GSK.. And 0-60 times

[JIM S.]

its true!

... Come on guys, does the GSK really make THAT BIG a difference?

trust us... . it DOES make that big a difference! and I dont think it adds any more stress to the transmission... not much anyway,cause your not really adding a bunch of power, it just lets the engine make power clear up to the 3200+ RPM mark( or 4000 RPM with that kit) . insted of the surge of power, then defuel, then it shifts and another surge of power, then defuel again, lockup and surge of power, then flatness!!:{ . with the GSK its just power all the way with some shifting in there somplace... . it rocks Oo. Oo.



word of warning. . you will probably get a bit worse fuel mileage... ... ... . for a while... . cause you will be gettin on it alot to feel it.

anyway. . I need to stop going off about it. . but it really is a mod that should be done ASAP!

OK, OK... . I believe you!



Does it matter that I already bottomed my hi-speed idle screw? ... . will this effect the GSK kit or does it even have anything to do with it?



Thanks again!

I am not sure if it affects or not ... ask Piers when you call to order a GSK!

By the way I am NOT affiliated with anybody! ... wish i was... I could get free stuff!

Would the GSK help a 98 12v? I do feel the defueling empty and really feel it when pulling a hill with a heavy load. Next month I'm buying a pacbrake and was wondering if I should just get it from Piers along with the GSK and HD valve springs.

Yes and Yes.

I dont believe that a 4K spring kit will be much advantage with an auto trans. Check and see if the trans will let the motor rev that high, I think a 3K works good. Just something to checkout before spending the money. The 4K works great on 5spd. I dont have the HD valve springs and havnt noticed a need for them but am not a hard core racer just have some street fun now and then.

 

[HoleshotHolset]

If we take the theory behind the 3k kit and then go above and beyond it with the 4k kit, you'll see that it's capable of making even more fuel available... . even if you don't rev it to 4krpm.



By delaying the point at which it starts to defuel by using the 3k rpm kit... you are getting more power from idle through rev. limit. By delaying this defuel point even further to 4krpm... . you'll end up with even more fuel throughout the range... . even if you never rev. it to 4krpm.



I could be wrong, but the logic jives... .

holeshot... I think you are right. . but I think what Deezel1 is saying that the PCM that controls the trans might have issues with reving that high. although I am thinking it wouldnt make any difference... . but what do I know.

Matt, I understand what youre saying, but I thought the difference between the 3K and 4K kit is the valve springs?

Can someone confirm this?

If that's the only diff, I dont think your theory works. That is IF.

The 4K gov springs kits are not the same as the 3K gov spring kits.

4k's have one extra spring in the center of the spring pack.

Closest to the retainer stud. It only comes into play after the other springs have already begun to resist the forces of the flyweights.

Additionally, there are different seats for different pumps the springs ride on or in.

The extra valve springs are for more valve float resistance at the higher rpm ranges the 4k kit is capable of.

Eric, the 4K kit comes with 1 more gov spring + the HD valve springs. Based on another thread we recently had here... .



... . The 3K kit as 2 springs per side. Long with the existing idle spring gives 3 total springs per side installed in the gov.



... . The 4k Kit as 3 springs per side. Long with the existing idle spring gives 4 total springs per side installed in the gov. Then there are the valve springs.

PCM... . Heck, my truck don't care what RPM it's at (47RH).....

Shift points only matter if you want it to shift at the new rev. limit. I didn't install my GSK with the intention of using it at 3krpm on a daily basis... . being able to go 'there' is nice, however. The added power throughout the range, is why I did it... . and am I ever glad! Cruising at 75mph isn't such a chore anymore...



I might have to upgrade to the 4krpm set some day... .

Thanks Don and Sly. I stand corrected.
