That car will be amazing when finished - as well as having that much power, so much weight has been lost from the bodywork!. Well done

[landspeed]

Holy repost! Read above mate....2.1 bar and race fuel.

The reason for it needing 2.1 bar rather than 4 bar is probably because internal combustion engine efficiency increases to nearly 40% at higher load, compared to 22% when driving normally. Therefore you need less air / fuel burnt to get the same BHP. Although the fuel efficiency decreases on boost (due to enrichment), the power output 'efficiency' doesn't.

Roger_Sausage - I Reposted by mistake, and fixed it - sorry for that.
landspeed - Either I dont understand what you say, our your wrong.
Take a look at my previous post on this thread.

great project
Nice too see you back tone

[SM]

Race fuel is around 116 Octane, and therefore you can dial in a lot more advance = more power at lower boost.

boost is not what you need to measure to calculate engine power, but flow, flow depends on boost and restrictions. Hence why a small turbo @ 1 bar produces less power than a large turbo @ 1 bar as its all about flow. Flow depends on cams, manifolds - well, lots of things.

yay BigTones back
is that going to be the finished colour? Its a proper Stealth look

[AdamB]

Can`t fault the colour sceme if it does stay like that!!

[spesh]

i'm gonna pick bits off your bumper when its finish. so nerrr.

[bigtone]

sorry lads Im going to have to come clean about the colour.....

thats just the primer

[Pablo13]

Wow cant get over how clean this thread is compared to you old one! Lookin good Try keep it that way, mayb try to actually have at least one picture on each page this time to keep everyone interested

[SM]

thats just the primer

I guessed that

[Fake Ben Taylor]

I guessed that

me too

[Yakko]

Wow. Such an awesome project, definatley the most inspirational on the forum. Your attention to detail is stunning.

Thanks for the update.

SM, i dont whant to hijack the tread from its main topic.
Just on thing though - Aturbo doesnt produece power. A turbo simply supports the power made by the engine. An engine with a small turbo @ 1 bar, will make less power then with a bigger turbo @ 1 bar, because the increassed back pressure that the smaller tubo will create.
Allso, you can only advance the timing by so mutch, and the advnced timing will not create as much power as compared to increasing the boost.
I still find hard to understand how 640HP are achived at 2.1 BARS on a 1809L engine at 7800 RPM.

[Buffy]

Buffy you'r right, i ment almost 3 BAR, and not 4.
But still, how did you guys manage that ?
Racing Fuel or Not, is only to prevent detonation, but the engine still needs to be able to inhale enough air for 633HP, reguardless of the fuel you use - Unless you use Jet Fuel wich in it self produces more energy, or this RACE fuel is not just OCTANE BOOSTED....

The "Race Fuel" we have here in Israel, is just a higher octane fuel, so iam guessing what you use is something else then? Can you explain to me what it is exactly ?
I guess i mix up my terminology of the things.

As i know, for an engine of 1809cc to produece 633HP , it needs to inhale about 928.89, wich at 7800 RPM means that it has to boost 43 PSI's for that....

So....???

Although Tony has given you the basic spec of the engine some secrets still remain (no nitrous before anybody asks) Norris Designs built the
engine and as far as I'm aware it's their most powerfull CA to date. Try asking Simon at ND if he'll tell you every aspect of this engine given the amount of money he has invested trying various specs to get this far

[The Big Yin]

holleeeee mother funking shit


4 pages of posts solely about the project impresive, how long has this taken so far?

[Messydan]

probably not as long as its taken me to read it LoL.

Well done guys but MORE PICTURES PLZ!!!

Has to inhale about 928.89 what? Cubic feet a minute? That would be based on various assumptions including about the brake specific fuel consumption of the engine and so on and so forth. Perhaps the assumptions you are making are not accurate?

The CFM is accurate, but he hasn't corrected for density, temp, and a number of other factors that you must rate along with CFM.

900 CFM at the top of Mount Everest is not the same mass as 900 CFM in Bermuda

[Nismo_Freak]

BigTone, the build looks good dude. I like the R32 tails, they fit the body lines pretty well.
