thatcarguy350 Posted September 20, 2007 Share Posted September 20, 2007 What?!? I guess this one got a bit wet and needed to be hung out to dry... It's beautiful! Quote Link to comment Share on other sites More sharing options...
supraspaz Posted September 20, 2007 Share Posted September 20, 2007 I may have missed it being discussed. But about the Flat-plane SBC, what sort of cams would need to be created? or is that even a big issue for a cam maker to create? i think the dimensions BRAAP listed could work, but I am curious about the rest of the compnents to make it run.

supraspaz Posted September 27, 2007 Share Posted September 27, 2007 Cams for a vh45DE flatplane crank arent even going to be an issue for me. Well I started shopping around for a company that woudl make me a flat plane crank for the VH45DE and Scat didnt get back to me but Crower did. Crower told me that they WOULD NOT make me a flat-plane crank. That they had tried in the past and the resulting motor shook too much. So if the pros wont do it for any price i suppose there isnt many more options for myself on making an engine with a flat plane crank. Please chime in if you have any other options!

Clifton Posted September 27, 2007 Share Posted September 27, 2007 I know you could find someone at SEMA that would to it. Quote Link to comment Share on other sites More sharing options...
datsun40146 Posted September 27, 2007 Share Posted September 27, 2007 Well, Ferrari makes flat plane cranks all the time; what then is Cower doing wrong? Did they not balance the crank after machining or where they lying to you? Of all the crank manufactures I would’ve thought scat would have jumped on this chance but I guess it wasn't to be. Hey BRAAP didn't you say you could turn a standard SBC crank on a lathe and create a flat plane? Would it have the same balance issues the VH45DE did?

supraspaz Posted September 28, 2007 Share Posted September 28, 2007 I know Ferrari has flat plane cranks, thats why i dont understand why its almost like black magic to have one made for a motor. I might try contacting Scat again. I really think this is a fun idea if i can find a company with experience and drive to make it happen. Crower didnt say that they had tried a VH45de flat plane, they just said that the motors they did try shook way too much. Clifton, you have any links to companies that were at SEMA that might be interested? I am wore out from searching the web for a while. Who wants to find the secrets of the Ferrari engine enternals, theirs dont seem to shake too much.. why? Quote Link to comment Share on other sites More sharing options...
capt_furious Posted September 28, 2007 Share Posted September 28, 2007 12 cylinder engines have a tendency to be pretty smooth, no matter what the configuration. Quote Link to comment Share on other sites More sharing options...
ZROSSA Posted September 28, 2007 Share Posted September 28, 2007 We were talking about the v8 ferrari's. Lotus and TVR also made flat plane v8s. The v8's in indy racing are all flat plane as are the ones use for the DTM. So you should have cranks floating around that will fit the nissan, nortstar, audi, and merc engines with a displacement at 4.0 lts. I think Opel used the northstar/chev/olds engine in dtm.

supraspaz Posted September 29, 2007 Share Posted September 29, 2007 Zrossa thanks, I will try looking around at race forums for old parts. But really, as you have said, many cars use flat plane cranks. It cant be all impossible to get one to work in an SBC or a nissan v8. What is the trick to making them manageable for street cars like ferrari, lotus or tvr? Quote Link to comment Share on other sites More sharing options...
Chaparral2f Posted September 29, 2007 Share Posted September 29, 2007 For the money you guys are talking about, if you want a small high revving engine maybe you should look into finding a used Foyt Coyote They only weighted about 400lb, 255cid, and made about 750hp with prob about 40 (I'm guessing) lb of boost. Of course that is a 30 year old engine:) Sorry, but I've always been a sucker for that engine. Quote Link to comment Share on other sites More sharing options...
HundredPerCent Posted October 19, 2007 Share Posted October 19, 2007 if you want somthing exotic why don´t you put a audi S2 or RS2 engin in it! its 2.2l 5 zylinder turbo it has a verry uniq sound ! the VW GOLF 4 in this video is tuned by dahlback he use also audi rs2 engine listen that sound! http://www.youtube.com/watch?v=aD6yREzC_6M Quote Link to comment Share on other sites More sharing options...

Guest griff30 Posted October 22, 2007 Share Posted October 22, 2007 braaapp, hit the nail guys. I am or was, or what ever, a Navy jet mechanic in my past. (Now an R.N. , but thats another story and Im too drunk to type it) I studied IC engines of all tyes and would say Braaaaap Was on ke ywhen he mentioned the 180 headers. Smokey Yunick of Engineering Hall Of fame had used flat cracks in SBC and had some at the warehouse. He also used 180 degree headers. He liked the sound, but hell Im too drunk right now to remember much from his book let alone edit my post for grammer. Anyway, it sounded nice with either and he wanted to research it more. A BBC 454 Chevele can sound like a flat crank Ferrari wth 180 degree exhaust headers and keep the 44% improvement in sootheness do to regular crank. At least I think it was 44%?

KillerBjt Posted December 2, 2007 Share Posted December 2, 2007 I would like to revive this thread and mention a new point. Audi has the RS4 which is a 4.2L v8 that revs to 8250rpm, now this is a accomplishment especially when i went to go look up the specs and it has a bore X stroke of 84.6mm X 92.7mm and a compression ratio of 12.5 to 1. Those are pretty close or the same as the other 4.2L from the the other Audi's, so i think we could easily mod some of these to spin really high with slight mods, some years even came with 5v per cylinder! The only issue with these engines is the transmission, im currently in the planning stages of trying to throw one of these V8's into my 240z with the 4wd. I might be contacting you Braaap in the future for some info and to acquire some of your services. Quote Link to comment Share on other sites More sharing options...

Google didn't get me anywhere Quote Link to comment Share on other sites More sharing options...
KillerBjt Posted December 3, 2007 Share Posted December 3, 2007 As far as i know, there is no RWD transmission for the Audi V8 but you might be able to remove the front drive shaft and just run it like that. Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted December 3, 2007 Share Posted December 3, 2007 I think Audi even advertises every model uses their quatro system. Can you just use the stock one and gut the transfer case? Pretty sure you can. I like that motor. Its a shame the power to ratio ratio is so high lol. Quote Link to comment Share on other sites More sharing options...
