Here Is a List of the Best mod's for under, and their Prices
**Bolt Ons**
Intake Spacer $100 (roy M1R#)
Catback $300
X-pipe $300
CAI $200
MGW $169
Aluminum DS $200
Accufab TB $350
L/T's * $400-700
Gears *

**Tuners**
Diablo Predator $319
SCT SF3/X3 $479



thats a list of all the mod's i could find to be fairly inexpensive and show some results on a dyno/ street, and that can be installed with average joe tools and in average joe time. with the singular exception being the long tube headers, from what i understand they're a bitch.

*= prices vary depending on maker.

# For all you guy's that are looking at getting Intake spacer (which i recommend) RoyC on here is the man to get it from. He will help you in every way possible, any questions and concerns you have he can help and will be more than willing to help. After receiving a bunch of PMs from Macher's and Non Mach 1 owners i thought it would be a good idea to get his contact info.

Any kind of spacer you need from 3/8-3" this is the man!

Excuse my ignorance, but what effect does the intake spacer have on performance?

 

I've been trying to figure that out too. My guess (and it really is a guess) is that it reduces resriction in the intake manifold in some way. Porting makes sense because it is the process of removing any burrs or castings that may impede airflow, but the spacer doesn't really do that. Maybe it allows more air to be in the intake at a given time?

 

this is going to be a very very rough explaination, but here it goes.
the intake on the mach is kinda crunched real close to the engine, and when the air goes in, it's really tight, and "restricted". So the intake spacer add's a gap so more air/ more cool air can flow in easier and thus becoming less of a restriction on the engine, and forcing the better air in allows for more hp/ tq to be achieved.... and it gives you better power thoughout the power band, so even though your peak gains aren't much, 4-7hp and 15-20 ftlb, this is an increase in the WHOLE rpm range.

wow i really butchered this with my limited understanding, but thats the kinda sorta way it works and what it does.

 

Makes sense to me.

 

The biggest difference with the space is torque. It only makes about 5hp, but the torque gains are much higher.

 

also, with a spacer there is a larger volume of air for the induction system to pull from, so when the injector pulse is mixed with the air coursing down the intake ports, there is also a slightly greater velocity to the charge. That's another part of the help

 

Can anyone recommend a place to buy one from? Also, do they come in different sizes, and if so, is there an optimal size?

Thanks

 

yes, there are any size you want, Roy on here just made a 3" one. he has advised me that a 3/8" spacer is optimal for the machs, and you want the largest one possible for the cobra.

 

PM RoyC. Says he's a newb - he ain't. He CNC's them himself. 3/8" is best unless you want to muck with your EGR. (like, eliminate it.)
