1) Ported throttle body on a cam'd car?
2) Larger MAF ends?
or
3) SLP's MAF (or any other brand for that matter)
4) BPP swears their powerduct + coupler adds 3-5 hp.

I already have some of the more "proven" add ons, ls6 intake manifold, air intake/filter, headers.

Any other "cheap" mod's to add a few ponies (cheap being hundreds of dollars, not thousands)

As some of my previous threads have said, I think I am going to just CAM my car out instead of the S/C or head/cam route, but I haven't fully decided that either.

1) Ported throttle body on a cam'd car? - Yes, 4-8 rwhp

2) Larger MAF ends? - Same effect as leaning out air/fuel ratio (tuning)

3) SLP's MAF (or any other brand for that matter)- Same effect as leaning out air/fuel ratio (tuning)

4) BPP swears their powerduct + coupler adds 3-5 hp. - possible on a heads/cam car

 

So your saying if your already tuned #2/3 is a waste of money? There is no extra airflow provided? They are rated higher CFM, but I guess something else is restricting or something?

I would not bet on any of those mods to "net" any RWHP..

Just my opinion as I have owned all of those at one point on my 99 A4 and my Z06.. :seeya

 

:iagree:

 

Exactly :yesnod:

 

Been there with BPP. HP claims are biased to depict the absolute maximum HP possible under unrealistic setups that will never exist in all but the most extreme circumstances. If you read the BPP doc on the power duct for example, BPP claims that you will get $$ HP with the power duct and even more HP from the forced air effect of air speed. I asked Ernie if he got his reported HP from the dyno, and he answered that he interpreted HP from 1/4 times. Funny that all OEM vendors play the shell game with HP numbers.

I installed BPP's Vortex Ram Air, power duct, x-pipe and Corsa Indy pro and I lost 1 HP on the Dyno, even after 2 months to let the Puter learn the new set-up. Ernie tried talking me into cutting the wiring harness to install a MAF Translator to ritchen it up and make the other bolt-ons work. I declined. Installed a GMAF (cold air) in an attempt to compensate for +10 LTFTs. Ended up going to an LS1 tuner (Force Fed Performance). He suggested a cooler thermostat, throttle body colland bypass kit and a new Fuel filter. But the first thing he did was to prove to me that the GMAF was more than a waste of money, it held the car back. I drove out with a consistent 350 at the rear wheels.

Find a good tuner!
:party:

 

I should have 500 rwhp if i added up all the claimed numbers for mods done to my H/C car. I'll beleive 8rwhp for a ported throttle body and 5hp for an air bridge when I see a before and after dyno with nothing else done and for that matter...who doesn't have different results in 2 consecutive pulls anyway.

 

You are probably better off with a good LS1 Edit tune and pull the screen on the stock MAF...Just my 02.:D

 

On a slight side note about dyno #'s not being consistent, I have found that superflow's dyno is VERY accurate. I did 4 pull's on them and they are all within 1 HP. Absolutely amazing. After talking to the owner, I have a new respect for the Superflow and a lot less respect for the dynojet's. Superflow dyno's cost 100,000$+, while the dynojets 248c is like 40,000$. It's like anything else I guess. You get what you pay for.

:iagree: also.
