Holy tiny V8 Batman!!

[jp455]

Hey all...I was lookinbg for some Formula SAE stuff and came by this. I had read about this car before (its Western Washington U.) but actually seeing a picture of their billet built from scratch V8 just amazed me.

Any of us have what it takes to make a billet V8 in a more "standard" size??

That is really cool. Any idea how much it weighs?

[homerneedspeed]

radical cars builds a v8 that is based on 2 gsx-r 1300 barrels and heads put togeather and quaife makes a mid mount north-south and a mid mount east-west transmissions for it.

Here's some vids of 1/8 scale blown running engines.

Well if you want a real Billet aluminum block contack CN Blocks.

I have seen one of these BBC blown on a dyno and it made over 2300hp on alcohol.

Here are some pics of a Billet Small Block Chevy

You know ive seen that before, and im still wondering how a tiny blown motor fits into a nice day at the vineyard??

Pardon me, do you have a tiny blown V8?

I was a participant at the FSAE event that had the WWU V8 engine. They used Honda 250 RR heads, was 550 cc and claimed 16000 RPM. It doesn't make sense though. Why spin an engine that has more internal friction (more piston perimeter and more bearing surface area) 4000 RPM higher than all the teams using 600 cc I4 engines. No doubt it was one of the best visually designed packages I've seen in 7 years of going to the FSAE event, but in the end the car never did more than spit and pop for a few seconds at a time. It didn't have an on board starter so was DQ'd as the rules state that you must have one. It was a shame it didn't run though, as I wanted to hear that puppy scream spinning that high and see how fast the car really was. Most of their other components were done in house as well, including bonded CNC uprights and the fully CNC'd tranny case and rear suspension. The car was set up with a fully stressed engine and tranny the same way an F1 or champ car is.

We watched them build up that thing on their website that year and anticipated seeing it at the competition. UMR was only a few pits down so we got a good shot of them trying to get that thing started. On their webpage it had sound bites and all kinds of stuff with it running. To bad they stole the sound bites from a real F1 car. It was a neat idea but they were way over their head and didn't have a clue what they were doing with that computer. They had it setup as two seperate engines but they were connected to a common crankshaft. Which made for a very ill running engine even when they did get it to fire up and idle for 10 or 15 seconds. Just goes to show you that haveing access to a 50 lb block of aluminum and a cnc mill doesn't make you an engine designer.

The transmission was pretty slick too, or well Transaxel. They took the stock bike transmission put it inline with the engine's crankshaft (normally in a bike its parrallel) and then machined their own ring and pinion. They fashoined a case for it out of two aluminum bulkheads and a carbon fiber skin. If they only put as much thought into the engine as they did the transmission they probably would have made it all work.

I didn't know they were trying to run it with 2 seperate controllers. That explains most of the problem right there. I've got experience with Electromotive, AEM, Motec, Muzzy and Chrysler's GPEC and NGC controllers (I work for Chrysler in engine design) and have never heard of anyone trying to take on such a lofty goal as making 2 controllers work as one.

[442olds]

They had the honda ignition controlers piggy backed. One per side each controler was hooked up to two coils. I think they thought the wasted spark and the flat crank were going to even out but something was way off. Then they had a single fuel controller, I think it was a haltech, which in my opinion is not the best thing to use to control fuel. A setup like that demands a much better controler like a motec in which they can also control the ignition at the same time.

The BMW V12 uses two six cylinder controllers running independantly. Sounds a little funky, but they both take crank position off the same trigger wheel, should sync. the two.

I think it's....adorable!

I'd like to drop it into a pedal car-bodied go kart for a jr. altered look...

I want one for my lawnmower!

[jp455]

I thought all flat plane crankshaft V8s were run as two separate inline fours?? At least thats what I always heard of engines like the Ferrari 355 and such, which is why they don't sound like the classic american V8...

They should have used an Electromotive Tec 3 (just coming out at that time) or a Motec unit. Both do fuel and spark, have individual cylinder trim, and you can specify the degrees between firing for things like an odd fire V6 or V10 (in this case it was an even fire V8 with a really wierd firing order), ie the Viper engine is an odd fire V10 where the firing is 90-54-90-54-90-54 etc degrees apart instead of 72-72-72 that an even fire (72 deg block instead of 90) or split pin crank (90 deg block w/ 18 deg offset crank pins) would be. Also, both controllers can go to 20k rpm on fuel and spark.
