Hey guys, I just bought a 2003 Mach 1 with couple bolt ons, off road X, frpp 4.10s, Bama tune, short shifter, anyways my question is will these car run high 12s with bolt ons and good launch? I'm fairly certain I can squeeze a high 12 pass out of it but I work at import dealer and all my subie buddies are saying no way blah blah cuz they all have a turbo subaru. I've been there, done that came back to mod motor. Anyways you guys ever squeeze 12s out of a 4v NA car? I have a hurt 2nd gear which I'll be pulling and rebuilding hopefully next few weeks but I'm gunning for 12s before future mods or boost, thoughts?
2003-2004 Mach 1 or Cobra 4v 1/4 times?

12 with your mods are possible on street tires. A better tire and full weight can be in the 12.40 range.
Yeah you should be close now a good tire will put you in mid 12's easy.
My good friend had an 03 mach. Similar setup to yours and ran on 275/50/15 mickey dr's. His best was 12.4x. He later had an 01 cobra with a solid axle and mid lengths. That car, on the same wheel and tire, went 12.18. Those are full weight passes with a 225lb driver. He went in the 12.8x-13.0x range on regular radials. He now has an '06 GT with longtubes and a 4.10. It has been 12.7x's.

My 04 Mach swapped 5spd convertible with full exhaust, 4.30's, RAI, tune, and shifter on street tires went 12.8 @ 108mph with a 2.0 60ft with staggered bullitts and 315 nitto street tires. Put a 315 drag radial on it and went 12.7 with a 1.7 60ft which is crazy but its crazy how that happened but it was driving mostly and 2 different days. I put 15" drag wheels with 275/50 drag radials and went 12.50 with a 1.8 60'.
I had Comp 106100 cams and a ported stock length intake installed and had the car tuned making 348rwhp/324rwtq and was having injector issues but managed a 12.2 @ 112mph with a 1.8 60'. The car was full weight nothing taken out either.

Info on my mods back when I was NA running 12's and 11's..... http://www.svtperformance.com/forums/showthread.php?985500-The-Evolution-of-my-99-Cobra&highlight=
Well mine is having some pretty nasty synchro issues with 2nd and 3rd gear. Guess it's time to pull the trans and rebuild it. I'm hoping to be running 12s before fall. Thanks for sharing guys. Any tips on tranny fixes for the tr3650, shifts fine under normal driving but at higher rpm grinds pretty bad. Def can't 1-2 shift fast or hard. I don't want to get hosed by local trans shop. Probably should throw in a new clutch while it's out.
I mean..i went 13.0 in a bolt on 2v so I don't see why u shouldn't go into the 12s as u are now lol.
Well after this post I pulled my trans. It's a the shop now being built. I also installed some goodies while it's on the hoist. Full kyb suspension, JLT ria, McLeod clutch, Stewart high flow water pump and t stat, new brakes, shifter knob, and I'm going to pull the trigger on some sticky mickeys. I damn sure better be in the high 12s or I'll be upset. My driver mod is pretty solid lol
Sounds like you're well on your way to running in the 12s. I love how hard the mach's pull with such basic mods. I still wouldn't mind owning one.
Good luck op. Should be easy.
What are the dates you will most likely go?
Track, location and weather depend a LOT! None of you guys would run anywhere near those track times here.
