Beretta 2017 Autocross Spec D-prepared

[Amateur]

Thank you for making this a beretta again, i last looked at this post when it was a Saturn

yeah don't mention it. I think we can all say that it looks better as a beretta!

UPDATES;
my stock air filter was dirty. So i bought a new one that's reusable and washable.Here's the result




obviously I did this for aesthetics, convenience, and a meatier sound at higher rpms

Nice looking intake

No K&N?
Hey have you seen these? http://www.rodneydickman.com/ZeroLashEndLinks.html
Not sure if he makes some that fit our cars.

No K&N, but whatever came in the kit. The filter provided quote on quote "The SW1 Air filter features a tuned velocity stack to increase velocity and decrease turbulence" along with the madrel doohicky, "The concept is to create two different air velocity profiles, one traveling at higher speeds than the other"
i guess some science went into this thing to make it all flashy but lets face the facts here. This concept might work wonders on, let's say a bugatti veyron where it sucks in an enormous amount of air very rapidly for its 16 cylinders, BUT on my car, it's in vain as my engine is too small and the compression of the cylinders are pitiful------> (9:1)! for this witchcraftery to do its thing.



those endlinks look pretty sweet to get a nice snug fit with the swaybar. They look pretty similar too! i wouldn't mind buying a set to try them out to see if they work with the retta after i buy a bigger front sway bar that is.
As with any beretta on here, they are built up piece by piece taking years and a surprising amount of money to make their own.

I kind of fail to see the point.....it all meets at the TB anyway. I'll have to look into it some more. Seems to me that it would screw up the flow unless you are at WOT.
I would think that the throttle response would be a little sluggish in normal driving.

On those end links I'd just use them on race day.

I'm sure I already told you, but....
I had a nice gain when I put a light weight alternator pulley on my Ecotec. The stock one was about twice the weight of my CS130 on the Beretta though. The one that I put on the Beretta didn't give me much help. It was from MP Racing the MRZ could have less weight(not too sure about that). If you get one make sure it's the stock size and not overdrive. Also you will need an impact and a small puller to get the old one off.

[Koots]

That is a nice looking intake, did you buy that or make it yourself?

I'm not sure If I missed that or not LOL

Not finished my car yet, but I'm still using the stock intake. Our engines might not need a full cold air intake, but the stock intake is not exactly the most ideal either.

to be honest, it's all the same, these intakes literally do next to nothing on a motor like this. Their real potential comes out when forced induction is involved/ high compression is involved.

wow, you are full of little tid bits of info! I see where your coming from but as you already mentioned, the one for your 'retta didn't do much. If i really wanted to free up some hp, i could remove the air conditioning but I'm not that crazy about it....i like to keep this car civilized.

Nope, definitely bought it. It was supposed to be a plug and play but it wasn't perfect. I had to buy a bigger coupler for the throttle body and a smaller grommet to plug in the sensor. I don't see a problem with the stock airbox at all. I put this on for the convenience of a simpler filter design that's rewashable and a better sound to the engine. I've driven all kinds of engines, but in the end, i think pushrods sound the best.

[Money pit Beretta]

I'm sure the Beretta would have responded better to the weight of the Eco pulley. But that was 5 rib vs 4 rib. Also it may be 4 cylinder vs 6 too. One more thing, I had a reman alt with a cad plated pulley. The OEM pulley may have more weight.

LOL sounds like you would have been better off with an intake that didn't have that extra part in it. Sounds like it just added a restriction, something you don't need with the small amount of air that you are pulling.

Koots the gains on a WAI vs a CAI are very close. The only change is where you get the most out of the intake. CAI is more for low end and WAI is for top end.
I have tested both on my 3100 and found the CAI to be better for DD. I already knew that, but I had the chance to try to see if the engine responded better to one or the other. The good thing about a CAI is you can always make it into a WAI later.
Length is the key to tuning an intake. Any length can be used, but there is a sweet spot(for low or top end, which ever you are shooting for). Too long and you kill off the top end, too short and the low end is lost.
I wish my 95 had the washer/coolant tank combo. Then I could test lengths to see what is best. My 90GT's CAI went all the way to the bumper, the 3100 stops in front of the wheel well(because of the washer tank).

[Koots]

I had both on my old Civic too, but I tested them when I was still using the pitiful Non-VTEC intake manifold and TB. Once I swapped to a ported VTEC manifold, I was pulling more air at all RPMs and all those intake testing would have made a bigger difference.

That stupid car was pretty useless until then. That was the final piece in the puzzle to getting decent performance out of that engine...without digging into internals.

[Money pit Beretta]

Oops forgot about the Civic build. Sorry for the review. Guess I just wanted to talk about intakes.

[Koots]

Intakes are wonderful to talk about. I have some experience with it, but I didn't get to see much of a difference because of the choked down intake manifold I had on that Civic.

I'm planning on rigging up something but also modifying my stock intake to optimize it too and run both back to back. Then I plan on running a 98+ IM and the IM adapter from IPP, so I can actually swap to a bigger TB. Then I will get some good data for all the 2.2 owners out there...without having to sift through BS like on the popular J-body forums.

[Money pit Beretta]

Thank you for your understanding.

Sounds like a good plan on the 98 intake, keep me up to date Koots. Yeah the J-Body forums are almost useless because they just seem to put people down.

Well, The deed is done! I finally got around to ordering that Wilwood 12.19" front brake kit.
I went for the red caliper upgrade and stayed with normal un-drilled brakes.
It's no surprise that our stock brakes are less than stellar when it comes to hard driving....brake fade comes at you quick and I hate that so much!
Now I was thinking about going for the Baer brakes on sale in the forums (at that price, it's a steal), but they are gigantic! requiring a 17" rim....too big for my car's purpose.
Now I know front offset is affected by this kit, so I may need a small spacer to keep everything "copasetic"
I also need to buy brake lines separately for it and so I have a question; are the Jbody brake lines the same ones on the 'retta? if so, then i can just buy the ones meant for this kit.....if not, then I'm sure I'll figure it out.
