BDJ's Racing,

I was not challenging you. I was only trying to clear up why HDDP is such a pr!ck when it comes to this stuff.

I believe that all of my posts have been neutral.

If you have the dyno done and gain 15 more whp than stock, then that is a wonderful accomplishment and I'm sure you will get quite a few orders.

I will not pay for any CAI system right now, regardless of it's claims. My car is bone stock except for the brake fluid, wheels and tires. For the track, it goes up to Rotors and Pads too. (Okay, minor cosmetics stuff too... )

I'm not interested in top speed at this point or raw acceleration. Mostly I'm interested in improving my technique on the track. When I get to a point where I "NEED" the acceleration, then I'll look at an ECU tune, Overdrive Pulley set, Intercooler system upgrade and THEN a more open intake, possibly an SL55 setup, but I'm not sure yet as that is a long way off and will probably be proceeded by some suspension tuning.

I wish you luck with your products and hope they will benifit the Crossfire community.

Cheers!

 

It is on Needwings website located here.

 

Well MMZ, my bad. Well I have been wanting to dyno my car for a while now, and i just started a new thread about it. So I hope it turns out good for everybody!!

 

No worries... Just wanted to make sure I was not mis-understood... it happens so often you know...

 

YUP... No truer words have been posted... It's called TOUGH LOVE ... LOL

MMZ is one of the most level headed people on this forum... He would never pass judgement on anyone... Me, on the other hand... give all the NOOBS grief... Especially when it comes to mods...

VROOM VROOM... I have some snake oil for sale, it comes in a really nice bottle...

 

lol is this the same snack oil salesman from the other crossfire site ? I see it is the same IP ADDRESS ?? I have bought 3 bottles and am yet to receive them.. DO NOT BUY FROM THIS SALESMAN lol he is a scammer

 

What did you buy? The Eneos oil? And they never shipped? Damn - they look legit. I'm going to stick with Mobil One anyway.

YIKES, YOU MEAN AN INTERNET SCAMMER ? WOW... HOW DISHEARTENING AND YOU SAID HE WAS ON THE OTHER CROSSFIRE FORUM ? I HOPE HE DOESN'T MIGRATE OVER HERE...

 

hahaha, they should call it anus oil! cause you gonna get, effed! if you like paying big $ for oil, stick with MOTUL

 

NOW, BACK ON THE TOPIC... CAI's

So what is the design process for this one ? is it just BIGGER IS BETTER ? In my humble opinion, colder is better... what are the calcs for temperature of air vs density ? SCRATCHING MY HEAD...

Can anyone who is building a new CAI for the SRT6 please provide the IAT data from the sensor... I don't care about dyno runs... I want to see the IAT temps...

 

I think the CAI is a well beaten horse, let's move our efforts onto full blow ported heads, screw this CAI crap, where are the aftermarket suppliers damit!

WOW - this is the second time this month a bunch of losers have ruined this forum.

What a shame.

I really want to hear about this... Please tell us all about it... specs would be required and your entire process including how you rebuilt the butterfly valve and DBW motor attachment. So what's the throat size now ?

 

It is just fully ported and polished, and the shaft has been narrowed. I will be offering this to anybody on here for $150 plus shipping, from them to me and me shipping it back to them. Turn around time is the same day, in most cases.

I have saw as much as 12 whp on a 1.8L Acura engine in a civic. The car made 146whp, then with P&P, 158whp. No other mods. I have did around 400 P&P on Throttle Bodies now. Still not 1 complaint yet.

I do not change the butterfly or motors. Just removing tons of unneeded material and narrowing the shaft, and then polish it all up on the inside. This process works on N/A motors, super charged, turboed, and even NOS cars.

 

So what you are saying is that you are porting "enlarging" the throat of the throttle body but you are keeping the butterfly valve the same diameter ? that would leave an air gap that would cause a very LEAN situation during idle and the car would sputter and stall...

What is the throat diameter you have increased the TB to ? And what diameter have you reduced the butterfly shaft to ? Does that mean you have replaced the actuator motor to machine the butterfly shaft since they are integratedand pressed on at the factory ? Also, how do you secure the butterfly valve to the shaft now that you have reduced it's diameter ? the retaining screw taps have very little material on either side...

This is good information... Thanks for sharing...

 

hey sounds cool, I'm interested after the guinee pigs work out the bugs!

anychance you can modify the butterfly blade ratio, so that it tips in earlier than stock? if so this might be a great fix for the throttle lag.
