Is it correct to assume that bold on parts are NOT additive in HP gains?

Example 5hp + 3hp does not equal 8hp

So how much TOTAL REAL dyno'd HP can be gained with these components?

- Plenum
- Headers
- Mufflers
- Cold Air Kit - Not sure if this works with Plenum
- Spark Plugs -
- Spark Plug wires -
- Air filter - K & N
- chiptuning -
- Others?

All MODS have to pass emission tests!!

Tall order!

 

On an NA car you would be lucky to see 20-25hp from those mods.

 

I can show you any gain you want on a dyno. If you want a graph for your glove box showing another 200 rwhp gain, let me know. If you are serious about power gain, don't measure it on a dyno, but measure the performance gains based on where and how you drive. Beleive it or not, you can actually lower your maximum hp and if you shift the power to a lower point in the band, your car will perform better.

Short of increasing fuel and air to the engine and/or pushing the timing more advanced, their is little you do to an NA egine to gain substantially in power.

You cars performance has more to do with power band, gearing, weight, etc, than it does with peak hp.

 

I would save my money...if you REALLY want more power, get a supercharger....

 

yeah, if you want serious power, get a sc

 

hey if you can turn off the awd like the vw/audi tt haldex systems your more than welcome to use my dyno in mass hell if your house has 220v ill bring it there and try to sell you one.

 

The super charger is about 12 grand!! I guess I will just enjoy it like it is and then buy a TURBO!

 

yes but you can be faster than a stock TT with a supercharger....but do enjoy it as you will probably find its a very capable 320 hp car.....I mean its a 177mph car, what more do you need?
