that engine snap is a killer! Super list of mods... Guess you set a good benchmark for other tuners.

I dont see why you would need that much fuel flow in the first place for an NA car.
True, even 240CC should do, but by using 8 injector setup they must have planned something, nitrous may be, which i think Kartik can only clarify. that's why 350CC i posted.

Oh my giddy aunt! This modification is Off one's rocker. I had heard lot about Wolf's car but never got a chance to look at it. I liked the Dual fuel rails and Custom Individual throttle bodies, with 8 injectors. But like other why 8 injectors? When there is lot of options on 4.

@Ford Rocam, vinayvetc, This kind of system is used on High reving NA engines by Honda and most bikes, It's all to do with fuel atomization.
After around 7000rpm the fuel does not have enough time to atomize till it reaches the cylinder and so the second injector bank at the mouth of the intake kicks in and the length of the intake gives the fuel enough time to atomize properly.
In turbo cars this is not an issues as the intake air flow helps the fuel to atomize do to the swirl cause by the forced air.

NA it may be Sub 8 seconds it may do, but just look at that engine bay, that shows a lot of professionalism ,the best performance mod on a car which looks neat and i hope it'll be reliable too .

Still can't take my eyes of that engine bay.

Its true that motorcycle engines use secondary injectors.

So the specs are out finally! Eh Ritesh?
I was dying to see the specs but all we could get is the time sheet pasted in your garage. Since you mentioned that you are a part of a race team and cant disclose the specs.
Awesome ride bro!
Where is the air-intake/filter/intake manifold/plenum?

OT:
Guys why is there no info on the web about the B15 series engine? I thought the Indian V-TEC and NON-VTEC engines from Honda are D series engines(D15B7 non-VTEC SOHC and D15B VTEC SOHC) but the engine number on my car always confused me as it starts with B15B9 and as mentioned earlier the Indian VTEC versions are B15C2. But i cant find any info on the B15series.

Ok with the point Jittu brought up. He's right. A much simpler setup with 4 high flow injectors would suffice along with a single fuel rail. That is unless FI or nitrous are planned.

But FI is NOT on the cards considering it's a high compression setup, so why??
Wait no scratch that even with a FI or nitrous cars do fine with a single set of injectors...I'm confused

Next is this car daily driven? Cuz can someone please tell me what ITBs are doing on there if she's to be DD in Bangy traffic

Clean work though, love the bay, and the ITBs even though I can't figure out their use unless she's a drag car, look AMAZING!

@DocG:I believe Ritesh uses the car mostly for drags and races. Infact this might be the first time the specs of his car have been revealed on the forum, and not many people use a 4x1 header set-up for street use.

Found a valid thread to discuss Honda engine codes:-
http://www.team-bhp.com/forum/sedans...ohc-1-5-a.html

Though i believe it is in the wrong section and should be in Technical Stuff.

Nice work and lovely engine Secondary injectors should work well towards fuel atomisation at higher RPM. My understanding is that as engine speed increase time available for proper atomisation reduce at the same time intake velocity is high this would shear the fuel along the walls of the TB if it's not atomised properly. The secondary injectors at the back may atomise the fuel better since it gets more duration to mix with the air before it enters cyl head.

Finally. It has made it here. Good work by team RD, and an even better initiative by choosing their flagship performer to be showcased on team-bhp with detailed specs, a surprise since most tuners believe in holding their cards close to their chest.

Can you shed some light on which car you are referring to? World's fastest NA drag cars (in dragster chassis)are all American V8s- they do the 1320 in the range of late 7s to 8s, and don't rev to 10k either.

Coming to sport compacts, and more specifically Hondas- brings Bisi Ezerioha into the picture. And I'm sure you would be aware, he is doing mid 9s with his current setup- a 460hp monster F22A in a Honda Insight body called the Stitch, running ITBs and eight injectors controlled by AEM EMS. Bisi said that it was done in a bid to up the atomisation- and this is from a guy who was using carbs to break into the 10s with his D-series powerd CRX.

Is this the car you are referring to??
