When I said "simple" I meant pullies,gears, exhaust, K&N filter and timing bumped to 14*
No induction or valve train changes.
You can include gutted interior but I don't think that's necessary for 13's


BOSSMAN....I'm right there with you doing things in the dirt.

MD, I consider gear changes simple because you can take a car to a shop and have them do it for you for about $500...or...do it the hard way and swap rears in your driveway which can be done in a weekend.

Anyone else wanna say it can't be done?

Its very possible, Im in 13's and basically have all bolt ons, prett much every bolt on except upper/lower intake.But with Headers, H-pipe, FLows, Gears 3.55,subframes, timing 14*. youll be in 13's, my friends 91 Notch went high 13's with those bolt ons, on stock tires n' everything stock except what I listed.

we always kept stock headers with the stock heads. 1 5/8 headers slowed one of "our" first cars down, so we never used aftermarket headers in all our stock 13 sec mustangs

Im havin a tough time believin the 103+ trap speed outta just an extra 20 or 30 hp

As far as "SIMPLE" bolt-ons, well I suppose that depends on what you compare it to. I can swap gears in 2 hours, a cam in 3 hours... may be a bolt-on but its not whats considered "simple".

The mods slo93 posted are simple mods, and certainly running 13.'s with bolt-ons is impressive. Cutting a 1.9 60' of stock tires is impressive - definately takes driver skill to do that - but - driver skill isn't gonna get you a 103+ mph trap speed - thats all about hp to weight ratio and your trapping faster than cars with twice the mods... 50 more hp... interesting to say the least

That's about the only thing I'll agree with you on so far. 103+ trap speeds are usually seen with 12 sec cars.

Uh ive seen a camaro that trapped at 105 and only ran 13.8....just because he has high trap speed doesnt mean hes in the 12, hes far from 12's.

mdvaldosta

no but trap speed is an indicator of horsepower - I've seen cars run 13.5 and trap at 110, really depends on the 60'. A large part of the 1/4 time is traction, probably just as important as hp. A set of tires can knock off a full second or more on some cars. Add gears and traction and you've got a 1/4 killer - so simply looking at an E.T. will show you NOTHING about its horsepower. Trap speed is the real indicator of power, trap speed is largely independant of driver skill and traction - and the claimed trap speed is what looks fishy. I can believe a phenominal 1.9 60', and the trap speed matches what would be expected of a 13.6 car with a 1.9 60'... the problem is I don't beleive the trap speed, which is why I don't believe the time (with just those mods listed that aren't worth but around 25 hp).

Once again, I beleive its very likely that you could run 13's in a 5.0 with just bolt-ons... but not a cat-back, h-pipe, and pulleys... I believe, with my experience, that it will take soem sort of sticky tire and gears to do it. A 1.9 60' is about whats to be expected with drag radials on a stock 5.0 - so add some gears and some bolt-on's and your there - but at a trap speed of maybe 97 - 98 mph ON A GOOD NIGHT. to pickup 5+ mph would take probably another 40 hp.

hey,MD what about a 108 trap? is that 12.3 territory?
my dad's 89 lx hatch is bone stock except for a h-pipe,and glass packs.(don't ask)
i vote to make his car a guinnie pig.................

If you know what your doing well enough a Supercharger is a "simple bolt on". I think if you buy a 5.0 just for what most think of as "simple bolt ons", I'd say you bought the wrong car. For as cheap as you can get a 5.0, H/C/I or a S/C arent that far out of reach.
