No... Raise your tp to 40psi, and tape up the huge gapping hole Genpu has for a grill and you would hit 150ish

My stock, 1998 chevy s-10 ls tops out at 140. You's shit B brokes essay.......

shift to 6th gear next time.

[tmmueller]

speaking of gears, some cars actually top out in a lower gear than 6th. Read that somewhere before. Drop it in 6th and it's just to tall to pull anymore. Maybe redlining in 5th gives you max velocity. Not sure if that's a factor with our cars or not, just a thought.

Our little turbo won't let you hit top speed @5th gear cuz its only good up to 5.5k rpm.

tip - most common leak

[Postulio4joo]

I was able to hit 151 on my gps and 155 on my speedometer on just a intake alone. I drive a 2010 so i think you either got a lemon or you gotta lose some weight.

[MS33SM]

Enable Vtec to hit 155. Without it your power peaks at 5500 rpm. Everyone knows torque is only useful above 7000rpm.

It is a well known fact that you will be slow until you donate. Simple $10 fix. There ya go.

[fishin53]

yea I hit 140 the car was stock when I did it also you just need to grow a pair

[ms3brendan]

I hit 143 when I was stage 2.. Car still pulls surprisingly hard after 130..

[ztnedman1]

I also hit 143 but that was stock and was running out of mexican realestate. Still had some left in her, it was just taking forever.

My last car would top out at 100 mph in 3rd gear. When it shifted into 4th(and final) gear, it would start to slow down, despite having my foot to the floor.

Haven't had the 7 out for a top speed run yet, but I have had it near 100 mph a couple times.

Your car is definitely fucked up if it tops out at 138mph. I would bring that bitch back to the dealer and make the service advisor take a top speed run with you.

My car hit 155mph stock. Took a bit, but it would do it. With bolt ons, it hit 155mph with ease. With the 3076R, I was raping M3's upstairs.

MS3 feels surprisingly good upstairs (probably because it's fat, at 3330lbs). Only thing that sucked was the driver's side mirror started shaking violently past 150mph. After a few minutes I thought for sure it would fly off. It didn't. Also the once firm feeling stock suspension will all of a sudden feel kinda rubbery at 155mph.

Wut? No VTAKKKK? How to getz quick thingzzzz NOA??

If you're woried about it?, take it to the dealership and have a boost leak test done. You may have a small leak somewhere
