Random Questions ????? Post Them Here !!! ???? ?????

i'm gonna dub with the MAF this weekend, move it to the cold side of the intake, drive it see if it calms down and if not i will plumb the BOV return and move the MAF back to the inlet to the compressor, or just try t hat first, either way if i can get it so i don't have that spike it will be good, not planning on breaking 200 at the wheels but 18psi should show decent numbers for 8 valves, pending that we will set up a date to get this swedish peice hooked up. Thanks for the insight. always appreciated

. It's a 3000 lb drum, so it takes a bit to get it sped up anyway.

jeez... my mr2 doesnt weigh close to that... lol

Lol, that's ok. It's all about how fast you can get it spinning .

Yeah its just uses "simple" math. If it was an eddy current dyno, you could have issues with the drum weight twice what the car does. We ran into that last time the race car went out, a 600 pound car on 1300 pound rollers, got the car up to 57 mph and thats it, I've driven it in real life faster than that, had a couple other issues though (intake that leaks more than it seals, never been run in sub 60* weather before and it was 40* out, etc)

lol well the way its been acting lately.... i think my tc would almost have a better shot lol i def wanna make it down there soon.... embarass myself a bit haha

got a question... is this something youve heard of before?

I side with Trey and all his points. All the mods posted are not ground breaking and dynos for all these parts in all combinations are plentiful. Most of us G diehards know that an intake doesn't do anything on these cars, the MD spacer is good for 7whp to 8whp, a catback is worth 5whp to 8whp, and tuning on a car with the typical bolt-ons is worth 5whp to 10whp. These numbers just aren't making sense.

A few things I'd like to point out. I've never dynoed my car, but I've dynoed other VQs I've owned and I've watched many a VQ30 and VQ35 get dynoed. Something I've noticed, especially with the VQ35s, is that they tend to get stronger after each successive dyno. It's has if the ECU is slightly confused at first when the rear tires are traveling faster than the fronts and power is killed. After each dyno, the ECU becomes more accepting. It's not uncommon to see a 10whp between the first dyno and the 3rd or 4th.

Secondly, since this is a Dynapack you can adjust load which then could affect power. Not saying these guys are doing it, but you could manipulate the power numbers by varying the drum brake. Dynapacks and other brake dynos are ideal tuning dynos because you can apply heavy load.

Finally, I'll really interesting in seeing some picks of these longtubes. I highly doubt they make 30whp like they do on the LSX, but I'm sure they could make a legit 15whp-20whp. Longtudes are where it's at when it comes to making power and fattening up the powerband.

I got it from a g35 forum.. ive been trying to figure out about what a my stock G makes for power. Ive seen alot of different numbers- mostly for non-revups. Im just trying to figure out what a stock 2005 rev-up 6mt makes on say a dynojet. one of the vendors on there was saying he got 242whp and 210wtq, another vendor said he would agree on the hp but said the tqe numbers were low... any idears about what it would be?? i know, i know, the best thing would be to bring my lazy a$$ down to ya and see for myself.. lol

The 350z we had at our club dyno day a couple years ago did this. We couldnt figure out why it was getting stronger as it got heat soaked.

that's a hard choice, pay for 10 hours of dyno time to get 20whp more or buy parts to get the same amount!

And then pay for dyno time to make those parts work right.

Bring it down and see. I generally do 2 back to back pulls and see if the power climbs. If its weaker after the second pull ill let it sit and cool down for a few before the third pull. If it keeps climbing we go till it drops .
Z's, 05+ mustangs and LS cars tend to make more power until they get to the optimum temp. I think its because of the head and specifically the combustion chamber temps. Too cold and it doesn't burn right, too hot and it knocks or loosed power first. I cent say that's the answer, but it seems if the block and heads are cool, it won't make optimum power.

Bring your G down and let's see.

My Evo for some reason was like this on alexs dyno. After 4pulls it gained like 40whp the hotter it got

I gotta come up with some extra moola first.. then figure out what goodies i wanna toss in it afterward..

Just dyno'd my brother in-laws 06 GTO (LS2). Bone stock other then a K&N intake and axle back mufflers. Made 348 first pull, 350 second, 354 third, 358 fourth, then finally dropped back to 356 on the 5th pull.

Perfect example of what we said earlier.

if you had his G "plugged in" you could see if it was pulling power due to the "omgwtf" factor with the wheel speed sensors right?

For that type of power cuts I wouldn't even have to be plugged in lol.
