistons?

I'm askin this cuz i'm curious about this

 

20B PP = 13G engine

 

I mean for displacement, its not rotary or piston engine specific. I saw it on some TV program about tiny engines, they explained why, but i forgot, haha. If you take a look at so many engines available today, you see this is true. Look at motorcycle engines, honda engines, small block V8s, then big block V8s. On average, progressively smaller horsepower per liter. I think its due to smaller engines having progressively higher rev capability, as the torque numbers are more constant for each displacement. You see 1000cc motorcycle engines with 150hp NA from the factory, then you see an 8.0L Viper engine with 450hp or whatever. Even the best of the best, Ferrari, gets 660hp out of a 6L V12 pushing current technology to the limit. Of course larger engines are capable of more overall power, but the smaller an engine is the more power it can make for its size.

 

Yep, I know. I tried all evening to upload a smaller pic but rx7club kept stalling out and 404 error. This webpage is real darn slow at peak time.

How does this sig look?

 

There are a bunch on eBay for sale right now....

 

Ya but i think the one he runs is actually a rare pantera model that is either a 43 or a 46 ida 3c. I have only ever seen one on ebay. the rest are all about 3mm smaller. im sure he has his somehow boared out too, because that is kinda small for a pp. most every one likes to run the 51's.

Lazarus!! Those are most likely PMO carbs made for Porsche's...they're usually 50mm...and cost BIG BUCKS!
