Top speed?

Is the top speed for a syclone really 126? What happens when the speedo is pegged, but you are still accelerating? What's the deal?

The fuel pump will cut out.

This is limited by the chip. If you have an aftermarket chip, this is usually disabled, and it'll go faster.

You're going faster than the speedo registers.

This will help you determine how fast you're really going based upon your RPM's.

Hope this helps.

Re: Top speed?

Our factory stock chip doesn't cut fuel, it limits boost to the base boost of 8-9 psi. If I had to guess a Stock Syclone will do low 130's with boost cut, but it will take a while past 126...

i had mine at over 5k in forth gear a couple of times. probably 155 to 170 mph. i didn't have a stock chip, or a stock anything else for that matter :)

Yup on my way home from picking mine up in indiana, I raced a 1g dsm on the freeway in des moines and hit boost cut, I was dead even with him. At the light on the off ramp he told me he let off @ 135, and the usual "wow that S-10 is fast!"

Re: Top speed?

well ...there wasn't really much traffic out... would have probably gone faster but there was a passenger in the truck and he presented a bad aerodynamic drag trying to climb out the window...

I've buried my Ty past 120, not too far past, but even at that speed, I felt like I was driving a shopping cart; it was starting to drift pretty well. I can imagine how squirrely it is at 155-170!

Re: Top speed?

Will Stevenson and myself ran my truck up to 140mph, on 9psi boost (wastegate was stuck partial open), mostly stock truck minus chip.

Had it recorded on diacom at one time. In fact it was on the way to the 98 syty nats between denver and KC.

Aerodynamics bricks + 140mph = nervous in corn fields.

Re: Top speed?

actually... it wasn't that bad i was TOLD. the hood buffeted a lot but it squatted and screamed. remember what my truck was though. it was not anywhere close to stock engine or suspension. the thing ran almost 140 in the quarter. read on the web about the autobahb syclone. probably the same as mine.

oh... and remember... i wasn't driving it. my friend was. no 165 mph plus for this ol boy...

i've had my blazer probably up to 150-160, 5700 rpm in 5th bouncing off the rev limiter. Sure does get real light in the front end, quite scary riding in a brick traveling that fast. i can't even imagine with stock ride height, shocks.

Re: Top speed?

... and the bitch was still accelerating and pullin HARD i was told. fast reading showed it was true. although the IC temp was going up, but it was tuned to run rich so it was OK. i ran mine up to about 6 grand in first so if it had hit that in 4th i wonder how fast it would have been going...

now that markie mark has it why don't we ask him to run it through one of those radar things that tell you how fast you are going at 6 grand in 4th gear and have someone take a pic of it. we'll find out two things.

1... how fast it will really go

and 2... how big marks balls are... you up for it mark?

i think it will top out about 170 to 175 with one person in the truck if mark isn't carrying any extra weight and goes to the bathroom first so he don't poop his pants... :)

Re: Top speed?

Dabney Crump did the legal road race in Navada a few years ago ...
Although not toaly stock it was stock-ish motor, Stock turbo, STock tranny,
He and Sean hit 151mph at a calibrated radar check point...

I have had my Ty to 140 (by RPM) and it gets rather scary.....

With the HP that truck has it has the ability to go faster (at least theorectically)
He will probably run out gearing before being wind limited. Approx 185 mph (if the TC is lock) would be about 6K in 4th, I think it could be done, if the suspension, aerodynamic and the drivers is upto it. A s-10 might be all over the road at that speed...

Re: Top speed?

hey dave

i might not be wind limited, but it will definitely be driver limited if i'm driving it. no 185 mph for this kid unless it's a ferrari, porsch, zo6, viper or something else built for high speed. somehow i don't think it would be that cool of a ride in a sy. mine got to 120 so fast and did it so easily that it never seemed like a big deal until you noticed that the other cars were standin still. i was always scared of someone pullin out of somewhere... if i lived in utah or somewhere out west i would think drivin fast would be fun. but where i live the roads are so trash with potholes i was always worried about bending a rim
