What are the new Ferrari, Lamborghini and gtr putting down to the wheels these days?

 

Gonna play with the 2.9 and experiment with whatever shot hits 500whp first

 

That's insane! Can't wait to c how it

 

Makes me want to continue my plan to build a second engine so I can have a back up when I shoot for the stars...

 

Subd

 

Just dropped off the block to be bored, honed and decked Steve

 

What size shot are you going to start with? Any idea what nitrous kit you will go with? Timeframe for it being ready?

 

Looking good man. I saw most of the pics and FB. Glad your keeping it and moving forward. Now I finally get my ride in it when its done.

 

Lol ya me to^^^^^

 

Why such a large pulley?

 

FYI for the true TVS folks, I have been fooling around with different size pullies. Area47 brought my atttention to it, as I did not. Looks like 2.9 is the ideal pulley; less than that say 2.7 generates too much heat and I am not sure the gains are worth it. I am back to 2.9 and happy as a clam. 3.0 or 3.1 is kinda sad sack ....

For the guys who want big numbers on the dyno, thats a whole other story. I have enough trouble tracking my car and putting the engine at risk, getting big numbers say above 320 on a TVS will just lead to very short, sometimes prematurely short engine life. So I dont get into that.

Very few people have made their cars live a long time at high outputs. Area47 again was probably the longest, 90k miles before re ring, but he drove the car with HPT pretty much plugged in full time beside him, and adjusted tunes according to his immediate wish: street race . power? got that. road trip. mileage? got that. etc.

mere mortals are hardpressed to do that.

my .02c.

 

In for updates!

 

I plan to use my 2.9 with the ATI pulley for that reason. I'm trying to detune it to around your hp John or less for the canyons and daily. Then have sexy time button

 

I run 2.6 with ATI and am about to install my nitrous kit. Built and girdled motor. Not sure why bigger pulley is needed

 

A lot of unnecessary heat associated with pulling down past a 2.9.

For you and I with girdled built blocks it's one thing

John's speaking of the average individual bolting a TVS on for daily use.

 

Any fear of failure with built tvs car and 100 shot? Thats my plan?

 

He is talking about guys like me, playing the stock block lotto

 

But he is pullying up for nitrous. Im adding a shot on top of current setup. And i have put down more than other tvs cars

 

Shoot for the stars. Gov I'm with I'm gonna play stock block lotto until I can build a bottom end

 

Im on a stock block with forged parts. I ran a M62 with a 150 shot once on e85 32° of timing. Ya the Arp head studs didn't like that combo to much. But my block was fine.

 

dont tell me i gotta set my block on kill too...

a properly built engine should run reliably daily with spirited driving in the mix, should it not? someone stroke me and tell me so

 

32* timing is stupid at wot

 

guys figure this. the only thing the "stock| bottom end lacks is forged pistons. If that matters. Maybe it does. The rest is already pretty darn good. Forged crank. Rods? I would chose stock LSJ or LNF rods over chiwanese stuff anyday of the week/.


and I do/ never lost an Ecotec engine due to internal parts failure. Ever.

first failure: maf pulled out of airbox on track/ car ran real strong until it subied.
second failure: phenolic spacer leaked. changed motor, but nothing wrong with removed motor upon inspection.
Third failure: YYZ pulled high g's on track, did not have trap door pan on the motor ( lazy) paid the price oil starvation to rod bearings.


I run to 7600 with the limiter set at 7800.

 

you run an ati? blance shafts? delete?

i havent heard much of any internal failures either like rods, cranks pistons etc. its usually from a spark plug or leaning out or some stupid ****

 

not sure why smaller pulley is needed. Maybe you should look at back to back comparisons? Like have you done that, all other things being equal? Wondering.

For my part, 2.9 is way better than 2.7. waaaay better.
280 on 2.7 to 300 on 2.9 both on pump gas.
