can you explain your reasoning in detail? So what your saying is a big wipple would be much better than a P1 for drag racing? What about an F1R or even a D1 to be comparable?

 

id say my P1 gets the job done just fine on my 5500+ pound truck and has already put a pretty bad hurting on someone running a radix with about the same amount of boost and almost identical mods to my truck. I was knocking down the door to 11s on a 95+ degree night at Crandall and with cooler weather I know it will be well into the high to mid 11s in the 1/4. I can only imagine what a D1 with a slightly larger cam and converter would net me. Call it a freak of nature but for a wimpy little P1 strapped to a 6.0, im very satisfied and glad that i did NOT go with a radix, tvs, whipple or anything of the sort. Procharger gets my vote, hands down! And on a side note, one of the radix trucks that i stuck it to has since swiched to a procharger.

 

Thats good to hear! I had a 04 SSS with a 112 Maggie and raced both a D1 Procharged truck, and a STS truck in the 1/8 mi and easily beat both..Now, we ALL had stock converters at the time as well as stock longblocks..I NEVER lost a short race (light to light) in that truck after it was Fully modded(Cam,heads,converter)..But I think what 1slow01z71 is saying that in stock motor/ kit form a Roots blower will get off the line alot quicker than a Centri at same LOW boost levels..Basically out of the box kits on a semi stock truck (x10 for awd) a Maggie will win off the line every time..But I still love Prochargers! but you cant beat the instant off the line torque of a PD blower

 

I'm really surprise about what you say guys regarding the Procharger, The only centrifugal i used with a successful were a Paxton, and then the TVS2300.
It is all depends on what you like, if you wana buy a kit and spend extra cash to make it work good it is up to you.

 

All I know is looking at my times compared to several maggie and tvs trucks with all the same or close mods, they havent had a chance. If you want to base the argument solely off of track times for which blower takes the cake, take a look at the top times for Silverado SS trucks over on the sss.com website. Currently I have the second fastest supercharger only (when i say only i mean no nitrous, etc.) on the site, only to be beaten by someone running a fully built 408 with a tvs2300 (11.71) which I plan to match or beat come fall/winter when we get some cooler weather. Im not trying to toot my own horn so to speak because I already know of a few builds currently going on that are going to come damn close to beating my times and im okay with that, but theyre ALL running prochargers.

 

A procharger with a stall is un stoppable unless you got a nice turbo set up.

 

Diddn't Krambo run faster than 12.04 with his old lq9/radix setup (no n20)? Zach what was your 1/8 mi time/mph? Sounds like a real stout setup

 

No problem, by no means am I an expert, just been around a while and seen what works and have ridden in/driven pretty much all types of setups. I think you made a good choice considering what youre going to use it for. Just be careful with how hot it gets over there and getting overzealous with the timing. I bet youd be amazed what a difference a killer chiller would make.
Out of the box yes. If youre going to start modding it and swapping to a smaller pulley then the difference becomes smaller. The larger the converter and smaller the pulley you run on a centri the more it has an advantage over a roots/lysholm compressor. Just look at the trap speeds of the setups. Zach is trapping 108 at a 12.0 and a radix will trap around 105 maybe 106. The radix would probably be ahead in the 1/8th while the centri will come on like the radix truck threw a boat anchor out.
Well your truck is a beast so it doesnt count

I actually installed a P1 today on a buddies truck. It is by far the simplest kit Ive installed out of all the forms of FI. The only problem I really see with a properly setup procharger kit is top end boost. WHat I mean by that is the small size pulley you need to get boost coming in soon down low can take you right on past how far Id be comfortable with on a stock longblock. "right" and "comfortable" are all very subjective words obviously. Obviously yours is set up "right" but longevity wise? What do you shift at and how much is your max boost?

By the time its all said and done I may try one out if I keep my truck. I do love the whistle at idle
Agreed, if youve already got full exhaust and a decent sized converter for NA performance I think a procharger is a pretty good idea. If youre starting from scratch I think a turbo kit from KB is hard to beat since you save all the money on the exhaust. I like the turbo kits for the fact that you can limit boost with the flick of a switch with no pulley changes. You can run 8#s on as a DD setting then if a little ricer wants to screw with you, hit a switch and be on 12.
Krambo ran an 11.7 on his LQ9/radix combo. Never used nitrous to my knowledge. Trever ran an 11.7 also I believe on his 5.3/tvs1900 combo.

 

Holty also ran a 12.14 on a boost only setup, 6.0 maggie.

 

I have no idea what krambos old times were which is why I said currently. I guess when he went all out on his new motor and nitrous and ran his 10.8 the old times were updated to only members currently running supercharger only and he was moved into the n20 category
