So guys, just got my car tuned, made 363 at ~11psi. Now the problem is, if i punch it into boost, at about 9-10psi, the front end shakes VERY violently and car red lines!! Now i cant figure out if its bad wheel hop, axles or trans?
its a built F23 tuned on AEM EMS.
Thanks.

lol come on man wheel spin/no traction

S1n1SteR

ok but then why would it redline?

Alfa Turbo

You ARE kidding, right?

If not... get ready is all I can say cuz' it's coming... lol

sanman000719

spinning wheels means no engine load anymore meaning free spin of the motor since there is no load equating to rpms's shotting through the roof meaning redline

S1n1SteR

haha dude i have a turbo ACCORD, i was born ready haha

i lowered tire pressure to 19 but that didnt help any at all. Btw, when i was at 5psi, making about 250whp, it did the same thing?

sanman000719

well yeah spinning tired at 250 will happen also you can either take the advice or not man but your soinning the tires is what it sounds like to me

_kiid

lmaoo yeahh your spinning! your at 360 duhhh lol
i was spinning making 240 lol

S1n1SteR

I really do hope its that cuz i just got my car back after a year and three motors and i dont want it to go down again

_kiid

i have friends spinning stock k20s lol n thats like 180whp

sanman000719

3 motors oh trust me i know that feeling first one was a rod/then 2 valves/then 8 valves lol/then went to a stock motor and ran all summer long at 498hp like it was nothing lol

_kiid

when you hit it going in to 4th gear it feels good right? no wheel spin?

S1n1SteR

yes sir! it does that even in fourth! heck boosting in fifth the car red lined for no reason soon as i got to 10lbs. sanman at least you got to feel 400+whp, i am at 362 on a dynojet and i barely feel 250 cuz after that...

sanman000719

what clutch are you on this might be the clutch fanning

Seraph0

Do you have a broken CV joint/axle?

sanman000719

a broken cv joint would be really noticable wouldnt it i mean all the power would be on 1 side causing it to pull to that side

S1n1SteR

CM stage 4 and Seraph0 i just got the car last night and i experienced this bs like an hour ago. wayy too cold in NY to check it right now but maybe ill get on it tomorrow. right now i am just trying to theoretically diagnose the issue.

sanman000719

well then hopefully its tire spin man clutch shouldnt be an issue

sleepencivic

sounds like the clutch slipping to me...what car? what tranny? cable or hydro clutch?

S1n1SteR

01 accord, f23 tran, not sure since my car has been through 3 of everything, literally!
wouldnt a slipping clutch cause a smell? also, would a bad clutch cause bad shakes? now these are not vibrations that i am talking about but SERIOUS shakes! like 20, 000V passing through kinda shakes!
i do have a quaife lsd in there too btw

boostedcivicsir

im wondering if the clutch is slipping myself.

S1n1SteR

but would a slipping clutch cause the whole entire front end of the car to shake soon as it starts getting boost?

boostedcivicsir

a cm stage 4 is sintered metal. one that couldnt hold the power in my car caused a shaking so bad in my car on the dyno, i broke an inner cv joint.

it was on a dyna pac, so there was no tire slippage.

if it were a bad cv, it would shake the whole time under acceleration, not necessarilly in boost also.

sanman000719

ya know i think i emember something like this in my car also when i wasunder WOT the car would shake badly, and it was determined it wasnt getting the fuel it needed this is why i went with -10, and the a1000 fuel system.

sleepencivic

log the runs and look back...might be the wrong clutch disk as well... not sure about the Fseries but there are several B-series that the earlier ones fit on the later ones splines but are a little loose and incorrect.
