Is there a big difference in HP off the line. Looking to improve times at the track and was wondering with the hot temp we have right now if the cold air rammer would be a better mod. I have the blackwing know with cold air screens and my 1/4 mile is in my sig. Would I gain anything from this switch.

 

any one on this please ?

 

I don't think it will make a substantial difference, maybe a few HP at best if any.. I have the Blackwing on my car and like it.

So no real differance. I hope someone can put some times with both intakes installed.

 

Any people with times on the vortex and the blackwing, trying to determine if switch to vortex will help my 1/4 mile times

 

I guess I am talking to myself :crazy:. With all the BW and Vortex systems in this forum I would hope I could get some help please. Thanks

If not I guess I will go for a nice cold :cheers: :D

 

If you want to go 12's get a vortex ........if not get a blackwing......

PERIOD........

Vortex, 6 speed, XR-1 and crappy 60 foots of 2.14 = 12.78 12.80's all day long.

:seeya

 

not sure I could get there with the 2.73 gears that I have. I have 3.42 to put in but I was wondering what the difference in HP is without the 1/4 mile times.

If there is a big difference then I will switch but if it is something like 5 HP and less than a 1/10 of a second in the 1/ mile then I would stay were I am at.

 

Cold air makes as big a difference as the filter... for example one member with a blackwing was running .15 sec faster than stock in the 1/4. They added a Cold Air Box to the Donaldson and picked up another .15, so they where then at .3 sec faster than stock. You could just get a CA Box too, or sell your Donaldson and get a Vortex, cost and results would be about the same either way.

BTW, you don't get to may replys to topics like this, b/c the same topic is usually posted about 2-3 times per week. You may want to do a Search if you want more inputs.

Your right on the topic. But I was hoping for some dyno number to compare since I already have the donaldson. I would buy the cover but afraid of surging on the car.

 

golfman,
Dyno numbers :confused: Typically the car is dynoed with the hood up! The vortex and all other bottom breathers are sucking air off the garage floor...hopefully they have a fan running. You wont find your answer from dyno numbers :nonod:

I have personally used in the following order...Donaldson...Donaldson with cold air cover...Vortex...Halltech bottom breather. I got 14-16hp gains over stock on all four combinations. Prices ranging from a $225.00 to $550.00. You could say they yielded identical performance on the dyno...keeping tolerances in mind.

Track times were consistently .3 better than stock. The Donaldson without cold air ran the same times as the Halltech. So much for the ram air effect!:nonod:

I am currently running the Donaldson without cold air or cold air screens. I am pleased. I like the access and the guage that tells me its time for a cleaning.

I spoke with one of the MTI guru, regarding going back to Donaldson from the Vortex...we both felt that the additional filter surface area and the quality of the media on the Donaldson offset any cold air gains and "Ram Air" from the smaller filtered Vortex.

The track has proven this to be true when I was running 313 hp/317 tq and now that I have 408hp/394tq.

All testing was done with the MAF screen removed.

I know how much the forum loves "Cold Air" and "Ram Effect" so flame away!

Just one question...How many of you have both Track, Dyno and experience with all three systems?


Now next time do a complete archive search so I dont have to come back here again :D :lol: :lol: :lol:

Thanks for that information. That was and excellant explanation. I will stick with my blackwing doesnt seem like there is anything better out there.

THanks AGain Adman
:) :cheers:

 

I dont have any "numbers" that you are looking for, but I did have the Blackwing on my car for about 6 months, and thought the Vortex would be better, so I sold the Blackwing,and installed the Vortex, and can't tell a difference at all! :nonod: I would keep the Blackwing, looks better! :yesnod:
