Not just dynos, but also the volume versus mass thing. Mass of any specific volume of air is going to change a whole heck of a lot at different temperatures.

But anyway, my point of posting in this thread is:

Has anyone broken a CTI downpipe yet? I haven't seen one break myself, and they are priced very competitively with the ZZP downpipes.

Hey!! I wants mine first!

Nope my dp is just fine going on 2 years now.

Timing is not a end all i would not get hung up on it

an0malous

true enough. though these cars really seem to like making power through timing.
and i honestly would be a bit worried about egts at low teens timing....

Area47

once you start moving crap tons of air. you don't need as much timing.

I have just about every cooling mod possible and it still runs way too hot

i got cx racing intercooler biggest that will fit, gm dual pass option b

only things left is possbly co2 on the intercooler and co2 on the intake pipe, and killer chiller

I thought you didn't have meth? Unless I misread something, highly possible lol

an0malous

can you define "to hot" for me? (iat2s)
and what are your ambient temps?

Area47

my iat's were pushing 152 saturday on my runs with the terbow lexus, thats in the middle of 4th gear. that too me is a bit warm.

an0malous

yeah, its been very warm around here lately too....(cruising IAT2s hovering at 100)
I dont like workin the car hard at all when its that warm,
takes very little to get it into the 140s-150s

well these runs on the dyno were without it (meth), but i have it now and ive seen little improvement

iat1s have been in the 80s and im generally about 40 more than IAT 1 regardless of the temp

Was the 278whp number the Dynojet estimation or the Dyno Dynamics figure?

shabodah

If he's really running "too" hot (wrong to, too, two), maybe he's jumping the gun on the 75mm pulley. I know 270 whp can be made on the 85mm pulley.

how much of a power difference is there going to be going from 11.0AFR to 11.5?

that would give a clearer picture of what ill be making once the tune is cleared up

I can say an M62 car w/ 2.6+meth running 21* (17lbs) pulls noticably harder than a TVS car w/2.7 no meth running *9-10 (24lbs). Both 10:1's and 272's.

From what I've seen these cars like timing more than boost, but with 2 different compressors, eh, can't really make a fair comparison.

shabodah

And if you're just cramming as much air in there as you can, things are likely getting too hot to run proper timing.

Everything I've seen points to the fact that at the same mass of air, the TVS should have cooler air and thus allow better timing and therefore, more power.

Area47

if you can cram 25 degree's of timing down the next of the lsj with the tvs. you're onto sometimes. if you can't run more than 12 degree's. you might as well stick the m62 back on it.

Darkmanx

your car is fucked sell me your tvs.

pjk91

I'm running around 16-17* right now, stock pulley, no knock. What do you think a TVS on the 85mm, and the 2.4 would do? You think I'd even be able to run 16-17* on the 2.4, since the cr is a bit high? I want to stick with 93octane. Maybe if I threw some meth at it, it would work well.

Area47

according to zoomer. i don't know anything.

Altiery54

well at him.

very interesting

Blown 4-banger

My car with a 2.6" no meth at 14-15* timing (20 lbs), pulled a couple car lengths on a stage 2 + 2.8 (15 lbs) running 23* timing.

ls1fbody

im just glad you broke the exhaust, not anything insde the motor.

Blown 4-banger

Someone with a built ass motor needs to strap a TVS on, and see what it does!!! Just cramming 24 lbs of boost into a stock head/cams motor is not going to yield exciting results!!!

whats your definiton of exciting?
