Ok I am putting on all my Mods. Just what can I expect. I've read all the claims but just what is the truth? Putting on MREV 2, 5/16 ISO Copper spacer, JWT Popcharger,chrome Ztube,Fast Intentions Exhaust and Test pipes. All the claims add up to 43 RWHP on the low side. BS or not? Also I need input on the best RPMs to shift at if I was going for it! Any input will be welcome Thanx

 

Expect more like 20 to 25. Unfortunately you can't just add up all the claims that manufacturers make.

the chrome z tube should net approx. 5 whp more than the regular z tube.

 

how so?

 

because its just cooler...duh

 

lol...

 

...internet sarcasm... so hard to spot

 

You should get the pulley sets too After that you'll have on the bolt ons for the NA mods, besides that I had about everything you had with pulleys and I only had 254whp 247tq when I was NA, I suggest you do all that and then get a ecu-reflash (osiris uprev!), you'll be very happy with the performance gains.

 

all those mods will yield about 10 peak HP and little bit midrange jump. With a dyno tune expect another 20-30 hp and nice midrange gain.

 

Hard to believe just 10 HP for $2800. I'll send it all back if that were the case.I thought the ECU on the 06 was capable of reseting and learning for the mods. What is Osiris and how much $$ is that? I hope someone on here will just help me out and answer my original questions also.

 

i did all those NA mods and never once felt the money was justified via butt-dyno. but we all know louder= faster.

People on here say they can feel 5-10 hp difference, i sure cant

 

You can't just add up manufacturer's claims of power gains and add it up and come up with a total expected gain. That's called ricer math.

When you combine all those bolt-ons, some things may negate others and you really never know how everything works out until its completed and tested.

If you get full bolt-ons, my suggestion would be that the tune would be the most important part in maximizing your gains.

It is hard to believe then i suggest u don't spend $2800. That is the type of car we have. U can take ur car to a professional tuner and with osiris they can extract more power from a BONE stock car than all the mods u mentioned.

My car is making its peak horsepower at 6200 rpm, I found out that shifting at 6600 rpm on the tachometer will give me the best results at the track, U will see a lot of people arguing this fact but those people most likely havent tried shifting at 6600 rpm and compare those times to shifting at 7300 rpm on the tach.
