If you're going to throw 60lbers in there at some point, you might throw a pulley on there as well while your at it is what my reasoning is : I guess the issue with that though would be spending the $ to tune it...

Darkmanx

where the 85 and 89mm come from why would you add bigger pullies than stock

some people might want to de-tune it for daily driving, winter, etc.

Darkmanx

detuning a car has nothing to do with adding bigger pulleys , just bull timing etc gheez.

or run less boost for a higher compression build

Preference maybe? It's just a listing of sizes and approx psi depending on mods.

Darkmanx

OK my bad. continue to teach the noobs , im going back to lurking.

paul1588

i have a question that i havent been able to find the answer to,is the tvs just more efficiant at the boost level its equivalent to on the m62 or is it more efficiant lets say 2.85 pulley to 2.85 pulley as far as less heat and such?

um, im not one of the TVS geniuses, but its better all around. puts out more psi with less heat iirc

Bika

ok i mis-used the term "detune." I meant "dial back the boost for various conditions."



happy now?

Darkmanx

No because hpt limits boost as well.

Bika

not everyone has 24/7 access to hptuners so

only on the LSJ HPT, even if it was available, wouldnt do **** for reducing my boost

Dainslaif

If you were going to switch to a bigger pulley wouldn't you want to adjust the tune accordingly anyways?

Bika

if your tune is worth a ****, your maf should be able to compensate for a different pulley without needing a retune

car_guy_09

Ok this may be a dumb question, But all of the TVS guys are on the stock pulley, So what kinda numbers would we see with say a built motor and a smaller pulley?

I guess what im asking is where is the brick wall at with the TVS? You know kinda how 260-270 seems to be the wall for the m62

For one, not everyone has been running on the stock pulley. For lsjwannabe, the majority of the time he had one on his lsj, he was using the 2.75" pulley. He even experimented with a 2.5 for a little while but discovered that pulley size was way more that the block and head could withstand on a regular basis.

As for a wall with the tvs, it's considered to be between 300 and 350, depending on the level of tuning invested into the car. It hasn't been determined yet as to how much power it can produce with a ported head, but that info will hopefully come soon.

I know someone posted here earlier talking about the mods he had and being ready for a swap without much trouble. I had a 2.85" pulley, 60's and an injen intake. I swapped the m62 for the tvs and the injen for a r.a.w. intake. Even with the major differences, my tune was more than enough to suffice for a base tune for my car, and calculated errors were small. So it can be done.

car_guy_09

Ahh i forgot about lsjwannabe's car....

Deathscythe

Yeah, he and Area47 are the ones who have gone the furthest with their builds.

car_guy_09

Yeah...

Area and his pixie dust dont count though

Deathscythe

Doesn't mean that he isn't a badass tuner though. However he does it, the proof of his ability is there.
