I peeled out moving like 2 k in first then put clucth in reved and dumped the clucth started to spin and I got kinda like a clunking wheel hop but clunking i mean like repedeatly till I got traction. I was told bye a friend on mine (The Guy that this nopistons name belongs to) it could be the diff mount?



One more thing I am getting a hesitation after 3800 all the way to redline he also told me that if it is not my cats that are cloged it could be dirty secondary fuel injectors. any help would be appreciated

3800 hesitation is a bad ground on the firewall for the secondary injectors. yeah that clunking is most likely your diff mount.

You probably have a 6 port actuation problem from 3800 and up if it's not the fuel injectors causing the steady hesitation.



Yeah a clunk is usually a front diff mount so best bet is to inspect it before going any further..

That does not sound like a bad diff mount to me......It sounds like your tires were bitting for traction. When you dump the clutch sometimes the tires will jump up and down. I think this can be made better by taking a look at your alignment, shocks and bushings. The diff mount could be a problem but the normal Clunk when taking off normally that is caused by the diff mount is not the problem here.



What Size and kind of tires/wheels you using in the rear and what kind of suspension?

3800rpm hesitation, if it hesistates the entire time from 3800rpm and up then it is a secondary fuel injector problem, possibly clogged or dirty.



If the clunking was while your wheels were spinning that is wheel hop. There are many ways this can possibly be solved. New suspension, new mounts, different tires, more traction increasing suspension pieces, a pinion snub, and many other possibilities have been tested.



Wheel hop isn't healthy for the drivetrain, it will wear out bushings and mounts and can lead to rear diff failure if exposed to wheel hop repeatedly due to such abuse.



It can be caused by what the tires compound is, the tires sidewall flexibility, the tires traction abilities, the tire size, multiple aspects of a tire can cause this.

That sound is usualy an indication of the front diff mount - they aren't known for lasting forever..

One solid "clunk" is indicative of a mount.



Continuous "clunk, clunk, clunk" while spinning the tires is wheel hop.

again another reason not to leave your nopistons account loged on at a friends house. "I got hijacked" LOL



His car has a surging effect, at 3800 the car feels like a slap in the face then it takes 10 years to rev up thourgh the rest of the power band. Car pulls beautifully in any gear under 3800 but if you try to rev it out it bites.



Car has an auidible clack in turns like slow parking lot turns and when the brakes are taped it also goes clack ??? have no idea what that is. And I think Technics is right his car did do that an wet pavement he tried to peel out after he was rolling bye reving and droping the clucth.
