2270 Testing

[MASSIVE TYPE IV]

How I believe it makes more power:

ACCURACY: Put a timing light on this puppy and see the numbers on the degree wheel STOP instead of dance anywhere, and all over the place..Accuracy is important, as in this case it is timing, and when you want to start a burn, timing is everything. When optimizing ignition we start at 28degrees full advance and do a full pull all the way to 34, then look for the best numbers (not max power, best curve) It is amazing what a 2 degree change can do, it may be the difference in burning all the fuel and making power, or wanting to richen up in the top end from not enough advance..

With that said I believe that anything thats as accurate as the Mallory WILL make more power consistantly, just as it has. It keeps the timing where we put it, not where it wants it.

I want EVERYONE here to realize something . I by no means are affiliated with John, or get a commission for selling anything he has. I'm GIVING the enthusiast the most accurate information that we have available, so their choice of parts will be what they desire, not a "Pig in a poke" so don't think that I'm saying all of this because John sells them.. Thats NOT the way it is..

I know what I bolt on, and I know what it does on the torque scale. Like I said in my original post, I see that the DTM works, and so does the Mallory, POINT BLANK! I don't care why it works, and don't have time to disassemble it to figure it out, but it works! The only thing I have found better was my direct fire set up, that cost triple what the Mallory does.

The HP numbers have a nice climb and peak @ 5000 RPM @ 119.7 not bad for a non revving engine. I took it to 6 K once, but could tell that it was not liking it and it fell on its face after 5 K..

Add a TS04 turbo with a high exhaust A/R. It's big, and won't add boost until 4k.

What Jake is finding with the Mallory dist. (the accuracy level) is one of the achilles heels of the original 205 series and 205-905 series FI distributors in the type 4. The increase in available throttle response I got just in rebushing the original FI dist, and also rebushing the holes in the advance weights, taking the slack out of the springs, and putting level rubbing blocks under the advance weights and plate (to keep the weights from cocking)...made a huge improvement. I can't use a mallory with the original FI...but putting in and trueing 3 sets of ball bearings is actually simpler than having new bushings milled. I have found that the axial play...which is amazingly huge in most stock dist. is one of the worst problems for the FI. I have shimmed it out to about .002 axial clearance...at operating temp. Havn't tried it yet. We'll see. Ray

nice info.
but just going off at a bit of a tangent jake can you tell us the comp ratio of this engine i gues its fairly high but just how high?
my gues 9.5-1 close?
how does the bad boy idle does the accuracy of the mallory help out here?

any chance of getting a little snippit of video footage of one of your engines on the net too oogle at:-)

<B>I have noted the advance curves to stay the same on most TIV engines, no matter what exhaust and etc are used...I can email you a set of curves, so you can pick out what you want, it will vary some for every engine, but have been pretty consistant, no matter what changes were made to the engine..

I would like to see that info if you wouldnt mind. I think i will run a few baselines with the 009 and ignitor then switch in the mallory to see what difference it makes on mine.

Thanks

The Mallory does help with idle, but with this particular cam she idles @ 800 rpm like silk, no lope or flat spots...It is getting installed on Monday, I'll let you knowhow it pulls.

jake .
sounds sweet but im gagging to know at what comp ratio your running this little monster and what octance you will have to feed it you said you use amoco earlier what flavour .

id love to be there to get a ride monday.
