i wont be going to the track
i only play on the street
i will be using nitto NT555R 315s to hook up
my goal is to be in the ~400 hp area
using the G5X2 cam, stock heads, 3.42 gears

what is the most stall and STR i can get w/out having traction problems?

i was thinking 3800 and 2.0-2.2?

anyone know whats up on the street?
you know it is not prepped like track.
hopefully i will order tomorrow and install myself!

 

4400 and 2.7 STR.

The looser the converter, the easier it is to pedal your launch. When I had my YTP 4000 and 3.23s I could launch really well with 245 nittos. 3.73s made it much trickier to launch on the street.

I'd go a 4000 stall with a 2.0 STR. You don't need much STR except for drivability.

 

good recomendation, but maybe et streets would help, or even slicks if your rear will hold.
Maybe only stick 'em on when you know it's time to play?

 

I've been 1.59 60ft on 315 Nitto's a couple of times with a Yank TP-4200 ~2.7 STR.

Also, went 1.59 60ft with a UT-4600 ~2.9 STR.

It's real hit or miss with street tires, even with big DR's. ET streets or QTP's are the way to go.

Ragtop's recomendation will probably work best if you never want to use a "sticky" tire.

 

i dont want to swap ET streets
i want to run just those nitto dr's
(unless you know of stickier tires that still last as long)
and ready to go anytime!
i dont want to lose to some dude in an import because i cant hook up, and then have to say, "wait till i get home and get my ET streets!"
you know what im saying?
also, i may just do a run from stoplight to stoplight, so i dont know if i wanna feather it at launch and gradually pull.
since its the street, i'd like a nice hard launch right off the line, but also, because its the street, i dont want to have too much stall and STR and get traction problems

what do you guys think?

do you think i can really flash the convertor off the line w/ 4000 2.0?

 

If you just worried about stoplight racing and want to mash it and not think, then you need a 3000 stall with 1.6 STR. It will be suboptimal for anything else but meets your criteria.

The trick on the street is to not overwhelm the tires and have them grab so that you overcome the interia and progressively add power. If you want to use a smaller converter to make less power out of the hole you might hook cleaner but you will be slower beyond the first hundred feet.

Imports are mostly M6's and they like to go from a roll too. An efficent 4000 stall will give your car the pull from a roll to hang with them.

A Superyank 3500 would probably meet your needs. Still can roast nittos on the street but it is the eaisest to launch converter I've driven.

 

Dont mean to barge in this thread with a dumb question, but will someone fill me in with what STR is? I too wanna figure out whats the perfect converter for me. My car is a daily driver and will see about 95% of its time driven on the street. However, I do want it to be a good one to race on the street and at the track. I made a thread about what converter to get, but now that Ive read this one, Im confused because of the STR thing. So what Im looking for is a good converter thats very streetable, but will do awesome when I want to play around on the street and when I take it to the track. Thanks guys.

 

I am no expert

but STR is how hard your converter is gonna hit.
As mentioned abover the SY3500 has a low STR (1.86) so you might be pretty good with mashing the pedal and going, stalls like the ST3500 with I believe a 3.0 STR will roast the tires, atleast on my friends car it did. He has 0% chance of hooking on the street but he has pilot sports and not DR's.

Again I am not expert in this field, kinda picked up some knowledge as I read and read and read....
Ragtop99 seems to be one of the most knowledgable TC guys here, so I would listen to him. Though that 4400 with 2.7 sounds awfully big for a street car, but I understand what he is saying and it definetly makes sense.....

If I were you I would opt for the SY3500, it doesn't sound like you want to get the most performance out of the TC for track purposes, but the SY3500 is a kick a$$ TC, people normally see .3-.6 off their 1/4

 

Well in a way I want to do good at the track, but Im not buying the converter just for it. I want it to be streetable, but will do badass at the track. Being streetable all ties in with what stall speed, STR, gear, tranny, and whether its locked or not. Please correct me if Im wrong 'cause I probably am! I just want to be able to get at least 15 to 18 in the city give or take. Nothing below 15, but I want it to do really well at the track. I hear guys running in the 11's with internally stock motors and that makes me so damn jealous! If Im running all the bolt ons and cam/valvetrain and pushing about 420rwhp, then hopefully I want to be in the low to mid 11s. I know for sure I want it to be in the range of mid to high 11s. I hope that helps a little more for anyone who is trying to help me decide. Thanks

 

i think NVMySS and i are looking for a similar converter. i plan to make ~420rwhp when i am done with this thing. but i heard the converter is the first thing i should do so here i am.

so far from what i have read and heard,
i should either get a 4000 2.0
or a 3800 2.2

can i hook up on the street with either one?
which one will 1/4 faster?

 

Simple answer...get a TCS..they come with fee restalls. Id lean toward a 3200-3500 with a 2/2-2.5 str.. hit good, can be made tight for driveability and still give you good goose.

 

can you launch hard from a dead stop w/ your 3500 2.5 on the street?

i am considering ~2.5 STR..
a kick in the pants off the line to me is more important then being more efficient at 160mph.

but will i hook up?

-i called john at hpa today.. (for midwest)
he was kinda rushing through things
we got cut off
i called back
no one picked up..

wondering if i should go with another company..

 

There is no way you are going to launch hard on the street without spinning with a 2.5 str. I have a TCI ssf 3500 w/2.5 str. and 3.23 gears with 315 Nitto DR's on 17x11 rims and still spin through 1st gear. If you leave traction control on you spin just a little and then it takes off, but you still won't get the most out of the launch.

 

Do you plan on spraying the car at all? If so, you need to think about getting a smaller converter or finding someone that gives free restalls. A 4400 converter on top of 100+ shot of nitrous does not like the rev limiter! If nitrous is the case, I suggest going with a 3200-3600. If you are going to stay all motor, you can consider a larger converter. However, if you want to keep it streetable you might be a bit more limited. I am running around on 315 Nittos and a 3200 Vigi. I sent my old converter back to Vickie at Precision for a little help because of past problems... She really worked with me and they found the best application for my car. I have gotten some really good launches on the street but if you are looking for track style launches, expect to prep the street just like the track. You can always go out there and heat up the street with a blow torch and throw down some VHT. Do a good burnout and I can personally guarantee a great launch if you know what you are doing! However, I can't promise that you won't break anything. It might take you a while to find what works for you....

Just my .02!

 

Anything with a 2.0 or higher STR will kill the street tires. It's all in learning to drives your combo. My car drive perfect without spinning a tire on the street... but I also know how to 'pedal' it.

I think a SY-3500 is the converter your looking for.

 

what STR is the SY3500?
can i just get any convertor at 3500/???str?
or will getting THAT one make a difference?

basically, i want the best street convertor available. from the best stoplight launch i can get on crappy 315 drag radials, to ~100mph or so

if i get something too big,
can i launch well if i ease into it?
or does high stall just turn the gas pedal into an on/off switch?

 

SY3500=1.7str

But why don't you call TCS and have them build you a converter to what your looking for....plus I think they are running a GP now

 

I st3500 str 2.5 w/nitto 315's forget hooking at the track and they are not to bad on the street if you dont nail it off the line but ease into it a little. all in all i love it just need some et streets for the track

 

I ran a SY-3500 in my 99 SS. I had the upgraded STR (1.86). It did very well on the street with 275 DR's.

 

Must have been a bad track prep or some other factor. full bolt-ons + ST 3500 + 245 Nittos = 1.68 60' in good weather We have a number of EFA guys running high 1.5x and low 1.6x on nittos.
