We have forged 11:1 DOHC pistons, forged rods, p&p SOHC head, crane #12 cam, ported intake manifold, larger TB, header, test pipe, performance computer, and an upgraded clutch. Also, we installed the 3.94 tranny. What my buddy wants to know is, how much power he might be able to produce and if this is a pretty good setup? Also, I estimated that his compression will go up to around 12:1 with that combo. If anyone knows what the exact compression would be, it would be greatly appreciated. Oh yea, I will post a video when we get it started!

Dude, that's an ausome setup! I guess you'll at least make 300HP. LOL!!! But anyway, maby 12.2:1 compression, you might have to run race fuel?

that is a pretty small cam for that much compression. what kind of vehicle is this going in. hopefully a race car, cause you are going to need a lot of octane to keep it from pinging itself to death.

i know i'm new to this whole thing but if you put the time and money into sometihng like that it could be great better then just a look a like car i wish you the best man. p.s. i have seen the egle rods and the high con pistin and i am the one how help blue print and blance the hole thing. ricks this and that shop. i'm not trying to be mean but it took me 5 hr to finish the whole thing

Hey, noob. AKA Shake N' Bake. I have know idea what the hell you just said, but someone needs to go back to grammer school!!!

If you are going to say that someone should go back to grammer school, you should use the right word for what you are trying to say.

I have no idea what he said either. Shake N' Bake, please repost what you put, but put it so that we can understand what you are saying please.

LOL, my bad. I feel like a tard now.

thanks for that man. the pistons that he has are from modern performance. and he has eagle rods and everthing was blue printed and balanced and i put everything together for him. and when you post your pics it's going to be a orange block with 1.2.3.4. on the pistons and if i'm wrong my bad but whatever. is that good enough for you buddy!

gotchya now

but what kind of a car is this going into, a race car or a street car?

im sure the parts are good, but even if all the parts are the best money can buy, if you dont run the right gas it will still ping itself to death. i guess since you are assembling engines you probably know that already. i guess this is mainly curiosity for me, because that is a lot of compression and not a lot of cam.

detonation > than any piston

Hey can you post your information on the BBP i just kind of like to see what all you've got according to that because then we could tell you for sure if it would be a good setup. With that we could also get you closer to finding out what kind of compression your running. With you being the one building it your self you sould be able to post that in no time.

i'm still new to the lingo what exactly is bbp and this is going in to a street car the cam that i put in there is massive cumpared to the stock one

i'm a tard i'm at home i'll get it in the moring. from th shop

yes compared to a stock one it is big, but a lot of the others i see with that much of a c/r are using a minimum of a crane 16 with a lot of crane 18s in the mix to bleed off some of that compression.

I'd say by the stuff you have done maybe 11.5 if your lucky its stock dohc pistons basically(forged) i know before im corrected and pp head and dont they generally have around 9.2 to 9.8 if they are lucky and a pp sohc head which has the smaller combustion chamber which equals higher compression but only by a point in most cases so im not sayin anything bad and dont take it that way. ( i saw what happend a few post ago..lol) but im gonna say maybe if your lucky 11.5

Balance and Blue Printing

Well if you haven't guessed by now, its me and Shake N' Bake doing the project. But it is his car, so he is worried now that he might have to run race gas, because everyone in town is telling him he doesn't. Also, how big does a crane cam go to on a SOHC. Being very self concious, he wants me to ask if anyone will throw him a guesstimate on some HP #'s. Please help, if you at least toss him some bullshit #'s he'll leave me alone!!!

i forgot to say that the first gen dohc engines are going with those cams, ive even seen some with 20s, 22, and bigger.

according to modern the biggest sohc crane is the crane 14. looking at comparisons of a sohc crane 14 and a dohc crane 18 they are about the same as far as engine requirements and where the power band will be.

yeah, i kind of guessed you two were together after looking at your locations.

So going with the #12 camshaft selection is gonna be allright with the SOHC cyclinder head and the DOHC bottom end?

i would say you are closer to what i originally thought, but i would still think you would want the crane 14. but i am not a cam expert.

one thing you can do is call up crane cams tomorrow and give them all of your engine specs and ask them to help you pick a cam. then go with that cam. they will need to know EVERYTHING. my dad has been doing that for years, and i dont think he ever got a bad rec.

thanks for your help how much whp. do you think it will be pushing i'm hope alot give me and idle

170 to 180 HP is my guess. Are you happy?

your a dirty little man. mister i have a turbo neon i'm so fast one day i will bet you but untell that day comes i'll just deal with it lol see ya tomorrow bye dud

Isn't it past your bed time dude. Your bed time is 11p.m. You've been on here for 5hrs now and you'r allready addicted. What a 2GN whore!

At this whole thread.....



But, to address what seem to be the two main questions. You're not going to make more than 150 WHP on that setup. Especially not with a tiny cam like the 12. If you want 180 hp, you'll need a Crane custom grind cam bigger than the 14. And you'll need a way to tune fuel. With a performance computer, I assume you have an AF/x, you will have a very hard time getting it to run without pinging on anything less than 93 octane...even then, 93 might not be enough. The AF/x deadens the knock sensor, and advanced timing...to what extent I'm not sure, but just be careful.


Bottom line...that setup, without knowing any more about it = 150whp.

and guys, if you are going to take the time to make a post, make it so people can read it, i mean honestly go back and read the posts you have made shake n bake.. take your time and read it over before you post it.

anywhos, can't wait to see pics of the finished product.

what i think is crazy is the fact that some of you are giveing me good anwsers and the rest are talking alot of shit ok your car looks good but when a kide on a bike can bet you looking good doesn't help now does is it so unless you have something good to add then don't say anything .p.s. thanks for the info keep it coming

ummm...i don't mean to be hard on you, but your GRAMMAR is quite possibly the worst i've ever seen. i think i see 5 separate sentences in the above post. i'm not even sure it makes sense if it wasn't one run-on sentence.

regardless, you have too much compression and the wrong cam. your dynamic compression is going to be out the roof with >12:1 static compression and the cam you've chosen. race gas won't even help with the scenario that you've proposed. you are going to want lots of duration and overlap to compensate for the crazy compression. my guess is you'll need a custom cam with reduced base circle and lash caps to be able to run on anything near pump gas. good luck.
