since last year i've been working on a prototype I6 200 engine. i'm finally done. it has a custom made(by me) high flow head. i read endless books and ported and polished numerous heads to get the most power. I used the mill at my school to make it out of T2420 aluminum. the block has been bored, the crankshaft balanced, cammed, a twin stage turbo setup, and a 600cfm holley dominator carb. oh yes and the final touch. split fire spark plugs. in my auto shop class we've assembled it and put the specs in a dyno program and calculated 300+ horspower :shock: next wednesday were gonna take it to a dyno and basically blow it up. we're gonna see the maximum HP, torque and Rpm to the flywheel. don't freek out guys we have an identical one. wish us luck.
 
8) That's cool man. Hope it runs like you predict. Some of these guys may be asking you to make them one :twisted: Good luck with the dyno tests!
 
You mean get ready to take MY order, lol. Thats awesome man, wish I could make somethin other than a penut butter sandwich. Oh well, speaking of which....

its not impossible, students/faculty here at UMR designed and cast a couple prototype chevy 5-cylinder heads with the basic foundry we have in the MET department, its really kinda neat how they do it too, and imho, much better than machineing a whole head from a block.
 
"gonna basically blow it up" :evil: :evil: :evil: :evil: :evil:

Brainless destruction for the pure pleasure of watching it just pisses me off!!

No I don't go to demolition derby's or "tuff truck" events!
 
90Lariat, I wasn't trying to hint that it wasn't possible. I just wanted to make sure I understood what he said. There was another discussion I had on here a few weeks ago... I was suggesting something similar.

Sn0wy15, could we see pics?

It is only brainless if data is not retrieved. If data is retrieved, it is Destructive Testing.
 
THATS TOPS!!!

good work mate.

can i make a sugestion..?

y not try and make a cross flow hemi type alloy double over head cam cylinder head for the older model ford i6?

full hemispherical chambers with oposing big ford 5.0lt valves (2.02 intake 1.89 exhaust).

use retainers/springs from the ford 5.0lt motors as well.

have the cam strike cam fingers with lifters in them (pretty much like the ford romeo v8 engines- dohc 4.6lt mustang v8).

it would be the ducks nuts!!!.

one man here in australia has done similar but using toyota shim style (from a corolla) valve train in there. early testing has seen on a 202 holden motor (essentially same as 200 ford i6) makes 325hp n/a carbie fed stocko with just the head.

cheers.joe.
 
Were you planning on blowing it up before graduation?

If so, you should have started out with a chevy. :) :)

(It has been a month, now... :roll: )

I envy you the opportunity! I haven't been able to run an engine to destruction on a dyno since 1969 - a Chev 305 from an El Camino. Boy, did we ever learn a LOT from that one test! It also became valuable info for my bike racing days, years later, and even until today, because of the things we learned about bearings and oil.

That's not to say I haven't destroyed other engines. :oops: -Just not on a dyno or on purpose!

Other than valve float, though, it may be tough to destroy a 200 I6!
 
Perhaps you guys don't understand thepoint of a dyno. I've run many engines on my old dyno and now at the one in the new shop.
An engine will reach it's peak hp and tq at a certain rpm, after that it noses over and your just being stupid. I've seen engine scattered on the floor by mistake, and it's a hell of a mess to clean up!! If an engine peaks at 5000rpm, there is no point to take it to 6000 or more because the hp is dropping quickly. And if you just "cam it up" so it will rev higher, the heads etc will give out or run out of flow in most cases. OR, you put big flowing heads and monster cam in a stock short block and spin it to the moon to "blow it up" in which case in my opinion your an idiot and your wasting time and $$$! You can use mathematical equations to figure max stress levels on rotating assemblies if you want, why blow up an engine...besides the brainless factor?
I saw a video clip of a jap crap car that a guy wound out on a chassis dyno, the engine peaked around 6500 or so, he took it to almost 8000 where it went boom...what the f$%^ was he thinking? what did he think he would accomplish? THIS is what I call brainless destruction!
Ever watch burnout contests? Some stupid moron hold the car to the floor and either blows the motor or the tranny etc, and the people aren't cheering FOR him, they're hoping something breaks!!! Common fricken sense would say to keep it around 3000 and watch engine and tranny temps. But no, there are morons who think rpm will win, and then are surprised when something breaks.
Yes this REALLY pisses me off, and I'll again call it brainless destruction for mindless pleasure. :evil:

PS, one dyno mule I built has over 2300 pulls on it when I freshened it up! (22% blowdown) :oops:
