Dynoed my NA Golf with a Giles pump!! Dyno POSTED

[BejamminR]

Very nice results indeed. I can hardly wait to be rocking a Giles pump of my own.

for the price tho u could just turbo ur car

you'll have to talk to Giles about that one

Turbos suck.... and the big picture is putting a super pump on a TD

did someone say superpump on a 1.6TD? Turbo's blow too :wink:
When the head gasket blew at 3800 rpm on mine during the dyno run
100hp and 120 ft/lbs at 20psi. it was just starting to make power  :cry:

I broke transmision and turbo at the Atlanta Pro Solo,  :oops:  might be a little bit till I get it all back together, and hit the dyno again.

Nice numbers for a bone stock NA tho.  Power is in the pump

Sending my pump to Giles this week for the frankenmotor thats going in the Scirocco.

I should have the mileage results from my first tank in by the weekend I drive too much....

[burn_your_money]

I just filled up.

My previous average mileage was: 43 US MPG

My previous best tank was: 47 MPG

My tank with the super pump: 49 MPG

More to come of course

Am I the only person who is finding all of this hard to believe?

Injector pumps are a mixture of injection pressure, injection quantity, timing of start of injection, and duration of injection.

This post makes it sound like there is voodoo involved.

I just can't believe that someone can take a good running VW 52HP  engine that is smoking lightly at full throttle, indicating excess fuel, install a "super pump" and then all of a sudden the engine isn't running rich and you are getting more HP with the same amount of fuel.  

The TDI's are notoriously under-fueled, but not the 52 HP NA Diesels.

thats what makes a Giles pump worth every penny  he could very well be the best at what he does.

are u implying that tyler would lie?

I was just wondering the same thing with my little truck, I have an AEF engine w/ a Lucas IP that I´ve increased the fueling on. The truck is much stronger now and at the last fill up I got 5.1l/100km, previous best was 5.3l/100km.
Go figure....

My average constumption is about the same, 5.6l/100km now vs 5.5l/100km stock.

There have been dozens of dynos on Giles pumps, both NA and Turbo showing the before and after of what his magic can do.  It's the real deal, and a valid justified reason why his prices are what they are.

I don't find it hard to believe.  I have built plenty of performance gas motors with tweaked fuel injection systems and if I didn't drive them WFO (wide friggen open) I saw an increase in fuel economy.  Gas cars have a complete computer system to control fuel and timing.  Older diesels have a mechanical computer called a fuel pump.

Fuel quantity, injection timing, duration, etc, everything except the injector nozzle is in the pump.  There is more to diesel performance than dumping a boatload of fuel to the motor all the time.  Giles has the knowledge and equipment to improve these pumps resulting in better performance and economy.  I can't think of anyone who has had a bad experience with Giles.  He has great customer service.

I don't doubt that the super pump improves HP over stock and perhaps mpg at the same time, but it would be nice to see an actual apples to apples comparison. It would also be nice to see that comparison be done with a properly rebuilt and calibrated non-turbo pump rebuilt by a third party, placed on a car owned by someone who isn't a representative of Giles and then a Giles pump installed on the same car with a dyno chart of each run. - libbybapa

Much agreeded.

the other thing about the old pump is that if it was factory it was tuned to the spec of fuel from 30 years ago

We put my old pump on the test bench. It preformed quite well, however the governer was kicking in about 1000 RPMs too early. Timing advance/retard was inline with a stock pump and it was actually at the upper limits of the test sheets for fuel delivery, until the governer kicked in. There is no disputing the fact that power was significantly increased well before the governer kicked in, and well beyond that as well

AFAIK the specs for calibrating a pump have not changed, but I will confirm with Giles tomorrow (if I remember)

If anyone wants to send me a rebuilt pump I will install and dyno it where my car was previously dynoed. (I'll send it back of course ) It doesn't change the fact that I work for Giles though. If anyone wants to drive my car, I might let you. Just ask at a GTG.

Compression on my engine is either 350 or 250 all across the board. I know that's a wide spread but I used 2 different compression testers and those were the numbers I got from each gauge. Obviously one is wrong and I'm working to find out which number is correct.

I don't doubt that you did get more than 49 MPG Andrew, and your driving styles most likely were the key difference. Or the fact that my tranny is on it's way out (bad bearing somewhere in it) Either way though, the pump alone has improved my fuel ecomony with little to no change in how I drive. I say "little" because I probably accelerate faster now that I actually can...

This is also of course only 1 tank, so who knows. I do go though a tank a week and a half to every week so updates will be fairly constant.

Actually if anyone has a rebuilt pump from a third party I will temporarily trade you for my old pump, do a dyno run and then send it back.
