How high can an N/A get?

OK, if I'm reading your procedure correctly, altering the WOT stop screw is doing the same as the governer mod?  The only difference would be you'd be getting the additional advance when at WOT? 

No tweaking the fuel screw?

No it really wouldn't be the same. The spring would push back against the gov and limit fuel.

But Lucas you are pulling the springs completely tight by pulling the whole governor assembly at least an inch passed its intended motion. Explain to me how I can quickly spin up to 5000 + ? if it were limiting fuel?

It's probably not giving it %100 of fueling, but its a hell of a lot better then %20 eh?

nah my post was about the wide open throttle screw. I don't think it would be the same as the gov. mod.  It might be, but I might not be thinking correctly about what is going on.

I am a full fleged member of the gov. mod crew  and completely agreee with you on how awesome it is. I had 2.5" exhaust, 3" pvc custom intake, and the gov. mod and it would pull like crazy. I had to watch myself on the freeway. I used to struggle to keep up with the 70MPH traffic. After the gov mod I did my usual floor it on the freeway and looked down...I was doing 84 MPH and still had more.

I could most certainly hold 75-80 no problem on the highway before doing this half-mod as we will call it.. however this does not really change anything unless your foot is on the floor. IT for sure did something, not a substitute for the gov mod, but maybe a slight alternative for those not willing to open their pumps quite yet.

"How high can an N/A get?"

I dunno, how tall is the nearest mountain?

Because nobody's made -that- crack yet in this thread...

195/60-14 tires. 1st thru 5th gears respectively, are: 3.455, 1.70, 1.065, 0.778, 0.600, and R&P is a 4.111.

That is a respective 3750 rpm. With the Gov Mod, fully attainable. 

It appears my friend was incorrect

Now lets say for arguments sake I found a way to do the Gov Mod without taking the pumps top off... Yet I kept the fuel screw at or below stock settings to keep the smoke as a gray wisp behind the car, or not even there at all. I have researched and tested a method, that effectively does the WOT part of what the Gov Mod does.. with nothing more then a wrench and screwdriver.

The full throttle stop is what i messed around with, and after talking to a local yocal around here that deals with these engines/pumps as a hobby. We came to the conclusion that if you were to back to the throttle stop out all the way and then manually move the throttle arm through its entire motion to where it doesn't want to turn anymore, and then bringing the stop screw to meet it in this position.. your effectively "Shimming" the governor assembly solid. Instead of taking it out and adding springs, and making the gov mod active %100 of the time and at all peddle positions, we now only have this full fueling when at WOT.

I tested this theory on my bone stock 1981 1.6 N/A, stock intake, stock 1.5" exhaust, and stock pump. I originally had the fuel screw turned in about 1/2 turn just so i could get the thick black smoke on those hard WOT pulls, it bumped my idle to around 1050-1100 I'd say. So i backed it down to where the idle sounded closer to stock or lower, probably 900. Did the adjustment to the throttle stop and went out for a highway test.

The 400m on ramp alone showed 112-115mk/h for an RPM of 5100-5200 in 3rd with my FF trans. It kept pulling a little bit more but she was screaming, so I grabbed 4th and quickly (Not usually heard in context with a 1.6 N/a) climbed to and passed 130km/h. Last night I had absolutely no problems keeping up with my Gf in her 90 with the 1.8 whilst cruising the back roads.

I suggest anyone with a 1.6 N/A and bone stock pump go try this out, because I can vouch it is fueling... I wouldn't have pulled to 5200 in 3rd if it weren't

i messed with the WOT stop. tried all external adjustments on the pump. nothing made as big of a difference as doing the gov mod. theres no way anything on the outside of the pump can do what my 2 stainless nuts in the pump can do to throttle. i took my full throttle stop out, and advanced my throttle arm a spline. the gov mod is the winner in my books. how hard is it to take off the throttle arm and 4 screws? that too hard? i personally dont mind opening up my pump once in a while, just to tell how its doing.

I'm not saying its a substitute, but it most certainly is doing the exact same thing for the WOT portion of it..

It is not an external pump mod, It is pulling the entire governor assembly an inch past its intended motion ever was. That makes it internal, by changing how tight you are pulling the governor together. I am not lying, my engine will fuel and pull all the way to 5500 with stock intake and exhaust. I'm sure it would pull way more if I had these two modded. Fer Sure.

I'm not bashing the gov mod, it does the full fueling at all throttle positions. There is a lot that can go wrong to a none experienced person opening one of these pumps. Smallest fleck of rust could eff up your day severely.. why chance it?
