I had to laugh when i saw the manifold gasket you're using. lol

try doing it with one that's not giving it vaccum leaks from hell. Or at least show the A/F so you can see somethings horrible wrong.

Don't try to say that gasket actually sealed to the head. No way in hell that would work.

lol ya we are in the heart of winter, half the people out here dont even have their cars out of storage, as well im not doing anything to my car in this crap lol. dynos will happen, tom will do it again, i plan to, after ho cams and the finished p&p on my head. if i hadnt sold my lo mani id try and get the shop to agree all 3, ho, lo, and stock 2.4 mani runs. idk i can prob pick up another for like 10 bucks so i might as well, we'll see soon enough, just dont know if i want to take the time/work and create 3 similar tunes for each mani, itd be nice but idk if i see me taking the time.


idk how u got dragged into it mitdr774 lol
sorry

I was going to say that i dont remember making that post. Oh well it happens.

Well looks like i cant dyno on a stock motor anymore

^^ why not?

No way man,
lol
That was just a mock up.

I've done the swap before so I knew all about the leaks n stuff.
There were not any leaks when I put it on.

hehe upgraded some things.

I havent had a stock motor to dyno since 05. Right now is the closest its ever been but the balance shaft, HO cams, and 97 head disqualify it from being stock enough.

great info to have, i guess i wont be going to get a h.o. for my car this weekend



Eat my shift

Hey I have an Idea....... Whenever I find an adpater and install that LO mani (gunna leave my stock 2.4 tb on).... maybee we should stop by the shop your talking about and dyno my car... maybee we could even to a before and after... if I have everything prepped and ready to install (and you think we can swap it out in enought time........ although it sounds like I might have my cams in by then

THIS POST IS VERY HUGE.

IN RESUME WITCH MANI IS BETTER?

Don't even... you found the post by searching, now read it.

exactly what i was thinking

heres the thing with dynos though which is why i dont like them.

when dynoing you have to at lease get 3 base runs on the mod and then take the average. then put in the next mod and do 3 runs and then take the average.

there are so many factors when you do one pull and then another. you will see that between dynos pulls you can get as much as +10 or -10 whp difference between runs.

sometimes because the computer and how it reacts to the conditions.

best way to see if the mod works is to do 1/4 mile runs.

yes and no. you can gain anywhere from a tenth of a second to 3 tenths of a second between runs.
i ran with the HO mani and tb. i lost .3 tenths of my 1/4 mile time

I most around 6/10ths of a second on the L.O. mani, hope fully we will see now I got the stock 2.4 mani on.

wow the lack of knowledge here is horrendous.

so a good way to tell if a mod works or not is to hit up the track eh?? MAYBE if you do a switch at the track and get it swapped within an hour. anybody whos anybody that has raced on a drag strip knows conditions change EVERY HOUR, what your car runs at 5:00 it may run something completely different at 6:00. also, you'd better be one hell of a consistent driver to even see a change.





Rollin' on question marks since 07.

dyno it with out the HO....then dyno it with the HO....lets all pitch in for someone to do a dyno run. But still believe HO manifold on a stock motor will loose HP and torque so you should go with maybe the LO or just stay with the plastic @!#$.


GMR has got nothing on this

dynos are wack you claim you have x whp but then hit the track and you run slow because something isnt right.

to me the best way of knowing if your car is fast is how much your 1/4 mile runs are.

You're gonna confuse folks

The dyno is strictly for hp/tq air fuel ratios etc. of an engines performance.

They are not to make claims with a cars velocity on the road.

People just like to associate certain hp/tq numbers with a cars velocity because of previous occurrences throughout the history of cars.

someone already did. thats what this whole thread was about

Letxen 3... I hate to say it, but those time's dont mean anything. I ran my car with no difference in mods on two different days and ran 3 tenths difference. The one day I ran a 15.4 and a couple weeks later I ran 15.7. Now if you ran the same temperature and same humidity with the same wind speeds, then I would take those times into consideration, but I highly doubt you could/did do that.

Quote:

Dynos show you what the car is capable of. The driver determines if the car lives up to that potential or not on the track. So dynos are no more or less "wack" (its spelled "whack", by the way) than track times. Between my 14.2 days and my eventual 13.6's in the Beetle, there were no mods except for seat time. Granted, dyno results can come out skewed when you have a crooked, inept, or just plain incompetent operator, but when you dyno on the same day, in the same gear, with the same correction factor, with as many variables removed as possible, they're pretty reliable. Now granted, there were some variables in Mastin's testing, but if you want to disprove his results, put up your time and money and go out and prove it with quantified evidence yourself, instead of bitching about how "whack" it is. I think "whack" is a more accurate description of what it is to spend a crapload of time and effort getting the HO manifold to fit, only to lose power from it...

Letxen3 must be the best drag racer in the world, to have every single launch perfect, nail every shift......


There is alot more room for human error by testing on the strip. Dynos are by no means perfect, but are alot more realible for accurate test results since it doesnt rely soo much on the human factor.
