Deffinatly...

 

Good job on the numbers, AF ratio does look conservative. You're right about the methanol. Anything that raises octane works wonders for the TVS w/ a smaller pulley.

that's because nearly the entire forum has been misleading people about what to expect from the TVS and calling people who tell the truth liars and idiots.

a stock tvs pulley car shouldnt get you ;0nwhp with little to no supporting mods. but when you start to drop pulley sizes the power goes up fast. alot faster than the m62. im glad your happy. now go and push the car a bit and make some crazy power

 

the potential for 300whp is definately there. keeping it conservative right now is a good choice, IMO. like i said above, make the tune more aggressive and add meth.... all will be right

yea he's not making the greatest numbers from a TVS but the power he is putting down, is very effecient and seems to be extremely safe.

 

Zoomer, I'm convinced you're a little slow.

 

^even if you're just teasing.... that's uncalled for. dont need that crap in this thread.

 

I have a TVS RL. I do not have a big throttle body I am not interested in the idle tuning aggravation. I have not been to the dyno yet, but the road where I do my speed runs I can get to 140 mph in 1/3rd less distance than with my M62 on a 73 mm pulley.

I have meth, and an h/e in the stock location. It is a griffin. It is thicker than stock. I have a/c.

The torque/power curve is completely different to the M62. I find it better. It does not come on as hard as the M62 with a 73 mm pulley, but then I have an 80 mm pulley on the TVS, and when I move up to the 70 mm pulley i am sure that it will change things. In the meantime, it launches well and pulls very well.

I ran the car at Watkins Glen last week in 100 degree f ambients, the car did not slow down. It was faster than many BMW M3's ( I race on slicks). The times i cut would qualify me for a Grand Am Koni ST race.

The biggest difference? at 6000 rpm the M62 goes home for lunch, it does keep revving but what it really says to you is: "why bother I am out of my power band"

The Harrop never quits, it says "7500? is that all you want?" coz it keeps pulling for evah....wow!

My plan is to run Mosport against OGC's '08 Turbo 'balt next week, then Calabogie the week after. At the end of September I will dyno both 80 and 70 mm pullies and post them for Zoomer to call me names, and then go to the drag strip.
NOTE I will only run on Drag slicks, as the rest of this stuff that is being thrown out there about 1/4 times is not really fair. If I cant borrow slicks I aint gonna beat it to death at the drag strip.


Harrop TVS? Rock on, for me its awesome. And quiet. (the S/C, not the magnaflow muffler, its brandnew and blew out in two days. Yikes!)

The tune? Area 47. now on v.3. More to come as we get more log time...

The tune is very important.

 

You'll be a pal and let me use those slicks that day too right qwik? Then we'll see real times

 

i keep saying we need a seperate section in the lsj for tvs... some moderator needs to make a new subforum.

and i def love my tvs. the reason the m62 pulls harder ealier is cause you are spooling it faster earlier. put a tiny pulley on the tvs and see what it does

 

oh yea there is crazy potential with the TVS.

if there was a separate section for TVS then there would have to a separate section for turbo swapped also....

LSJ w/ M62
LSJ w/ TVS
LSJ turbo swapped

it could work, i guess

 

I am sorry to say that unless you run an option B bleed line, you have air constantly in your h/e circuit, and the heat transfer from the laminova does not work well with air in the coolant. Kinda like oil pressure feed to the crank with entrained air in the lubricant. Air in coolant or oil? Both result in failures. So keep working at it, with good help I think you will be fine. My TVS sure is fine.

always a pal to you bro' ! Everything I get for nothing, you get for nothing....

 

I put 265hp 225tq with the base tune of ottp and i want to hit 300hp with the 60s and stock pulley lets see what happen, was in a mustang dyno i think.

 

I just had a retune because I was getting knock between 3500rpm and 5000rpm. We had to pull the timing back by 2. But the change ended up netting me an extra 8whp and 5wtq. The knock was causing all sorts of issues and robbing some power. SO I am proud to say the cobalt is running awesome and the new numbers are:

282whp and 247wtq

I think my next move is definitely going to be 2.75 pulled, 79lb injectors, meth injection and a retune. I'm sure that will put me right around 300 hopefully more.

 

did you ever dyno with the m62 on to be able to compare?

why even go there? I don't see him calling you out or anything. Stop the trolling.

 

Update: Mosport Thursday, TVS RL qwiker than OGC's TC, ( he had R comp BFG, did an awesome driving job, bit he cant stay in the draft.) So, also qwiker than a Koni race Cobalt. They were giving sponsor rides, probably not trying. The OEM Power steering cant handle slick tires and a fast track (not news) so I gotta fix for that Friday /Saturday, and more track time next week (note meth is not working )....area47 tune v.4 is fine, even without meth and the car did not slow down at all...TVS rocks...oh and I have booked dyno time for the end of september beginning October....I will fix fuel system and go to 70 mm pulley in 2 weeks or so....

 

I did dyno the car on my m62. But I didn't get a copy of the dyno sheet. When I dynoed I had all of my modes on already (full exhaust, intake, stage 2, heat exchanger, etc.). But I was probably hurting my power with the 3" exhaust and downpipe. Anyways when I had the m62 on I was making 237whp and 209wtq. So the TVS has really changed my car completely. I'm really looking forward to adding a 2.75 pulley, 79lb injectors, and meth. I will hopefully make 300whp.

Honestly I doubt you will hit 300 with just a different tune. You at least need meth. And if you pulley down and get bigger injectors or a ruturn style you will probably do it. But not with your current mods. You have basically everything I do. I'm definatley as high as I'll go at 282whp and 247wtq. But that only leave 18 more horse to jump for me.
