Average HP Gains (?30HP?)
 

From the 3 items on a 88 MK3 Turbo A/T.. What HP gains you think I will see?

Air filter system - BLITZ LM Intake System
Down pipe - Megan Racing 3in
Exhaust system - Custom 3in W/Dual 3in Muffler

I was thinking it would bring me from 230 to 260.

10hp for the filter system
5hp from the down pipe
15hp from the exhaust system
30HP gain

What you think.? :uh:

think you need to build a heat shield around that air filter. or you might see hp loss.

GREAT IDEA!! I was just going to make a plastic box.. however, heat shield box?? what do you think?? What type of metal is easily available, affordable and works great as a heat shield?

I looked for the answer but no find? Anyone know if one of them LONG cone filters are any better than the average size one like the one I have listed above? I seen the long ones in the part store... Was just wondering..

You can use a small, rectangular plastic trash can to make the heat sheild for the filster with. Just cut it so that teh plastic will cover any side taht might be expsed to hot air form the engine. Hope that helps.

If you take your time you can use a dremel and a drill to make a nice one out of aluminum. Just use posterboard to make up a template first. I used rubber hose and zip ties to make guards for the edges. Although mine is for a 7mge, it can be done for a 7mgte.

Wow, dude.. Love it!

At the wheels or at the crank? In either case I'd say your estimates may be close or just a little over optimistic. What mods do you currently have that put you at 230 and how was that measured?

The stock intake isn't THAT restrictive and close to stock engines see little improvement.... running a crap filter in the stock box... now that's another story. Once you get into the mid 300's the box has gotta go or be modded appropriately.

Well, closer to crank.. You know me.. Mr.Optimistic.. What would you say would be a better estimate of the parts I listed above in HP gain?

another idea if you dont want a box in your engine bay, just route a pipe down under the headlight behind the fog light near the road. fresh cold clean air and a non cluttered engine bay..
