Supercharger stutter

Recommended Posts

Now this is gonna sound strange, and its really directed at those with TTE superchargers.

Mines fitted and working perfectly, however, in high gears 3rd 4th etc at low revs, between 2000 and 3000rpm when i hit the accelerator the engine stutters, at exactly 3100rpm the stutter goes and engine flies.

Ive tested it in hot conditions, cold conditions, the plugs and coils are fine! Someone suggested that the vacuum created in the inlet manifold under heavy load causes probs, others have said too lean mixture!! Im lost now!

Has anyone else had similar experiences with supercharged engine.

Any ideas?

One lexus chap did say 'we give you six gears, why dont you use them!!" :lol:

not a very helpfull reply.....i would say its more to do with the vacume thats created.....any engine will get bogged down trying to floor it in low speed high gear situations,the problem ist there is not enough momentum in the engine to cope with the increased air/fuel.....so stumbles untill the momentum builds up in the crank/flywheel

Yes - agreed.

Power delivery isn't always smooth ...

I was thinking it's maybe something to do with the bypass valve.

But like you say,

reassuring to know it's the same for everyone :yes:
