Hey Every one ..

Finally I just bought a 2004 Ram HEMI slt 4x4 .. it has a 3.55 and 65000 km ..

any way its like a new one but the problem is its too damn slow .. it takes 10 seconds from 0 - 100 km .. and i dont think that stock hemis are like that ..

by the way i installed a custom spectre air filter and a flowmaster 40 series and a turndown and i took the cats off ..

after this mod it does a small backfire when it switch to third .. and i dont know if thats good ..

sorry if my language isnt perfect but i am saudi .. and i think that you are the only guys can help me .. because belive it or not iam the only guy that have a ram hemi where i live other than that they use it for companys .. i have a lot of friends have gmc sierras 4.8 and i was tellin them that i wil show them what hemi can do but now i am disapointed ..

 

give it a full tune up, replace spark plugs, EGR valve, and filters. Use all synthetic lubricants. Clean the throttle body and you should be good to go. You should smoke a 4.8 or 5.3 GM easily...

 

thank you very much ..

i will do exactly what you said .. i already have a check engine and i went to a mechanic and he said that the check engine is for the egr valve and i dont have to replace it ( i cleand it but it didnt work ) he said that it wont effect the car because its a heating sensor and we dont need it here in saudi arabia .. is that true ?? and does egr valve effects hp and torque ??

are you sure i can beat 5.3 easily with a 3.55 .. beacuse now i cant .. i hardly beat 4.8 and its just untill 150 km then they leave me back ( my ram is so bad at 3rd )

and im noticing that my oil pressure is not moving its in the half even if i go full throttle .. is that normal ??

 

An EGR CEL will effect performance, replace the valve and find a new mechanic.

If you want to race other trucks, then re-gear to at least 4.10s. But a 3.55 equipped Hemi QC 4x4 will still beat a 3.73 QC 4x4 GM if it's performing up to specs. Now if you are racing a significantly lighter truck, such as a regular cab or a 4x2, he will stomp you!

My oil gauge rarely moves from just a hint above half. But it wouldn't hurt to pick up a bottle of Seafoam and treat the crankcase, air intake and gas system while doing your full tune up and TB cleaning...

 

i think when i am ready i will go with the 4.56 .. and i forgot to say that my ram is a regular cab .. so i guess its worst than you think .. a regular cab and a 10 seconds is so slow ..

thanks alot ..

you did a big favor for me .. i dont know how to thank you but i wish i could return the favor some day ..

 

shoulda got the 5.9 lol jk back fire isnt really bad , its leftover fuel that hit the headers and backfire , you can really hear backfires if you have a open exhaust like a cutout hehe

 

How fast are these speeds in mph? There is a guy I work with who bought a chevy with the 6.0 last month who I school at least once a week after work. So you should be taking these 4.8's and 5.3's with no problem I would think.

 

welcome hemi 5.7 im from Egypt. i just need to tell you to take care coz i know u drivers in saudi are crazy and u drive so fast. so speed safe and dont street race coz i know the number of dead young guys who die coz of accidents. i think you should get a superchip and the 4.56 gears with an LSD. then you should do all the stuff hammerz told u to do and i think the check engine light is coz u took off ur cats.... trust me the gears are the most important mod and of course use 95 premium fuel its cheap at ur place ....cheers and enjoy ur ride

 

Supercharger?

 

I didn't catch that on my first read, good catch Ahmed.

Yeah, unless you do the non-fouler trick or install simulators, you will generate a CEL when removing the cats. However, unlike a CEL generated for the forward O2 sensors, which will adversely effect your A/F ratio, a CEL generated for the rearward is simply a warning light, and will not effect performance...
