O.K. I have a street / Pro Mod car i'm building my question is about building a small motor so i can keep it lite at around 1600 lbs. and make enough power to run Pro Mod with it.
Then I can have a Big Motor to run the unlimited street class @1700 pounds.
i know what it takes for a big motor the question is for the small one.
Could 2000 cc make 500 hp?
how about a 1914?

I would be curious to find out the limits of a small turbo engine. The 1915 turbo build up in Hot Vw's put out 360 hp and split the cylinder doing it, maybe a few more upgrades and some NOS?

 

[Jeff Newcomb]

I would think you could. All you big PM guys are makin well over 4hp a cube so at 117c.i. x 4 your getting close to 500hp(468). Seems like a reachable goal to me!! ;D

The 2 erics are prob over 5hp a cube. That would be 585 at 1915cc's.........

 

[Jerry Matsko]

Thanks Newk,and Lanky.
I know Kawell's was making 360 on the flywheel dyno and the motor in Richards Ghia was making 340 to the ground which would be somewhere around 410 or so at the flywheel right ?
Richards was carb draw thru and 28 lbs of boost.
my thinking is with a DFI unit on methonal i should see about a 20% increase in power and about 40% in torque at the same as Richards as the baseline should be 410 or so at the ground if all is relative.
then throw in a nice intercooler which could be good for up to 30% more in power wouldn't that take it up over 500hp. and if i can come in at 1600 lbs the class minimum this car should rock the eights? Maybe?
or should i just build the big motor and add 500 lbs to it.
just thinking out loud.

Keep us posted on the progress, I love hearing about small engine's making big hp! I want to build a small displacement turbo motor for my daily driver.

 

[ErikTheRed]

I have always been a big fan of smaller motors making big horsepower, just seems way more impressive. I'm also a fan of odd displacement combos, such as my 2221cc (80x94).

Make 500+ ponies with a 1915 and kick all their asses. ;D

 

[Jerry Matsko]

I would love to see this combo work but i have to get the car done too.

 

[MagOO]

All things equal( i.e. cfm to performance goal ratio proper valve lift, timing and durration etc etc etc , a smaller displacement engine will ALLWAYS make MORE hp per given displacement if a 2275 can make 600 an equally endowed 1915 should be good for 522 -527 ...A well scienced short stroke package with a big piston for valve area should kill with close to 550 hp...84 percent in size but 90 percent of the grunt .. and less parts breakage...try it!

 

[RED BARON]

easily 8)

 

[Hotrodvw]

Let's see what I can squeeze ou to fmy 1641.

 

[Dean N]

what do you need to get it done jerry.... besides time haha.

 

[Jerry Matsko]

Besides time of course money and i need to finish all the chassis work and body work and paint so maybe by spring Bug-o

 

[bewitched]

On another forum there is this swedish guy who made 190hp out of a 1603 engine 8)

 

[bewitched]

Check what those guys ran back then,1700cc in the 13's,1776 etc 8)

 

[Jake Raby]

The engine has made a best of 186 HP on my dyno, using 51.5mm IDAs at 8,500 RPM.
It's used for Land Speed Racing

Here are a list of the records it has broken.

I just finished twin plugging this one and we are hunting for another record, in a new class this October. I LOVE to build super revving, small displacement beasts...
Two weeks ago I finished a Porsche 356 engine used in the same class, it made 165 HP at 9,000 RPM with a 58mm destroke and a large bore.

 

[bewitched]

Damn,why build a 2332 then,lol :agree:

 

[Jake Raby]

But all that HP makes no torque... The 356 engine I built only made 100 lb/ft of torque at peak.. Luckily TQ isn't necessary for LSR.

 

[Jerry Matsko]

we have made 350 hp and 325 ftlbs of torque with a 1915 so far to the wheels.

 

[Hotrodvw]

WOW!

 

[Dominick Luppino]

I went [email protected] 137mph with a 1835cc, 1725lb. The car set the NHRA SS/DX record back in 1990
