Sorry I meant AFR...air fuel ratio gauge. Getting mixed up with all these gazzlion acronyms in my head.

Guy's ... Guy's I have just begun and I know how to go about solving them. I just started putting up the turbo on to the existing setup on the car with a standard fuel pump... Lets just list out the current set of issues to be sorted:

1) Had to get my exhaust redone (Completed)
2) Timing was way off for the turbo (Completed)
3) Had to tune her a bit rich (Completed)
4) Have to add a progressive fuel pump (To be done)
5) BOV (Not Reqired as I have left a .5 mm pipe out of the plumbing to bleed the pressure - Gives a lovely whistle from 3000 rpm)

And this is not an MPFI setup but a carb'd blowthrough setup.

However on Sunday Morning Rudra, Anoops and Myself took up a 160 km drive to check out the car and have a great start to the day, on the way up the car just refused to go beyond 3000 RPM and the temp gauge hit 110. At Kolar I fiddled around a bit and got the temp to remain steady at 100 and changed the timing to allow me to rev up to 4000, on the way back she really moved even though she was running lean (She still is till I can get myself a new fuel pump).

Will update again once that is done

Just completed fixing up the fuel pump and here is the first day report on the same:

Current Max RPM at Max Boost: 5500 @ 8 PSI
Turbo Starts Spooling at 900 RPM
Feel positive boost at 1500 RPM
Turbo Kicks in at 2200 RPM
Get to Max boost @ 3200 RPM
BOV: None have left a open pipe to let the steam out (Love the sound of it)

Well the first test was to launch the car and check it out tried it on a dirt track for the first time. Launched @ 2000 RPM and took off with the wheelspin got a bit of traction and the turbo kicked in and wheelspun again and then ran out of road.

I then moved on to the ring road and ran the car to 4200 RPM (am not able to get any more power beyond this today will work on it.) through the gears and surprise surprise it continued pulling at the 5th gear, dont ask me how much I was doing coz I never bothered to see the speedo was busy with the traffic and listening to the whine of the turbo.

The addition of the fuel pump, retuning and the timing adjustment just got rid of the knock that I was getting before. The temperature gauge is also under control now doesnt cross the 90 deg mark. The car is a dream to drive now .

As for the FE :
As soon as the turbo went on I had been pushing the car to the limits each day every chance I got to try and figure out the worst FE reading I could get.

Worst FE Before : 4.2 KMPL
Worst FE after the turbo : 6.8 KMPL

The engine now feels a lot more smoother and I am getting a better power curve than before, am able to cruise easily at higher gears on lower RPM's. Downside of this whole experiment I blew a tyre, got a puncture and hit a stone that tore the sidewall(need new tyres).

But the whine seems to have me addicted and am tempted to accelerate just a bit more to get there quicker (need to kick this habit).

Psycho, do add a nice BOV. if its a turbo, it has to have a BOV.

u'll get addicted to the BOV noise,once u install it.

i still cant forget the BOV's sound from JD's EVO 6.

Quite ingenious!...but won't this also let the dirty air in. BOV is a one-way air valve.

Most modded Conti in the world? Probably.
Dude, what have you done about the brakes? What's the power output now?

Well true it would but I have also placed an air filter after this pipe effectively negating this effect.

The stock brakes have been modified and the brake bias has been adjusted for better stopping power, never had a complaint off them.

As for the power output I will have to time a quarter mile run to calculate it.

But, wont this only tell you the power out at the wheels and not at the flywheel.

Well here is another update ...

Have sorted the problems of leaks out and changed the carb to a conti carb now and have rejetted the same to get rid of the fuel leak problem, the car behaves like a stock conti till about 2200 rpm and then all hell breaks loose till 4500 rpm the Boost meter shows that I am holding up to about 7 PSI but the best driving through the gears is at 5-6 PSi beyond which I almost lost control of the car, hence I think I will stay at this boost power for a while.

Looking back at what else I did yesterday
- Held 10 PSi but couldnt stand the sound of the wastegate
- blew the plumbing apart
- blew all the belts on the engine

and have a chance to sit back and say what a learning experience. Just have to add a K&N to increase airflow to the turbo now.
