Last night i finally made it back to the track to test out the new 4400/3.0str TCS vs. my TCS 4200/2.7str and 2.5str i had in the car. Between the two 4200s there was a .05 tenth gain with the 2.7str but the 2.5str was 1/2 MPH faster trap speeds than the 2.7str. With equal 60fts. the 4400/3.0 was averageing .1 tenth gain in the 1/4 mile but the MPH was the same (weather related i think) This was a night when most regulars were a tenth to 2 tenth slower than the weeks before,so it goes to say that their COULD be a chance that it could be .2 tenth gain in ET between the 4400 vs. 4200 but i will not get into what could be and stick with the facts that it did prove to be faster to the 330 mark,1/8th mile and 1000ft. but with equal MPH.

I think that the MPH could be affected by the weather conditions and also most of the time a looser converter will give up a tad bit of MPH from what i seen,so all in all i actually might have gained a tad MPH given the circumstances. As far as 60fts. go the 4400 was .03-.05 faster than the 4200. I saw an average of .03 gain at the 60ft. all night with POOR track conditions. As you know or do not know my shift extentions were raised more with the 4400 over the 4200. I had derek to set my 4200s up with shift extentions in the 5500 rpm range and had the 4400 bumped up to 5800 rpms. It is noticeably stronger with the higher shift extentions for the cam and i honestly think that with a lower shift extention i would have only gained .05 tenth between the two but let me tell you this converter charges HARD through the 1/8th mile and 1000ft. then levels off a tad before the 1/4 mile. First run down the track i spun a 1.61 60ft. but the car never bogged on the shifts and pulled like a raped ape down the track lol I could not belive the difference but it was there.

I really like the 4200 but the 4400 seems to help the cam and 4.10s out a little bit more. This converter should be a solid 1.4 60ft. converter with cold air and good track prep. I went on a import night and got caught up in the water pit launch pad but i got an acurate test between the 3 converters with equal 60fts.

For a bolt on car yes it will work but i would go with less shift extention. For a cam or heads/cam car this is the converter that will shine in the higher rpms along with aggresive gearing IMO. With my 4.10s and 26x10 ET Drags i cross the traps at 6500 rpms and that is right on the money for my power curve for my cam. I'll go back to a different track in a few weeks and see if i can nail down some low 1.5 60fts. I can't wait for winter time air

could you do some detailed timeslips...PLEASE

StreetStalkerZ

Lynda,If i can remeber the timeslip right it was:

TCS 4200
60ft. 1.62
1/8th 7.48@92 MPH
ET 11.78@114.8x

TCS 4400
60ft. 1.61
1/8th 7.42@92 MPH
ET 11.69@114.73

My 2nd pass of the night was

60ft. 1.59
1/8th 7.40@92 MPH
ET 11.69@114.3x

As you can see as the night went on the car was making more power but the track started to go away on my 3rd run. The first 11.69 you see was on my last pass (6th run).This was the closest comparison of the two. The 4200 that night was averageing 1.65-1.64 while the 4400 was averageing 1.61 without a dead hook while the 4200 was hooking better. Their track prep SUCKS! but i stuck with the same track because of some people saying different tracks will throw off the comparison and make it unfare between the two converters. I normaly drop about .03-.05 in 60ft. going to the other track so i guess you know where i will be going in a few weeks

Looking good. I wonder sometimes a converter bigger than my PT4200 would net me better times. My shift extentions are up there pretty good right now, 5900ish. My best 60 ft time has been 1.58 on ET streets spinning a bit. With ET drags or hoosier slicks I will probably be close to the 1.4s. I guess I can't complain really. I just wonder what a slightly bigger converter would do in my car.

Man I bet that thing is a beast. Can it even be driven on the street with drag radials? 3.0 str is sick congrats

Yea from a 2nd gear punch lol and then you might spin a little. On ET drags from a first gear punch it will roast them through first gear and half of 2nd gear without a burnout

quickWS6

My 4200 2.7 STR, burns them all the way through 2nd and gets sideways hitting third from a dead stop. I can only imagine a 4400 3.0 STR with a bigger cam.

Hey Scott good runs. Last night at about +1900Da with 84% humidity I made a couple of passes on my car. I was running my 27x11.5x15 QTP(bracket setup) which are really 1 inch too tall for my combo. I ran 1.55 60ft 7.38 91.43 and 11.67 114.79. With the 26x10x15 ET drags I usually pick up .04 and a 1/2 mph. I'm hopeing for mid 1.40's in cold weather also. Good Luck Frank95z (obsolete na stockhead Lt1)

Nice times with the new convertor. Good writeup and very informative. Cheers...

awesome and thanks for the info.. if i take my vig3600 out im gonna get the 4200 or 4400TCS

Frank,good runs for the weather. Your car runs very well for what you have and i hope you run your ETs that you want later on in the year. I would like to make a trip down the NPR early next year if i can get the cage and harness in,so we need to line them up again.

98TAauto,either one of those TCS will out do your Vig.3600. Just figure out how hard you want it to hit,shift extentions and looseness. The 4200 will be about as loose as your 3600 to give you an idea. The 4400 is looser than the 4200,more than you think.

I got the ASP pulley on last night,so i am going to try to bust some 11.50s in this summer time air

Frank95z

Scott Does that means no thurder shootout for you being that you're talking about coming early next year. If possible you need to come on down. You missed a great event last year. We could race 1/8 mile or 1000ft and you wouldn't be booted. But you would still be owned Frank95z

Frank,there are several things standing in my way of coming to the shootout besides passing tech that would be a trailor and finding someone to swap work days that weekend with me. I would love to come down and spank...i mean race you and im trying my best to figure a way to get down there. If i do i'll end up having to leave friday night,can i still enter the event that late?

CamaroCain

iTrader: (1)

YES! There is early registration right now, but you can pull up to the gate Friday evening and tell them you want to run in QS or whatever. The event itself actually starts Saturday. Please try to come even if you don't bring the car, it will be a very fun event, I specatated last year and had a great time, but now I am lucky enough to have a car that can compete.

Frank95z

Scott there is several class in the thunder shoot out and bracket race both Saturday and Sunday. Come on down it will be fun. About that spanking you talked about Sar2k is the guy that likes spanking i like to Frank95z

Frank,hahaha yea i figure you like to drink and SAR2GAY (steve) likes the spankings from all the pics shown on ls1.com from timmaayy gay club scene they go to

Lynda,i'll try to make it but i can't promise to be there with having to work that weekend. I can call in sick but that would cut me out of $600

I have been considering the 4200/2.7 for my car, think it would be a decent match for the TR230/224 cam?

Found some interesting test data performed by General Motors on the TCS 4400 Violator. TCS Claims 3.0 STR and 98% efficiency. GM's test showed 2.16 STR and 89.81% efficiency at 7,000 rpms. Efficiency was worse the lower the rpms got. No wonder you lost mph.

I got mixed feelings about this. One i can't discuss yet until i make a phone call and the other is that there are alot of BIG name people running the TCS that have gained ET and MPH from them over Yank and P.I. so i do not take everything that GM says to heart because there are alot of factor in testing between different companies and to me it looks like Yank paid them to do this test. I personally know of 2 cars that had their Yank converter to come apart on them while driving down the road.

quickWS6

I would not believe this simply because it is on Yank's website. Any company is going to try and make itself look better than anyone else.
