video mechanical injected q16

I was bored this afternoon and decided I would clean the nitro residue out of the engine from last night and put it on q-16.

Its seems to have great throttle response idle egts running in the 860-880 range seem to be the best, might make a pass on it in the near future .

Sounds great, revs fast too, very crisp sounding, when do you think you might go to the track?

you aint!

J.Y. , Quit goofing around.....you're gonna get kicked out of the methanol mafia

that's all right if the gaz nazis will accept me.

made about a 3 second 2 step hit with a 4600 chip in and egts were around 970 degrees a little phat as I suspected. Gonna make one with the chip out later and see what it says.

who gives a f**k what it does in the shop, get that biotch to the track, that will tell the tale lol.

J.Y. , now you see what I was saying.

x2! this is gona be good! a real good test of two fuels.cant wait to see how it works.

made a hit with the chip pulled it stayed rich , converter flash about 1000 rpm short of methanol but kinda what you would expect being that rich . Lots of cylinder to cylinder difference on egt heat, plugs and egt probes read the same as the egt. I am not sure if this is directly related to the manifold runner lengths , but acting about the same as methanol on the cylinder to cylinder richness and leanness. The egt temp difference is a lot more severe with the gas though.

take er down the road and see what it does.

So...you are a street racer?

no, but i do road test from time to time. i retired from street racing a few years ago.

They may come more inline as the temps come up and cylinders lean up.

I done a little more tuning this afternoon. I understand Fabio is not interested in garage tuning but I see it as a necessary step before I flat foot it on the track . Anyway I started out with a 130 pill and have now leaned out to a 140 a little richer than Mr Enderle;s base tune up recommendation. The egt's are still a little on the rich side as expected , with still cylinder to cylinder difference which might require some individual nozzle changes which is no big deal.

I will say up front I am by no means a gas man , but I am very encouraged by the rpm this thing is hitting the converter at especially being this rich. Its flashes the converter to about 6350 on methanol for comparison, I made a short dry hop with it and it is very very responsive. I included a short video of starting it and the normal prime up/ lean start of a fuel injection engine and a few little whaps of the throttle.

you and Nick can start the NGRA.........................

when you get as many passes on your p-51 engine as I have on mine I will take that verbal abuse but I ain't no internet test n tuner so you might as well get past that little britches

No more AA meetings for KY !!!!

Mine has more on it than you think, I can only think of one race where I went home after round 1 lol.

why is there such a big swing between the cylinders ?

Nick its probably a combination of mechanical injection being a little sloppy as in it sprays fuel all the time instead of at a precise set crank degree and it being way rich. The manifold is not perfect because there is no possible way to make a single carb manifold perfect for every engine out there , but it is in my opinion the best manifold available for a bbf in other words a victor will be way more off cylinder to cylinder .

I pulled another test with the biggest relief pill I have and it evened up the cylinder to cylinder quite a bit. The logger sometimes does not agree with the tachometer and in this case I verified it because I felt like I was getting much closer on the tune. The logger said 6500 on the t brake and the tachometer said 6250 . Either way I am very optimistic that the Q16 will flash this converter as high or higher than methanol of course a fair test on the track will tell the entire story.

Lucky s.o.b, I can't even idle the maverick with open headers in the driveway, without my whiny 4'2 nosy azz neighbor calling the po po on me. In the middle of a work day!!!

somebody always calls the po po on me too but they take so long to show up i'm in the bat cave with it cooled off!
