Thanks for the feedback guys !

For daily drive, the car has a custom fabricated manifold with 4 injectors

The primary smaller injectors are programmed to work at lower RPMs and loads, for higher RPMs and loads, the secondary injectors take over shutting down primary injectors. All our logged data indicates an improvement in combustion in this setup , but the parameter specs required to get here are quite vast. The car is built to be used as NA, atleast as of now

@Rocam, injectors sizing was done with respect to revs and other injection phase related factors.

But what i dont understand is that Wolf's car is expected to be producing around 140-145bhp which is about 95bhp/ltr. So basically you'd expect it to peak somewhere in the region of 7500-7700rpm. When i say peak, i mean max bhp rpm.

Now a stock B16 produces its max power of 160-170bhp (100-106bhp/ltr) at 7800.

And i dont think the B16 uses 8 injectors. Even the old S2000 did 120bhp/ltr@8200rpm with 4 injectors.

So at what point does a tuner decide that 4 injectors are not enough.

Could you please let me know which car/engine ? If possible link, tried to hunt for it on the net but all I could get was B18 and B20 with no specs or some with 8 injectors and a V8 power dragster running a 1300 BHP engine.
Would really like to know more.

Karthik,
What is the top speed. Do you guys drive at some runway . What is the power and torque that the car produces after all these mods?

Thats a superb build Karthik and team. Very clean and well executed. An impressive list of mod's which I'm sure took a lot of time, effort and patience from the tuners and the owner.

I've driven this car long back alongside Ritesh but I'm not sure if it had all the mod's then, but it sure was quick as hell. This was at one of the meets at LCD. And with Ritesh behind the wheel, the car was very impressive.

Finally the cat is out of the bag eh? Fantastic Job Ritesh, RD and RAC. I have admired this car right from day one and this is a clear case of a man in charge , making the right decisions for modifications on the right car with the right tuner support.Its just like a fairy tail, man does this car move. Fantastic mate! Really envy your ride and may you take it to greater heights!

Ritesh, why don't you just right a review on the cars journey till now and things like reliability different setups and those tarmac burning drag runs where nothing really came that close to you.

P.S/O.T: I have an old run of you against Shabbir in the yellow city just side by side racing right through the finish when you just got the better of the other car!

Makes sense now, is there any time delay from switching from primary to secondary injectors? or you switch on secondary first & then shutdown primary?

Just wondering, what metric are you using to indicate improvement in combustion?

Wow, thats quite an impressive list of mods, and to hover around the 8 sec mark the car must feel like quite a rocket !!

Havent really tried multiple drivers at one time yet , just kiddn!

We have managed a 8.02sec run with full load + 1 passenger during an Overdrive Magazine test (chk last months edition)...so mid to late 7s should be achievable in race trim.

No NA Indian car has officially broken into 14s in a quat mile, hoping to stamp that position this month in mumbai. Prayers guys...

@Flyingspur: The whip lash at launch is a rare feeling in Indian cars, here's one...

Wow. Just Wow.

The professionalism gone into the build is evident from the engine bay pic.

@The Wolf: Any specific reasons for sticking with NA and not going the FI route?
