@Pranav, Would you like to get your car Dynoed anytime soon? I could help.

pranavt · 20th February 2010, 21:45

Yes, that's the plan. I've been too busy to sort out a few unrelated things with my car, so it should happen once it's all done.

ya dude you should do the dyno run soon, will be very interesting to see the results.

abhipuru16 · 20th February 2010, 22:57

What is "FFE'd". Sorry, I am a noob here.

pranavt · 20th February 2010, 22:58

Got a freeflow exhaust. That was quite a few full moons ago though.

pranavt · 4th March 2010, 22:47

So yeah, first of a few videos. Expect a few more in a few days

Car sounds great and looks quick. There seems to be some sound just before you start accelerating after changing gear or retarding. Is the engine running rich fuel mix?

pranavt · 5th March 2010, 01:31

Yes, the engine is running rich right now, though that's only because I'm tuning it and it's in open-loop. The ECU will automatically decrease injector pulses once I put it into closed-loop. As for the sound, that's because I recorded it using my cellphone camera and it didn't seem to pick up sounds properly. There are quite a few things which seem to be recorded at a different level altogether. In reality, the car sounds a lot meatier than this, and dare I say it, almost like a B16/B18. There's still a lot to be extracted from the current configuration. Today was just a shakedown run for an hour or so, and the meat of the fuel/ign tuning and various other things like battery offsets and fuel/ign corrections are still to be done. Time, sadly, is a scarcity and that's what keeps delaying everything, though I aim to get done with this in the next week or so.

lol can you get a better horn?

pranavt · 5th March 2010, 01:43

Refer to previous post, it sounds different. Even I am embarrassed by the end result

pranavt · 9th March 2010, 20:11

So I'm opening up my engine for head work and putting in the Y8 cam that I have lying around. I'm planning to go for an aftermarket head gasket, preferably a Fel-pro. Would anyone know if they're sold in India? Any other brand apart from OEM and cheap Chinese knock-offs? And if not, would anyone be willing to use their connections to get a HG shipped to me via one of their friends/etc? Thanks in advance.

pranavt · 9th March 2010, 21:05

Meh, nevermind. People know more about seat covers and power horns these days. Decided to go with OEM gasket as per ROCAM's suggestion. Thanks though.

pranavt · 17th March 2010, 18:21

Time for the next stage of my DIY job. Putting in my new cam with adjustable pulley, probably bumping up compression a bit, porting and polishing, 3 angle + backcut valve job and valve seat work. Should be fun
