NPI vs PI faceoff

[justinschmidt1]

Oh yeah man, for sure. For the most part i picked up the engine so i could work on it and build it up while still maintaining a daily driver. What kind of bolt ons were you running on your NPI? (gears, headers, intake, etc.?)

hmm pi intake, 3.73 gears, long tubes basically.....

It was a stock stalled auto tho so that hurt be pretty bad.

If I had a small 3200 stall or something Im sure the car would have went mid 13s all day long

Its an upgrade, dont get me wrong.


But pi vs npi isnt huge normally




I ran 14.0 @ 100-101 with my bolt on NPI auto all day

pi cars are overated, theyre not much to beat

compared to the red headed step child non pi, and you being a fellow driver im shocked to hear that you think the Pi is overreated, when pi swaps are a BIG deal with your cars to make power thats why every 1 does pi swaps lol and its about what 45+hp more then a non pi, and pi cars 99-04 seem to run mid to low 14's 1/4 stock and trap 95-100 bone stock, when a non pi 96-98 runs 15's 1/4 trap @82-90+mph

and whats the point of saying ur bolt on modded no pi ran 14.0, when a pi car with an auto can run low 14's bone stock?and it takes no skill in a slugomatic to just floor it, if you had a 5 speed you prob wouldnt of even ran anywhere near 14.0 you would mid to high 14's best with a manual, and op just got lucky a pi car with them gears and bolt ons is a strong 13 sec car with a better driver. for example my friend with a 2004 gt auto ran 14.1@101 bone stock,and he ran 13.4-13.6@103-105 in his stock 4 valve mach1 so I would say the 99+pi cars and 4 valve cars are a alot better then a non pi stock or with slight bolt ons even against a stock non pi or stock 4 valve car..

I dont want to start a pi vs pushrod war or the pi vs non pi like this thread... but I can say the same about my 5.0 pushrod vs your year non pi, My car bone stock was running 14.6-14.8@93-95, and my other friend with his 1996 gt non pi with intake and exaust on same day was running 15.1-15.5@87-92, his best time was a 15.1@92,which was still slower then my slowest time in my stock 5.0.and his wasnt stock he had bolt ons and still slower then my stock 5.0, So yes I would say a pi is a BIG diff vs non pi cars :thumbsup:

Wow, that must have been on hell of a bad driver.. That E/T is at least .5 off on the PI car. 4.10's alone should have him in the high 13's.

you won out the hole thats it.

my buddy has a 00 gt VERT AUTO with 3.73s, CAI/tb/plenum, and a predator (tuned by me) and rips 8.7s on street tires in the 1/8th with a 1.92 short time, all at 80.5-81mph......

both of you have some work to do in the driving department.

For one, saying I wouldn't have ran a 14.0 if I was manual is stupid because generally cars that run those times benefit from the manual since it will put down more power unlike cars that run 9s/10s/11s/12s and have built stalled autos, then the auto becomes a big advantage.

Maybe if my car had a vb and a 3500 stall at the time I would agree with you about never touching the times with the manual.

The auto doesnt really have the advantage when comparing 14 second cars and a stock stalled auto.


I was trapping 101-102 mph when I was NPI auto at 14.0, those trap times are good for mid 13s.


Where the hell did you get the idea that stock NPI cars trapped 82-90 MPH?

My car bone stock NPI motor ran 14.6@ 97 mph

You didnt seem to understand my point.....
And my point was that a good driver in a NPI car can beat a bad driver in a PI car because the PI cars arent that much faster.


PI is better but if you were to go from say a bolt on NPI car with a pi intake and throw PI heads and PI cams on it your not going to be like OMG this car is a ROCKET WOWOWOWOWOWOWOWOWOWo


I have a PI motor in my car, dont get me wrong, its better but its not like going from a singleport 3.8 to a 4v 4.6 cobra

Its more like adding a 25 shot of nitrous...lol

 

[justinschmidt1]

its like hey man I went from my mid/high 14 second NPI to a low/mid 14 second PI. now im UBER badass

This is why I didn't go the extra mile and get the full PI swap for the extra 10rwhp, just the PI intake and cams for me. In total, really not that much difference. Remember guys, All PI stangs came with 3.27s and only some of the 96-98s came with that option along with the less 40rwhp defecit. With a possible wide margin in gears, stock vs. stock, it could be close to 1 sec. by the end of the 1/4 mile and that's quite a bit for that distance. My 1st time at a track, I ran a 14.3@97+ mph with just PI cams, catted X and the optional 3.27s from Ford.

no need for 2 topics, I merged the two, enjoy !! :thumbsup:

Yea exactly.

A straight up pi swap is not worth it without cams/headers at the same time at least, to me.

Theres definitely no 40 rwhp difference....even at 225 to 260 were talking 35 engine hp which is probably more like 25 rwhp which 10-15 of that seems to be made up with a pi intake

96-97s were rated 10hp less than the 98s at 215hp and the dyno numbers I've seen posted it's not too uncommon for a 96/97 to dyno somewhere around 185rwhp and 98s around low-mid 190s with 99+ PI stangs in the upper 220s to low 230s. So a real 40rwhp difference to most SN95s.

Sea level can make a huge difference too, and age/wear. My worn down 5.0L at 1500 meters of elavation bested a 15.1@92mph with a 2.3 60 foot. This was with all original everything, just a catback and 3.73s. Granted, With better traction I probably could have gotten a 14.7ish, but I never had time for another pass. Stock 3v's are running anywhere from 14.4(the average) to 13.7(best drivers), and these are cars that are *suppose* to run 13.6 from the factory.

Thats irrelevant due to the driver.

The 05+ gts around here dont all magically run 13.6 cause im at sealevel.

Most of them run 13.8-14.3 depending on whos driving.

Ive seen a lot of modded ones run high 13s but thats mostly driver I would say.

theres one auto guy qwho runs 13.0 with like 3 bolt ons, tune, intake, and mufflers

 

[Venom351R]

Thats horrible to cut a 2.2 60' on Nitto's. Not the best track tires out there but damn thats even high for street tires. That guy sucked!

 

[Rice_slayer]

I cut a 2.3 60' on my BFG KDW's... then again, I don't claim to be a good driver, I suck

thats HORRIBLE!!!!!! with 40psi in some kumhos you should be able to pull 2.3s LOL

 

[Rice_slayer]

with 40 psi I pulled a 3.2 60' . What now!! Seriously, that was not a good day .

 

[duff daddy]

well boys we need to start seeing some 1.7's and 1.6's out of you kiddies this summer!!!!
