Lets said that i am going on the highway ,and i am chillin on 5th gear and i punch it why it wont go past 5/5 rpm????? is this normal or i got a problem???

 

what the hell is 5/5 LOL....

 

5500 rpm?? i dunno man it should. exp if its turbo. i know alot of n/as dont have **** that high in 5th gear

 

well i punch my car in 5th gear and when it got to like 5500rpm it didnt want to go no more but my car was still pulling but somthing was not let in it past the freaking 5500rpm,

 

129 mph? that's it?

Maybe you have an N/A engine.

 

fuel cut?

and sean the S4's have a taller 5th. so he'd be doing faster at 5500 then you would. no idea what speed that is

 

NA engine in my 87 turbo II UMMMMMMMMMMMMMMMMM

 

no is not fuel cut

 

I believe that was only N/a's, and that all turbo cars have a 0.762 overdrive.

 

this happens if i start 5 gear and punch it i wont past 5500 rpm is like 120 some miles ,but if i start lower gears ,said 2nd up to 5th gear, wot all the way, i can easily get 150 mph

 

what???

so what you're saying is yiu cap out only if you hit it in fifth, but if you redline through all the gears, the problem doesn't exist?

 

you are probabbly just bogging the crap outa the engine if you are starting in 5th...

 

i still wont past 5500rpm when i get to 5 gear

 

then how do you hit 150 mph? pegging 8600 rpm in 4th gear?

 

i hit 140 like in 4 gear then 150 when hittin 5th but my **** wont past the freaking 5500rpm

 

140 in fourth is 7800 rpm. Don't rev your engine so high.
150 in 5th is 6400 rpm. Above where you say your problem is.
Unless, of course, your tires aren't close to stock sizing. Then, your speedo will be off anyways, so this thread is entirely moot.

Something here doesn't add up.

 

maybe maybe ,i will try to get my car up to 140 with some one in a another car at the same speed to see if my car is carzy

 

those # are calculation i can remember the rigth mph ,i will try tomorrow this to get the right numbers

 

i got some dunlop tire size 225-50-16

 

For starters, at that speed the speedo can't be considered accuarate. Most speedos read high, and as speed increases that error becomes significant.
Assuming you tyres have the same rolling diameter as stock, a real 150mph needs 6000rpm in 5th, so your speedo's probably off.
At 5500rpm in 5th you'll be doing ~137mph, which is only a little down on stock. It doesn't take much of a power loss (e.g. clogged cat) to lose 5-10mph off your top speed.
You haven't mentioned any mods, so I don't know how much power you should have.

 

maybe you were going up a hill or something and just didn't have the torque.. try doing it on a different road..

 

what is the max rpm on 5gear on a T2?

 

Yeah the speedo is junk. I was at an even speed with people who were claiming 140 on the straight at VIR while my speedo was barely pushing the 120 mark.

Also: what is the speed at redline (7000rpm) in 4th on a 1990 T2?

Also: My gearbox is j-spec, so my ratios might be screwy too.
