ok im not really concerned about the rod knocking
or engine sounds
im concerned about shifting was that to soon to be shifting ??
today when i raced the celica i shifted above 5k and the engine seemed to love it so im guessing that 4k was way to low.. well anyways figured i would share my story![Big Grin](https://dodgeforum.com/forum/images/smilies/biggrin.gif)

he has::: udp, exhaust, header, Mugen chip, CAI, and thats about all i can think of right now

well the reason you lost is when you down shifted you probly took to much time to shift and gas. and when you down shift you got to think about how many rpms its going to raise you back up to so lets say you shifting at 7 grand every time when you shift it would drop to 4000 rpms sp thats 3000 rpm drop so if you where cruzing in 5th gear and was cruzing at 4000 rpms and down shifted you would already be at 7 grand and would be detrametal to the car. so you would have to be at 3000 rpms and shift then you would be safe. also your reline has a roll in the rpm drop # if you got a stock computer its low but if you all hooked up titaimum retaners etc. you can shift 8 grand so 4000 rpms and down shifting would be safe

so if you have a rod knock you can easyly check to see if its a wrist pin or rod know or nothing! what i do is start teh car let it warm up for a min or 2 and pull each spark plug wire off 1 at a time then plug it back in and go to the next what you want to do is listen to the knock when you pull the wire if it gets louder is most likly a wrist pin knock, if you pull it and it gets quiter(sometimes it only gets quite for a little and gets loud) its most likely a rod knock. the reasons for thhis is when it combusts in the clyinder and fires it pushs the space between the crand and rod so when you pull the wire, the sound gets quite bewcause theres no forces being exerted on the piston,there for its a rod knock, now wrist pin when you take the wire off and its not firing the pin and piston are no longer having the firing force pushed agiasnt the piston there for when the wire is pull it gets louder because it not pusing agasint the bronze bushing it tapping. i hope that helps. It always worked for me and every engine i rebuilt i was always right with that test. if nothing happens you could have a colapsed hydralic roller rocker and every tiem the valve returns it bangs angest the seat and hits the rocker and there for making that annoying tap. when you do the test you can use a long screwdriver to "listen" to the engine. and when you check to see if its a rod know listen to the car runing by the oil pan and rev it if the sound is realy lound at the bottom of the engine is mosy likly a rod knock. and if its you main bearings for the crank usaully the oil seals are leaking like crazy and you have crank walk withc is bad in and out play and pissobly up and down play(realy bad) people get crank walk from using to agresive clutch in there cars like a 6 puck race clutch, the pedal effort from that clutch is insane, you can admagine what presure you pushing on the crank when you push the pedal in. so if yoiu dont got a lot a power theres no need for 6 puck thats for major hp cars multi disk is the best way to go best sliping fetures, and the best for the crank bearings to avoid crank walk

The Civic has 125hp and 100ft lbs of torque. You can race anything. Go Karts have 5hp and people still race them. The SOHC has 140+, wheel Hp. Comparing with the DOHC wheel HPproves the SOHC is in the 140hp range.
A Dirt Bike against a Moped isn't a race, no way the mopeds 50cc's are gonna have a chance against 250cc. When you don'thave 2 vehicles with comparable power or Quarter Mile timesthen say its not a race.

retarded, you drive a neon with 132 horsepower, its not a race.

how does a sohc have stock 140+ hp???? when numbers to the crank r 132 stock???
The SOHC has 140+, wheel Hp.
The 426 Hemi is rated at 425hp, They did that on a Dyno thatwas only ratedtohandle 400hp, real world dyno's show 560hp at the crank on the Hemi.
Chrysler has a history of underrating their engines for insurrance and whatever their specific needs are at the time.
