I was thinking about the Kooks LT's,now yesterday heard that Quebec will adopt a new law by 2013 any cars over 8yrs old will go for "emmissions tests"...anyone had such a test done with full aftermarket exhausts,or you guys swithched to your stock parts before going,or did your car pass with full modded exhaust??

Also,been reading a lot on guys with "blown eng." on SVT lately,most are high boost scenarios with either TVS or bigger blower(most of them had the I.West 10%) now...some say it's because of over reving combined with h.boost,some say it's the I.West,some say it's too much boost for 93oct. see "bad gas"(street pump gas)....now I have all elements on my set up BUT my car is a week-end cruiser with the wife so 90% of the time it's very normal driving.Should I run a mix of Torco all the time just to stay on the safe side with octane levels(I'm using 94 as it is),car will get punched once in a while and see the track a couple of times (2-3) during the season and I make sure to shift bellow 6k but that's it.I wouldn't mine using the Torco btw all the time,better be safe than sorry right...what are all your thoughts on these 2 subjects??

thx for any help on this guys!!(see a chart for torco mix here post 14#http://www.svtperformance.com/forums/shelby-gt500-150/813440-octane-boost.html

A lot of the blown engines seen out there has to do with high boost and too much timing (tuner?). IMO anything over 15-16 lbs of boost would be too much for 93 octane as well as too much on the stock block (long term use) . The other thing that matters greatly is the combination of parts and who did the tune.

(1)A good fuel system is a must.

(2)Correct sized injectors, proper high capacity fuel pumps,(no boost-a-pump) :nonono:

(3)large enough MAF with the proper flow bench transfer functions in the tune to match it.(not manipulated transfer functions based on a dyno data log monitoring short term fuel trims like many so called tuners do today ):nonono: That is a common denominator in most of the blown engines today, although never talked about nor admitted by the tuners who are doing that.....instead bad gas is usually the blame.

(4)Adaquate SC intercooler system (upgraded over the OEM one) Excessive AIT2 temps is another key factor. Ford has set the EEC to pull timing if the downstream air temps are excessive in order to protect from detonation. Some tuners may reduce the amount that timing may be reduced thus putting the engine at greater risk of incuring detonation.


(5)Good hi-flow cats (not clogged). Many have blown engines because the passenger side cat had clogged and they raced or drove the car hard in that condition without knowing it.(seen especially in cars with ARH)


IMO if the combiination of parts is good and the tune is done properly and safely (not on the edge) Torco is not necessary especially in a mainly street driven car. You could always throw a can in when going to the track.

As far as going through a full emissions test with LT's and hi-flow cats I'll let you know as I am in the process of taking mine in...All O2's, EGR, Evap systems, Cat temp sw etc has to be turnned on and the readyness test must be completed in order to pass emissions at least here in CT.

Thx for the heads up George,have 110% confidence in my tuner and parts list that he told me to change,I just got wondering when I saw the I.West,high boost,(93 pump gas..sometimes bad gas,according to a few)..just want to be sure(especially with the octane),these eng. builds are quite expensive...at least from what I can see,running torco is a good insurance with the octane issue...would there be any issue if running torco all the time(I was thinking of a mix like this 15gal of 93 with 32 oz of torco = 96...for the entire season as a precaution)


Will wait on your "emmissions test results" for sure...thx for the help again George.Is there any problem with putting back all stock exhaust for these tests if it ever comes down to that?? Anyone else ever went for emmissions with full exhaust??

Pat.

with my 07, i ran the TVS, etc..making 711 rwhp, but maintained 15lbs boost....for the very reason Birdy states....never had an issue....15lbs was plenty for my needs...

I hear you Keith,my problem (if it is one??) is with all my set up less the exhaust(all I have is an x-pipe with high flow and FRPP mufflers,last fall dyno showed me 20psi boost...now I love my power,torque and don't want to mod, anything cause this is the way I like it now.Those are my reason on asking info on how much boost will I drop with Kook's LT's and x-pipe h.flow cats? should I run torco ro be safe?...like i said,love my combo and mods but don't want to blow anything up!!(but I'm very easy on the car,it doesn't get beaten up to death at all...) sorry for all the questions,just trying to get the most info that I can!!

copy...not sure about kook's, but i was running AR 1-7/8" headers on mine...there was a few lbs drop, just not sure how much. But after dialing it all in, i was at 15, with plenty of power..what HP are you at currently? if you consistently run torco, i think the CATS would suffer from it...dunno...maybe others can chime in...if your not beating on it, that helps.....but for how long...dunno...

last fall dyno showed me 20psi boost...


Tick, Tock...

:giggle:


Headers would drop that down a psi or two... Might as well do a BMR K Member at the same time... http://store.bvmperformance.com/

I am running 15psi with the TVS w/2.6 pulley... Kook headers, sans cats... 586 rwhp on a Canadian Mustang dyno, so that's probably about 725 on an American Dynojet...

My rwhp was low 600's,(601-605 on mustang dyno)mind you my x-pipe has been on the car for 2yrs already...might have to check the cats..could be clogged!!! anyway that will get change next spring!

Torco eventually fouls plugs so you will have to change plugs more often....just my experience anyway. Not positive that is true across the board. I think Iceman was having the same issue?

I'm not running Torco in the track car anymore just so I don't have to change plugs so often. Just lowering my RPM's a bit at the track to be safe.

lolll,if it ever happens,I have a plan though...but still hope not too..

Thx for the help Bill,if that's the only bad side,I'd change them every season...thx again!!

Any clue about my exhaust question and the emissions tests??(putting the stock one back ON,would that affect the car's computer in anyway??

I changed the plugs on my track car after about 500 miles w/ the Torco. :shades:

You may want Iceman's input on a GT500.

I don't know about the computer effects and emmissions....I'm not that smart. :innocent:

:iagree:

No way would I run torco on a regular basis as it will coat everything in the combustion chamber especially the plugs.....:nonono:

With 20 lbs of boost and stock cats you are at great risk of damage to the cats and to detonation from excessive heat. That's why LT's would be so benificial in your case.

You should be able to get through emissions with the Kooks LT's and cats system. I don't think you'll need to make any changes to your tune with the kooks headers because of the position of the cats in their system. You would however need to have all the corresponding emission switches turned on and a drive cycle completed before the test.

I'll let you know how it goes with mine as soon as I get the chance to take it.

The computer would relearn after so many miles Loco... You could have an emissions tune for the cats and then a tune for no cats after you pass the test... Or get to know someone who will be doing the testing...

Thx George,so no torco for daily use,that's good to know,wasn't aware of this...As far for the cats,I'm not running the stock one's,I have a (think) magnaflow x-pipe with high flows...reason probably that I have high boost is think that they could be clogged up?? never checked them since installation 2yrs ago...When Keith explained his boost levels and so Stacey's (15lbs) that's what came to mind...like I said,when I did the dyno session,was talking with my tuner and mecanic all thru the afternoon,they did a great job,then I put the car away,that's why I'm asking questions now to start my plan for the spring...

"You would however need to have all the corresponding emission switches turned on and a drive cycle completed before the test"....This I'll need to know what to do exactly as well!!

Thx for all your help guys,appecreciate it.:tiphat2:
