Hi,

regarding the gasser, the 1.8 ltr. mk1 gti engine dx, could rev stock above 7000 rpm,
my dx rev all up to 7500 rpm, but i think to remeber that stock redline was 7200 rpm.

Here is a video of my aaz (in a golf mkII) wringed all out to max rev. I have to say that the rev counter could be not
highly accurate, but by looking at the speedo it fits good. Its a CTN (02a) engine and 205/50/15 tires. It has a K14
charger and a 7mm chimed governor.

I hit ~50 km/h in first and ~90 km/h in second, with is both between 5400 rpm and 5500 rpm.

whats a DX?

cause we never got one in north america..

Hi,

the dx is the (famous) 1.8 ltr. golf gti (mk1) engine with 82 kW (112hp).

Here can you find nearly all Golf engines with basis data:

thats why we never got it, was germany only..

[8v-of-fury]

Sounds like a great engine for the mk1 though

16v... thats all i got to say.

fuel cut was around 54-5500? is that what he said at the end?

thats about what i experience too.. and it flat quits pulling by 5750..

[RabbitJockey]

it sounded like 6400-6500 to me but the quality is not good  if its thats high that would be really really interesting and if we could make power even in the high 5k's power capability would jump considerably

my car pulls GOOD to 5250 or so.

i think the fuel cut was around 5500, if it was just cutting fuel at 6500, it would be enough to get the engine to 7000 revs in neutral, and we all know that aint possible..

[8v-of-fury]

He said 64-6500.

Also gotta remember this is a "superpump" But Giles did it right there on video.. so it is possible.

[RabbitJockey]

On Dave's Franken engine he had good power to nearly 5500 on his dyno u can see.  The limiting factor could be the rate at which the fuel burns or even just the length of the injection process in the 1.6td sae term paper there's a graph showing the start and end of injection vs rpm. I would think this could be helped with a bigger plunger maybe.  Giles just shows the pump works properly up to that speed. It'd be amazing if a 1.6 could make power up there and it'd be radical if a 1.9 did

[8v-of-fury]

Ahh good point Trev, very good point. Just because the pump is capable of pushing fuel to 6500 doesn't mean the engine is capable of burning fuel at 6500.. I wonder if a slightly lighter more volatile fuel would make a difference? With lubricity taken in to account as well.

giles has gotta put stiffer camplate springs in there if hes getting 1000 rpms more power out of the pump..

like i said, i have a basically brand new pump, everything is right, it runs awesome. but it still will only spin 5750 rpms with my foot to THE FLOOR in neutral.. it makes 5 psi with the rollers skipping.. wonder what kinda power/boost it would make if it could pull another 1000 revs?

again, my governor is shimmed solid.. theres no way my governor is working, and limiting engine speeds to 5750 revs..

yes, eventually, as you spin more and more RPMs, the flame speed of diesel is exceeded by the speed of the engine.. read as: diesel is still burning as it is exhausted from the engine.. a bigger plunger may help to get the fuel in there quicker, but idk if that bigger plunger is going to help any with an engine that is exceeding the burn speed of diesel..

if we want more power up high, we MAY need to figure out some sort of injectable that burns relatively fast, but are controllable!

lets do some acetylene injection!!
(i imagine if someone in the states did acetylene injection on one of their engines, i imagine the head would leave the block, and it would probably be Catlin, Matt, Eddy, or Jeremy that ended up finding the head)

diesel burns slow, thats why it makes soo much more torque..

i think you and i are on the same track of thought here buddy!
