BROTHERDAVE i don't know why you insist talking about PI converters ?
"mike has PI convertors, they are the best"
1) I bought a MonsterBox transmission already and that comes with a Torque Converter (total domination 2500 stall).
"make sure you check out others experience with the current jasper monster box transmission."
2) Answer for that is here https://www.f150online.com/forums/sh...ght=monsterbox
"ported heads and stock cams is like taking a shower and putting your dirty underware back on..."
3) Most of the vendors here do not agree with your statement.Just check with JDM, JLP, PSP etc...and etc...
"drop the jackA$$ attitude"
4) Why jackass attitude ?

 

good luck,

you sound like you have it all figured out, 23 psi, 700rwhp and all, i'm sure it will be up and running in no time.

i am guessing you have about a $25k budget to do the motor, trans and brakes.

jump on this one Mike, sound like a potential great customer, he can probably teach you a thing or 2.

 

HI!... Here's my two cents on this :

If GREG EVENS is building the MONSTER BOX your going to install in your truck, it will be the best and take just about all you can throw at it. If JASPER is building it to GREG's specs, I wouldn't touch it. Seems the craftmemship has gone way down since GREG stopped building his own transmissions. If I were to buy one I would pay extra just to have GREG build it himself.

As for the P.I converter, yes they are one of the best. I have ballooned 3 converters over the years and since I went to a P.I converter I have not had a problem and am extremely happy with it.

As for running 23 psi, if I were you I would try like 12-16 1ST and see how streetability are. Mabey crank it to 23 PSI if you run it at the track.

 

Neal, the monsterbox came directly from Factory Tech. I heard that they had some issues in the past but past is past otherwise they wouldn't offer a 2 years warranty including labor. That's a very good deal !

 

All that i need from Mike is his opinion about the cams and buy it from him as he is a CompCams dealer.

 

hi everyone,
need some input. i have $1000 to put into truck, what will give me most bang for bucks?

Thanx, Apaknad(aka Capt. TaDa)

 

My apologize for apaknad.

 

ok, this is just my second post- i am still getting familiar with the site so i am going to make mistakes. how would you have done this.

 

In that case i am here to apologize. Just read the forum rules and take a look around, it's very easy. Good luck.

 

Get the cams. They will help you.

 

Ok, but which one Mark ? I am afraid i choose the wrong one and loose a lot of low end torque. It's not a good idea to beat the stock cams torque only after 4000 RPM or more. Our engines don't rev too high so my idea is monster torque right after idle.
Thanks.

 

the 125150's. You will not loose TQ, especially with the blower on it. You will keep about the same TQ on bottom with it increasing (faster than stock) as the revs come up. It is hard to say what HP numbers will be, but on the 2v motors we usually get a 40 hp gain.

 

Mark, what do you think about the 127300 ?

 

hold on guys, we are forgetting something here.


there is more to this than simple intake and exhaust durations or even ratios. a blower cam needs to limit dynamic cylinder pressure(compression). that is the short reason why blower cams have tighter lobe seperation. the cam comp cams recommends is NOT a blower cam, it is simply the best option for the available cams. number (2).


these motors even in ported form have little exhaust flow to support the massive intake charge. 80 percent is ideal, but there is a margin that extra exhaust duration will fix, but there is a catch.... as the balance biases either direction you will reach a limit that the advantage of the larger flow is stopped. when exhaust flow is maxxed and there is remaining exhaust gasses in the cylinder power is lost. there is no advantage to more intake duration. also, there is only so much available duration that both can use before overlap is too high.


if you use a cam with too little overlap and high dynamic compression, you will need tuning to be careful unless the motor is designed to deal with it.


you will not lose torque, i have said this before. it will shift in the rpm band in whichever direction the cam is biased. toque loss happens when the combination is mismatched.


a badass 4.6 with 400fwhp has 400 lb-ft also. loss? not really. a mach1 has 325+rwtq modded with cams. you can lose torque if you screw up the combo, but not otherwise. use the cam CC says. otherwise get custom cams for a few bucks more and forget this crap. off the shelf cams are ok, but custom degreed in cams make all the HP. no mismatch bullcrap. designed for you not joeblow.

 

Since you asked for my opinion, I would go with the 150s on the cam selection. I would also suggest NOT using a Monster Box or Total Domination converter.
