Hey, I'm really getting tired of the crappy old Mass Air Flow Sensor so right now I'm just ready to convert it to Speed Density. Altho I dont know how to do it myself or how much it would cost, so I was wondering if anyone near by me would be willing to help me do it and tell me how much i'd be spending I would really appreciate it

 

Tired of the *crappy old MAF system*


And what ETs are you running, I wouldn't call the system crappy first its probably most likely something else that is the problem.

You need to go to the DIY section, and read the frist sticky I think it is, then tell me if you want to switch, or better yet if you think still that your crappy system is the reason for your frustration.

I guess out of politness I should ask why you want to convert over.....

 

Well nothings really wrong with the car, i just fixed everthing from when i bought it. well cept the rotor needs to be turned cause it sounds like i'm communicating with Whales but anyway. I would just rather go speed density for tuning purposes, feel limited with the MAF

 

dont know yet

 

By all means you need to read those posts I descibed.

You are not limited performance wise one bit with the MAF system. Take a look at my ETs and MPH running though the MAF system.

MAF will tune 1 million times easier, Granted SD has some options that MAF doesn't but the end result is the same.

I will use the analogy I used before. If your goal is to add 2+2, one option is a supercomputer that needs 15 engineers and 3 months to program (SD) or a calculator (MAF) which one are you gonna reach for if getting the answer 4 means running your best ET or not.

Trust me there is no way your car is limited by the MAF system, air wise or any other way what so ever. Before you switch if you do, take the car out for one last ride. From a dead stop run it through the gears at WOT. Then switch over. I will bet you its months before you can do that again without hesitations, and sorts of fun stuff.

If you want to tune, just tune the system you have to optimize that. that is my advice, and some day after the swap you will think back on my offer of advice......CHeers!

 

hmmm alright, i'll just take your word for it and read up like you said. thanks a bunch for the advice

 

Million times?.
Talk about a gross exaggeration.

Odd that ALL the aftermarket ecms, use SD systems.
I've seen exactly One MAF car run an 8 sec ET., and countless MAP cars do it.

Not a rip on MAFs, just stating some facts about the matter.

 

Grumpy do I sense a bit of worry in your rehlm of speed density? You deck of card have been falling quick in the past few days, try to defend what is left.

As for a gross exageration he will probably have a 14 sec car at best if he never had it to a track or any major mods. That is hardly a car to compare to a 8 sec machine.

And since you brought up ETs, what does your engine run with all the master tuning and equipment you test with? Just curious as many others I'm sure are. IMHO any car that is running any sort of boost what so ever, better be well into the 10s. Since my MAF all engine is just boarding that the first time to a track with it. With the horrible MAF system on board. LOL.

Show your card Grumpy.....we're all waiting..

I'm really starting to like your posts....It gives me something to smile about everytime I come to the board. You can alway count on your to the point replies with no sarcasm

Well need a scan of that time slip too, I don't think I need to show mine since I supplies a video, unless of course you insist.

And let me once again point out to the mods how you offer absolutely no help to his question, but just replied to argue with someone elses reply and make them look less credible....

Credibility is in what you do, not what you say you can do....now we are all waiting for that time slip.....surely you have some lying around.........

 

Grumpy's credibility here and elsewhere runs a lot higher than yours dude.

Witness all the cubes your packing running low 11's thru the MAF, versus people like 85mikeTPI running high 11's with only a 355 and SD.

You trashing Bruce is like my neighbor's yapping little Poodle barking at my Chow.

(next comes the barrage o' excuses, I couldn't get traction, yadda yadda yadda)

 

Here comes the calvery.......

While your at it, let see yours too

Its obvious you boys feel a little uneasy.....please by all means bring what you got.

If you go back to my first post here you will see that I was not trash talking anyone, just answering what I thought. Not qouting people and shooting down their thoughts/ideas.

Here it is in the nutshell and incase you haven't got it, this board would be about 100x bigger and better if a few select people were not here, running everyone elses ideas/techniques down at every chance they get. Now if you like I can do a search, on the last say 100 posts from myself and the last 100 posts from some of the people in question....comparing them side by side, I think you will soon see that my intentions here are to let people know what works for me, discuss in an adult manner the differences I have with others opinions, and NOT sit back and try to shoot holes in EVERYONES opinion except theirs. Its a real shame, if you yourself can't see that.

The board here in the last few days has had a good conversation in regards to MAF, people did not agree all the time, but in its probably the most informative, good reading thread since I can remember. Many people have emailed me with the same saying the same exact thing I am. That some people shouldn't even be here. They do nothing, but critisize people and try to get posts shut down that they don't agree with. I wouldn't be surprised if they stooped as low as to email mods about threads they don't agree with to try to get them closed. Why because they feel threatened. By what you might ask, they may be wrong.

Again in my book and many others, credibility is earned and bashing other people ideas/posts continually doesn't get it from me and I'm sure alot of others.

As for when it comes to anything performance oriented, all I am say is credibility is proved where the rubber meets the road, and the reason I asked for the slips.

 

And for that a 355 is nothing to sneeze at....how about Ralph over on the Corvette forum running a stock 350 vette/sr/219 cam with a best of 11.57 and oh yeah he is running a mail order chip, and through MAF. You can see him run regularly at E-town.

If you want to go back and forth we can all night if you like.

 

ggggrrrrlllll

 

Ski, PM me some info on this guy!
I'm running a 355 and I want THOSE kinds of numbers!

 

ragtop,

I assume your talking about Ralphs setup. Its a very common setup he is running with excellant results. I will be the first to admit it runs better than normal. But at any rate he is doing it.

Its a 350 shortblock, with 219 lingenfelter cam, 190 AFR heads, Accell base, and SR plenum. He runs consistantly in the 11.7 range, sometimes cranking off a better ET if conditions are good.

Its a full car(not gutted) and basically everything is optimized to to hilt. That is the key, everything has to be working to the best of its ability. Usually when people are not running as good as they should be, they look for one major item like bad wired, as it could easily be that, it most likely is a combination of small things that all add up to steal power.

Not sure what else I can tell you about his setup. Its an 85 vette with the 160 ECM, the same as Corkvette is running with 11.10@124 in his 406.

 

WOW.

That sounds impressive.

I'd just like to know what he's running for injectors, intake, MAF sensor and I'd love to get a copy of that bin to look at the timing tables.

Does he hang out over on corvetteforum.com?

I recently registered over there so I could bump ideas off of other 350/standard MAF peoples.

 

All I've done really is ported plenum, cold air intake, 52mm edelbrock bbk TB.

 

SydwayzTA 86,

i will be the first to appologize to you that your post became a battle ground for verbal warfare. That is not fair to you and you have my appologies.

Moving on. My recomondations to you if you are just starting out and you are trying to get your feet wet with tuning. If you start with the system you already have, through learning that system you will learn the techniques etc needed to tune the system. Form that experience you will gain insight into other available systems and you can make for yourself a logical decision whether you will benifit from the switch. I have voiced my opinion, and you can see what your current system can handle HP wise, from my ET/MPH which is 450+ RWHP and gobs of Torque.

I'm here is you have any specific questions. make an informed decision and you will he happy.

 

Its alright, once all that started going on I kinda just backed off. thank you for the help though, its very appreciated, I'm not trying to get my car un-godly fast, I'll be happy with around 350hp. any imput on me doing that with a 5.0 or 5.7 ? I'd like to stay 5.0

 

Well a very nice proven setup is the 350/219/SR setup with some 190 AFR heads, will take you into the mid-low 12s easily and produce ~320 RWHP on average, so that is more than you asked but its a real nice system that will not effect drivability etc. Total cost if doing it yourself is well under 5k.

As for the 305, I have never messed with them much so I will leave that to the others....Good luck!

 

yeah i would be doing the work myself. 5k.. eek, prolly gonna be a long term project for my broke A$$. ah well, one can only dream

 

The heads are the biggest chunk if it. Do them first along with the cam, although they will not be pushed to their potential with the stock intake, you can then do it in pieces. That was my plan till I got carried away....now look at where I am at. LOL.

Already taking about a 406 with a SC to hit mid 9s with.....

 

LOL yeah you've turned into a mad scientist it seems, btw is your car street legal/ smog legal.

I already have a edelbrock performer cam and hydraulic lifters btw, and a 350 block, (dead stripped) in the garage

 

Its street legal no smog police here, and I wouldn't be afraid to drive it 6 hours on a trip either. The fact of the matter its as street friendly as my 350 was. Only this thing has about 4 times as much power, by the buttmeter, probably putting out about 150 more horses than the 350 setup is my guess. But a whole lot more torque...probably around 200 more ft/lbs. The thing will pull like no tomorrow, the one run I shortshifted 2nd gear by accidentally hitting the shifter past second into third, easy to do if your not careful, anyways second gear only lasted a second then it shifted into third for the rest of the way down the track. It still turned an 11.3sec 1/4! So there is more power in this thing than any street car needs.

 

*** damn no kidding, yeah i'd be happy with 12sec 1/4. i've heard of it done on a 305 but dont know what extent the people went to do it. i was also wonder since 350 wasnt an option in 86 t/a, if it would bring up issues at all to have it in my car, being in California

 

Got me...cali is a weird place and I am glad its 3k miles away from me j/k of course. Although you do have some strange goons there. [edit] but nearly every chick has big bizznoobies Maybe I'm not glad anymore that I think of it.

 

haha yeah but it goes both ways, the girlies look good and all, but most of them are just a little too experienced if ya know what i mean

 

Just play dumb and let them teach you.

 

hahaha, well if I wasnt already happyily engaged i would most def agree
