Finally Dynod My TVS Setup
#52
You did not fully read the OP's first post....
I'll give you a hint (13*, 11.3 AFR, conservative).
People who think just bolting on a TVS will net you an easy 300whp are out in left field.
Without proper octane, timing, revs you will not see those kinds of numbers.
When the OP bumps up the timing and leans out the AFR a bit he will see over 300whp with his current setup for sure.

It seems like most people think just throwing smaller and smaller pulleys for more and more boost will automatically make high hp. More boost will generally provide more TQ fairly easily, but the high peak HP is a bit harder to get to just by when cramming a bunch of hot air into the engine. Guys like Area who have a lot of time tuning a lot of different engines and setups know all the little tweaks to get all the power out. Although a lot of it is just your basic MAF, PE, High Octane Timing tables but that's not all of it...from what I've understood/read this far
I think I still have a graph of my stock m62 setup that i tuned a bit compared to one of my first pulls with the tvs and they made similar power/tq curves even though the tvs was about 1 point richer from low-mid range and about .5 point leaner from mid-top end and had KR over 7000rpms
found it

He probably could not run more then 15* of timing with that pulley and his setup. Conservative is one thing. But 2 more degrees of timing is not going to get him another 17whp.
I would go back to the stock pulley to run a little more timing and cut back on the heat.
Just because people go fast with the GMPP exhaust doesn't mean its the proper exhaust for a TVS car or that they wouldn't do better with different exhaust, you guys are using flawed logic. There's no reason to believe 2.25" exhaust is the best option for cars flowing over 25(if not 30-35)lbs/min MAF.
Its the fact that you have mechanically driven induction that's seems to mask the inefficiency of the small pipes.

There is KR at the top of that run. Maybe a larger exhaust would have prevented that.

Well they still do... N E Way.
The point is, if someone wants to do the TVS, do it right...

Timing plays a huge role in the power
TVS is fun, but gotta pay to play as the saying goes.
luckily for me im not shooting for stupid high numbers though 300-350 would suit me just peachy but im more in for the nice high broad tq curve
...wish i had E around here

The power difference is so noticable between pump gas and e85 on my car that I stockpile e85 in gas cans. The closest station is 30 minutes away, so i fill up gas cans everytime i go through. After feeling the car on 27* of timing.. 15* sucks hardcore.

So started leaning the afr a little bit today to 11.8 and remodified my timing map a little bit to see how far i can push it , ramped the timing a bit up to 18 degrees uptop over 6k rpms, activated my meth pump, however its only spraying a 100% distilled water on a 3gph nozzle, the last 5 gallons were distilled water in it so I know there's no meth left I made serveral runs on 93 pump gas " E10 " Didnt see any knock during WOT, however did see the usual knock when im at lower rpms, thank you solid mounts lol
I'll get it dynod soon and will try to log the runs to get all the stats
Anyways heres the timing map that Im using atm and will be modifying a bit
And here's the KR log

Yeah, The closest e-85 station to me is like 35-40 min away, I want an e-85 tune soooo Bad but its so damn far away, How many gas cans do you fill up and how many gallons do they hold? Is it very Inconvienient?

I agree 100%. People flash those results around like it is the standard. IMHO. It is far from it...

I also run it mixed 50/50, so it lasts alot longer than it would if i were running full e85.
Its not particularly convenient, but it's worth it to me!

My job requires me to travel through the town with the nearest station at least once per week. I just rotate out two cans. Sometimes i need one.. sometimes i take both with me.

Own personal satisfaction eh? Lol well what was your et? If i were u and your trapping what u say why not jump on the list with me as one of the fastest tvs cars? Unless your lack of et contributed to the faster trap mph
#66
One for one lol. It's been proven that running full E85 doesn't really net better results than e47 and the fact that its less harsh on the fuel system is beneficial as well
#67
I can get pretty agressive with the timing and get away with it on 50/50, so it works for me.

How much extra WHP do you think you are netting from going e-85?

Oh Ok, Thanks Zrated, Ummm, So do you have 2 different tunes or just the e-85 tune? Thats what I thought in terms of how to mix it, I just wanted to make sure, So 5 gallon container of e-85 and then just pump 5 gallons on 93 Octane pump gas correct?
