Well there has been ongoing races between me and this guy in town with a Mach 1. I raced him when he was stock and beat him a couple of car links.....then he went and put on a chip, some pulleys, exhaust, and maybe a couple more minor things. We raced again....and I won by a nose. Both of those races were on stock tires (for both of us). Then we both ran again, same mods & we both had drag radials....first run....he won by a nose...second race...he won by a car link. Keep in mind...it was HOT! Well I have now just recently put on Kooks long tube headers with high flow cats. He would not run this wk-end....told me he wants me to wait till he gets his gears (4.10) and x-pipe on his car...(little bit scared he knew he would lose i guess). But anyway....Who do you guys think will win the next race....they say gears and exhaust make quite the difference on Mach 1's....will just my LT's and high flows be able to put me over the top? Also, keep in mind...all the races so far...I pulled him off the line and he comes back quick after about 80 and either catches up or passes me by just a bit. All opinions are welcome here....I really would like to beat this guy!! Thanks!

 

Good luck... I've seen bone stock Mach 1's run sub 13.0's (perfect driver)

Unless it's nice and cool out (below 70deg), you may have to hope for a bad shift on his part, or not getting any traction with the 4:10's. He'll probably have ya one way or another by the end of a 1/4mile.

With all my current work, and the best tune I've had - I ran a 13.05 @ ~105mph (1.93 60'). This was with ambient temps at 85deg. Also ran a 13.08 @ ~104.5 with a slower 60' at 79deg. All this on F1's.


Current work include:
Apten Eaton
4# lower
SCT tuning
JLP 12" filter/ram air
160* stat
No hitch/spare

 

Well I run consistant 13.0's any time. My best time was a 12.87 and that was in 80 temp. All of my times were before I installed LT"s and high flow cats. Do you really think that Mach is running that much faster than that?? Also, How much should the the LT's help me out??

 

Long tubes give you sound.

That's about it. High HP engines can see some gains, but you won't see anything like the gains he'll get.

You'll probably lose.

Please tell me you aren't serious???? Cause if you are, you are wrong. On a stock truck alone, headers combined with the high flows have shown over 10 rwhp and 20 ftlbs of torque. A good bang for the buck???........depends on what you value. You are getting a sound increase, but a performance increase as well.

On trucks running higher boost, gains have been seen from 15hp and 25 ftlbs and up.


Anyhow, yes, the gears on the Mach1's make a BIG difference. The latest HOT ROD magazine did some testing in one of the last issues I read. Same issure where they said the lightning ran a 14.2 @ 98 mph against the SRT10

 

Well I am not running a ton of boost, but more than stock for sure. I have 6lb lower (used to have 4 before lt's) and cold air and chip. Probably running 13-14lbs or so! More opinions!

 

I dunno my friend has a pretty well hooked up Mach, w/ just about all the bolt on's save a blower, turbo or nitrous including 4.30gears. A big difference believe it or not is if his is an automatic or 5speed. According to my friend the stick comes with about 10more HP and better transmission gearing. Driver plays a bit of a difference too cuz his car went 12.70 with him driving, and when another friend of ours (he like a professional or something) the car went 12.45. If you really wanna win, put the 4# back on, and hit it with a 50-75shot and a new chip tune.

Other options would try to increase your cooling effiency by adding things like a Better Heat Exchanger, Power Cooler, and phenolic spacer. This way you hopefully dont lose as much power from the heat.

Good Luck

Yes I am serious. I own the Kooks long tubes. I like them.

Did they get me $1000 worth of HP? nope

Did they get me even a tenth in the quarter mile? nope

Will they help me down low for a street launch? nope

So I stick with my statement that if they were basically even and he added long tubes and the Mach1 did full exhaust, the Mach1 will win.

Coldie

 

do you have high flow cats with them??

Headers going intot he stock exhaust won't show much gains. I think maybe expecting a grand worth of hp is too much.

As far as no gains..........you got me. They may tend to richen your a/f mixture so maybe that's why you show nothing.

What was your before and after dyno numbers???

 

So none of you guys think I can win? I was actually expecting it to be a very close race...

 

Yes I have high flow cats (silver bullet all the way back).

The long tubes and exhaust got me around 10hp. out of 450hp, I count that as virtually no gain, expecially for over $1000.

All I was trying to say is his long tubes aren't going to help him in this case.

 

MM&FF pulled a 13.2 with a stock Mach 1. The manuals have more power than the auto's and if he puts in a 4.10 you are toast

 

I dont think thats right either
you need to flow out all that boost you are pushing in
so if your running a 6# lower with stock manifolds your probably
losing 20-25hp and 10-15 ft # tq easy on the dyno

Hell my Bassani mid-lenghts added 18/12 to the wheels with a 4# pulley

but i would still get the cooling parts especialy if you live in the southern part of the US (heat kills L performance)

just my opinon

as for the mach 1 MMFF tested a stock 5-speed against a GTO
and it ran a 13.51 at like 103
so anythings possible especialy if he cant drive

Good luck

 

Hell I had about the same mods as you (way back when) and I ran 12.3s all day long. Check out your tune ......you should be faster than that.

 

My 12.87 was in 80 degree heat. I have not been back to the track since I put on the LT's and high flow cats but you guys are now telling me that after I spent $1300 from JDM that I dont have a power increase. So maybe I am no better off....
