Dynoed my dads car @ 17 psi
 

it was getting MAD wheelspin on the dyno, thats why it looks like it levels out and then spikes

The RPM pickup was off on the dyno.. i don't know why but it was being reved out to 9500~

Where it says 8500 = 9500 the squiglly line at the end is from bouncing off the rev limiter.

it gets 12 psi @ 5500 and then just slowly creeps to 17.. I need to relocate the wastegate.

BTW this was made THROUGH 3 inch CRUSH bent exhaust WITH A CAT

what no video? ???


trq seems kinda low for a high hp motor... ? i was expecting 300+ tq? wait wait, 1.6 or 1.8?

Re: Dynoed my dads car @ 17 psi
 

Wow. That's darn good. We need some more pics/vids. :y

Re: Dynoed my dads car @ 17 psi
 

Like i said, its spinning the tires bad, Its a 2liter with a type r crank (reason for lower torque) but it would just spin them on the dyno so thats why too. just read what i wrote.

Re: Dynoed my dads car @ 17 psi
 

i read it, thats why i asked. wheel spin looks to happen later in the curve (from the "flat then spike" you mentioned).

2.0 i thought would be way higher..

what gear, 4th? what trans?

Re: Dynoed my dads car @ 17 psi
 

cool man, mayb e dyno with the slicks would help the wheelspin problem?

Re: Dynoed my dads car @ 17 psi
 

this thread would be tits with a video :y

Re: Dynoed my dads car @ 17 psi
 

cant even read the freakin sheet

Re: Dynoed my dads car @ 17 psi
 

it was 3rd, and I did not want to stress the motor and run 4th gear on the dyno, thats how headgaskets get blown, its almost like running a fat 5th gear pull.. We blew the race car's headgasket up doing 4th gear pulls. the torque is about right for a 2 liter. @ 17 psi.. It also had 6 month old gas in it so we did not want to push it any harder. maybe in a couple weeks i'll have my dad go lay down a 500+ on pump. but the goal was 450 and we hit it on the 4th pull.

Re: Dynoed my dads car @ 17 psi
 

definatly need to dyno that bad boy 1:1 gear ratio

Re: Dynoed my dads car @ 17 psi
 

If you manage to blow an engine on a 4th gear roller pull, that engine was never meant to be anyway.
Hell an engine that blows on a quarter mile run (which is considerably longer than most dyno pulls) is definitely poorly built.

Re: Dynoed my dads car @ 17 psi
 

there is a lot more cylinder pressure lugging the engine through 4th on a load dyno, than bangin gears at high rpm

Re: Dynoed my dads car @ 17 psi
 

badass numbers, whats your dad say?? :S

Re: Dynoed my dads car @ 17 psi
 

exactly, its way different then on the road. the dyno rollers are 2000lbs each. thats like trying to move a 4000lb car. when the 4dr only weighs 2200

Re: Dynoed my dads car @ 17 psi
 

even still the tires probably would hold in 4th. that they didnt in 3rd is not a surprise.

Re: Dynoed my dads car @ 17 psi
 

Lookin good Josh... I'm gonna have to come kick it soon and check it out, and not be a flake like the last couple times...

Re: Dynoed my dads car @ 17 psi
 

Wish I was a baller.

Re: Dynoed my dads car @ 17 psi
 

great numbers. cant wait to get dynoed, just need to find one that supports more than 299ps

Re: Dynoed my dads car @ 17 psi
 

Wish I was a little bit taller, wish I had a girl If I did I would call her

Re: Dynoed my dads car @ 17 psi
 

I know for sure it would hold in 4th. but i'm not going to stress the motor like that for some numbers to impress someone. I might hit up the dyno pack and finish the tuning there.

Re: Dynoed my dads car @ 17 psi
 

trap speeds speak. dont need a dyno if you can produce good trap speeds

Re: Dynoed my dads car @ 17 psi
 

good job. great numbers.

why does he have to test 1:1??? HP doesn't care about the gear your in unless your testing on a dynojet which has shitty inertia compensation.

stess the motor more???? do you mean build up to much heat?? dyno's do no stress motors because the motor is what creates all the load. the dyno is just the resistance to the load the motor is producing.

Re: Dynoed my dads car @ 17 psi
 

bahaha

we got another turbod16 engineer here :1 :1 :1

i love laughing. keep it up trickeng

Re: Dynoed my dads car @ 17 psi
 

You really really need to know what you are talking about first.

Re: Dynoed my dads car @ 17 psi
 

I'm sorry, what motor is this?

Re: Dynoed my dads car @ 17 psi
 

sleeved 2liter GSR.

Re: Dynoed my dads car @ 17 psi
 

Very nice. What kind of sleeves are you running?

Where can I see your setup?

Re: Dynoed my dads car @ 17 psi
 

Re: Dynoed my dads car @ 17 psi
 

lol

your T fitting break off yet?

Re: Dynoed my dads car @ 17 psi
 

lol no

Re: Dynoed my dads car @ 17 psi
 

What did your moms car dyno at?

Re: Dynoed my dads car @ 17 psi
 

how bout posting pics of the car at least ???

Re: Dynoed my dads car @ 17 psi
 

Damn...old school Skeelo right there...thought nobody even knew who that was anymore ;D

Re: Dynoed my dads car @ 17 psi
 

Re: Dynoed my dads car @ 17 psi
 

you just showed the world wide web you know ---- all, good job :1

Re: Dynoed my dads car @ 17 psi
 

are you implying that no matter what gear you dyno in you will get the same numbers? ???

Re: Dynoed my dads car @ 17 psi
 

Your engine doesn't magically grow volumetric efficiency when you put it on a dyno.
Right, you have more heat buildup in the combustion chambers and more chance of detonation when the load is high but I haven't really seen any chassis dynos capable of holding any kind of load. You usually just get tire and/or cooling problems if you try to hold a steady load on a chassis dyno.
I tend to map my engines so they can survive fifth gear at full throttle uphill without detonating.

Re: Dynoed my dads car @ 17 psi
 

i want to see video of said car spining the tires on the dyno ::)

ive personally witnessed 700/700+ whp/wtq dyno runs and they dont spin the tires.


the ONLY way i see the tires spinning with that car is if you have bicycle tires or they guys that hooked up the car to the dyno used a jack to lift the car up so the contact patch was small :S


still, its pretty impressive the #'s you guys put down, i just doubt the tire spin store

Re: Dynoed my dads car @ 17 psi
 

I've seen a 400whp car spin the tires on a dyno, that was simply because it wasn't tied down properly. The guys in the shop had never dynoed a car that needed to be tied down so there was nothing in their floor to strap the car to.

Re: Dynoed my dads car @ 17 psi
 

never dyno'd a car that needed to be tied down :l ::)

yea, well, i dont know what dyno that one is, but i wouldnt ever go to that place, even if i had a moped :3

but you did prove part of my point, it was the guys that run the dyno shop that cause that to happen.

a properly setup car on a dyno will not spin the tires unless its just got a ton of power, like 1000 whp.

do i need to direct you to the TT Buick Regal that put up a smoke show on the dyno from spinning the tires??? im sure you guys have seen that and i seriously doubt the car being talked about in this thread is anywhere near the level of power that Regal was.
