Scat dry sump engine 2332cc allmotor plus nitrous (still sorting out) Only small valve heads 44x37 , 170hp at the wheels ( allmotor)





2387cc , cb comp heads , 218hp at the wheels

[BeetleBug]

Dakatak: I have to ask and please do not take it as a insult:

A 2.3 RACE engine producing 170hp. I take it for granted it is WHP and without nitrous? Thats 74hp pr litre. Even with the most "HP friendly calculators" it hard to get above 200hp at the flywheel. 

Take the Nash engine as a example as well, 2.7 with all the worst bits and bobs -  220 WHP.

Do you know what calculations you guys use when dyno testing your engines?

That is wheel power.
Pete's engine has never been dyno tuned.
but with the small port heads he has, there is probably less than 15 more wheel HP to find.
(170 was with NO nitrous at our dyno day 4 years ago.)

Michael Nash's car made a best of 228wheel,(226 with the smaller venturis),
and recently ran 10.47@132.75mph in a 1490lb car.
The extra air being naca ducted into the air box from the back and side windows at the track
has increased the power,( and it DID need more fuel than the dyno).

Most popular dynos in Australia are "Dyno Dynamics" and correct the number to a standardized set of weather numbers for comparisons.
My calculations show Peters to make about 190 FW hp and Michaels to make 256FW at the dyno,
 and 272FW at the track, based on his mph.

These engine power CALCULATIONS seem to match closely the figures seen on superfow engine dynos.

The formula I use asks you to divide the MPH by 234,
cube that answer,
and multiply the answer by the weight in pounds.

11% is a random number I use for wheel power, and seems to match everything that I have seen.

I think this is what a dyno must do and show the engine power . I have now one Bosch dyno on which i can work that is calibrated and it got a certificat that it shows the right numbers :-)

Dangerous, thank you for confirming that there is nothing "special" with your dynos down under. Most guys I have talked to use between 8 and 12% in their calculations from WHP to FHP.

A 44mm intake valve is certainly able to flow more than 187 FHP (170 + 17) and you do not need to search further than this section of The Lounge to find examples. As a extreme you can look at the "mouse" thread and the 1603ccm engine with a 43mm intake valve that produced 196 FHP on it's last dyno tests.

Personally I can not think of a more boring engine than a big stroker with a Engle cam, CB heads, 48 IDA's and the typical 150 - 170 hp and the excuse you always get is that they work or they are drivable or they last forever and of course the most popular excuse they are cheap If I built a dedicated RACE engine that produced anything less than 100hp per litre I would be very disappointed. As a matter of fact I would even call it a poorly built engine.

10.47 in such a light car is just a start and nothing special . That ET should improve based on the weight and your calculated HP and it's confirmed by the mph. It is one of my favourite race builds and it's a shame that it does not have a matching engine.

My favourite nitrous engine was recently sold (very cheap I might add) 2332ccm, 12.8 CR, CE heads by JPM, JPM raptor cam and EFI. It dyno'd 266 FHP on a very safe (read fat AF) without the nitrous and used a 135hp shot at the races. It was increased to 2386ccm and built to take a bigger shot of nitrous before it was sold.

Just my 2 cents.. Now heading to the garage. Sun is shining, it's around +8C and the last bits of snow is soon gone. Spring is here!

Someone was wanting internal pictures -- here they are for my current 2919 build

pauter crank and rods



Angle port heads 48x38



the siamese barrells in 101.6 (4")



cylinders and pistons



Heads finished and installed



Almost completed -- I have everything in the engine compartment including the innercooler -- should be ready to fire the thing this coming week -- if I get off my ass and quit posting chit on the internet lol

Didn't know Pauter made H-beam rods.

Right at 240 HP from 7600 to 8500 --- real nice power band -- real nice

[BeetleBug]

Nice, how big is it?

2386ccm, 10.7:1 CR, 245 FHP with muffler and belt @ 7250 rpms. But it does not belong on this section since it is a street engine running on ordinary pump gas.

Correct.
My old 2387 made 228 hp with JPM ported 044 heads and 44 mm intake (made 11.29 in full street trim). It could have made more power if I had tweaked it a bit more.
240 hp on a 44 mm intake isn't impossible even on pump gas.

Edit; oops! I just remembered that I installed 46 mm intake on them...

This is a real nice engine with real power,  as the et's show  . Not only dyno numbers :-)
Congrats ...

Thanks for sharing.

It confirms what Roman is saying above here with regards to a 44mm intake valve. 108hp pr litre, a proper race engine.

ET and mph is just about the most idiotic statement I can think of when it comes to the engine perfomance. The best engine in the world can not replace a poor car, a poor track or a poor driver.

The biggest difference between european and american's is that in the us every engine and car is built for rules . In europe we have no rules so everybody can do different stuff . I like more to race time slips than big hp numbers :-)

I know what you mean. My Super Street motor makes 597 HP on a famous Orange County dyno and cant get out of its own way. Must be me??? On the same dyno a buddy of mine made 963 HP with his 2442cc turbo motor using a raptor cam, a mac truck diesel turbo and cb performance super valve springs but can only runs mid elevens because the car is a piece of crap and the guys shifts like my grandma?

Sounds like a very nice dyno that shows some 100 hp too much :-)

I'd rather have a fast timeslip than a trumped up dyno sheet. I always hear about these crazy dyno numbers, but we don't race dynos. When your cars over there run faster than ours "on the same playing field" I'll give you guys props. I'm not going to get all jacked up over a dyno sheet. We run against guys making 30 h.p. more than us in Super Street, but there have only been two cars to run 9's. Both from the same shop, both off the same dyno.

Or maybe you would be happy if I put my motor in a piece of shit car and still ran good numbers?

Funny... We in Europe always hear about these crazy ET's but we have yet to see one car from over there managing the same ET or producing the claimed HP when it arrives Europe.

 

When you have the chance to race a lot you risk getting faster - logical enough isn't it? Until we get the same race schedule we will always be slower so until then the least we can do is to build proper engines. Which brings this thread back to topic again.

@ RUN IT: nice contribution.

Sounds like you guys might need to stop working on the engine's a little and learn how to set up a suspension or prep a track or go to driving school or maybe correct the Dyno?? Sorry but I'll take the time slip over a dyno sheet anyday. Never heard of a racing association giving credit for the most dyno HP. Added a little pic of another one of our incorrectly built engines just to keep with the topic.

That where us guys over here are going wrong we need to stop gluing all of the track and just do 7ft groove.

[kepajake]

It´s an engine and I´m gonna race with it, so I think it can be called race engine
Last summer it dynoed 211 hp / 262 nm. Now with bigger carbs and 1.5 rockers I´m hoping it will produce a little bit more.
