Ok... well when you swap PI stuff onto a non-PI shortblock, you make more power than a PI car. And when I say "full bolt-ons," I'm including LTs. My car with LTs/tune would be about 280-285rwhp, and a PI-swapped non-PI car has around 10.1:1 compression, vs. 9.3:1 stock. So... about 290rwhp. IF it has longtubes and some choice other mods. And I don't know too many people that go through the trouble of the PI swap, without doing LTs.

Edit: And FWIW, 9.0 is kinda weak-ish for having 4.10s... I'm sure you got that 8.3 from the Formula because it was an automatic.

Am I missing something here? You gain 110 RWHP from a PI head/cam swap and bolt-ons on a 96-98 GT?

Irunelevens

Full bolt-ons... definitely possible. I'm sure it won't happen with every setup, but it's possible The heads/cams/intake is worth approximately 50-60rwhp. You swap PI stuff on a non-PI car, and you get *about* 240rwhp right off the bat (no mods). And alot of people mill the heads down a bit for more compression.

The P.I. Swap does help those 96-98 cars alot ..... FWIW I've seen a New-Edge Gt M5 with Gears, Exhaust and Handheld tuner go 8.60's in the 1/8, don't remember what he trapped though, that was about a year ago.

well the 9.0 was in bad weather conditions while the Formula was in perfect, very cold weather, but bottom line 2V's are dogs w/o forced induction.....I have had 2 and I am not biased, just ready to admit they are very weak motors period. A friend of mine had an '02 GT M5 w/ every bolt-on under the sun, plus Comp stage 3 cams (XE278's) with a tune and it ran 12.80's, for all the money in that car 12.80s were'nt too impressive...I dont mean any disrespect but there was a reason I got rid of my GT instead of putting more money into it....but if I could have afforded an '03-'04 cobra then that is what I would be driving but for now the LS1 is cuttin it

Irunelevens

Well I told myself I would never get another 2v 4.6... but this car popped up and it already had all the mods in my signature, and I couldn't really turn it down. It wasn't my first choice (or 2nd, or 3rd), but I'm making do. And I'm relatively happy with it, for what it is.

Edit: BUT, (again, FWIW) I know a guy from another forum I'm on that went 13.2 w/ 4.10s, intake, and exhaust... that's not too bad. But he is a badass driver

Same here with the "never another 2 valve" vow. I loved my GT, but it took ALOT of money to make it fast, and it was almost to the point where every time I went full throttle I was expecting something to break. All my Mustang buddies were pissed I jumped ship, until they rode in my car. Literally my stock SS pulls harder than there almost full bolt on GT's(they dont have LT's, but everything else you can buy) My next Mustang will be a 4valve for sure, hopefully a Mach 1 or a Terminator.

Me and this local kid had this argument about his 98 GT. He swore it would make 300 rwhp with the PI swap, and I laughed and said MAYBE with LT's and every other bolt on possible. He then called me an idiot and told me to do some "research".... His only bolt ons are dumped flows, TB, CAI, 4.10's. I cant wait to bust his *** when has his supposed 300 rhwp

gyrene2003

its funny because wont a lower gear ratio than stock lower ur dyno #s, like having 4.10s over 3.XXs, so if thats the case then the guy above isent very smart that thinks he will be anywhere near 300. Got a buddy with an 02 GT with every bolt on but L/Ts did 240/260 and he has 4.10s and is a 5 speed, he almost cried when he showed me the dyno sheet. he then said that he ran on a computer dyno or some **** and ran a best of 14.2. i told him it was time to skip NA and go straight for the blower!!

Irunelevens

Yeah... you can add about 10rwhp over a PI car for a PI-swapped non-PI car. My car has literally almost every bolt-on possible except LTs, and it's untuned. So I'm hoping for 280-285rwhp once I get LTs and get tuned. 300rwhp is POSSIBLE for a PI swapped car (especially if they bumped the compression up even more), but it's not common, and shouldn't be "expected"

Irunelevens

That dyno was messed up... or his car is sick.

gyrene2003

well, i think his car is sick, he said it was a mustang dyno but he doesent know dick about cars and bought it with the mods already done to it. i tried to stop him but he just had to have it. I must say this, its definatly the LOUDEST bolt on stang ive ever heard. i think his car is in need off a real tune not the shitty street tune the guy he bought it from said he gave it with a hand held tuner.

Irunelevens

Yeah, something's up... the guy that went before me on the dyno had basically the same mods as me except he had LTs, and he did 280/312.

My buddies daily is a PI swap, gears, stall, exhaust and it runs high 7s in the 1/8th.

Not until 3rd gear would I start putting a mean pull on that car in the Cobra.

Irunelevens

Yep... they definitely run. I had a '98 I was gonna do the full PI swap on, but I only had the chance to do the cams/intake. Even those made a HUGE difference (about 35-40rwhp at 6,000rpm)

ponygt65

Don't forget upper and lower intakes...that would be a nice addition to PI h/c swap.....it seems EVERYONE that has talked about PI swaps have forgotten about intake work as well. That will put a non-pi car in teh 300RWHP range.

Thanks for all the responses guys, I'm about 6' 185lbs, the passenger is probably 5,7" 160lbs, I had a few cases of beer, sleeping bag, two big tents a bag with clothes and thats about it, I'm kinda worried somethings wrong with my car I thought I would pull pretty hard on him but didn't. The car seems fine, I'm hoping he just had a bad *** car because he wouldn't tell me anything that was done to it, just a "You'll be faster" at the beginning of the race and a "See I told you" at the end, then he got off on the next exit. I'm going to head to the local 1/8th tonight to get some runs in and see where I'm at (first time to the track woohoo!).

The fastest I've been in my Z28 was 141. Windows down, T-tops off. I had no problems whatsoever. However, the guy I had with me is about as fat as me.
I've said this elsewhere, but I will restate it: Fat people must make your car more stable.

100rwhp from a PI swap with full bolt-ons? Links, please? I've owned 2 GTs and spend plenty of time on the Corral/Stangnet/etc and most guys make 40-50rwhp with the swap and tune. So you can get 50-60rwhp from bolt-ons? Are we talking porting/polishing/cams? I'm not trying to be an ***, but that seems high. Prove me wrong, tho, I haven't been in the Ford camp for a while...

99RebelZ28

If I had a gt I would definitely be saving up for a supercharger because a bolt on gt still gets beat by a stock ls1. My buddy had full bolt ons plus cams and he still only made 282 rwhp although it was on a mustang dyno....but still. He would be at my rear bumper up until about 110 where we usually shut down. He had 3.73s and nittos, so he would get my off the line but I always caught him.
btw this is when my car had a catback and the k&n fipk
