The Vortech uses a single Xtra injector to provide the additional fuel for the S/C. With my past experience with a Vortech kit mine failed causing detonation and eventually among other things a complete failure. Would it not make more sense to replace all injectors rather than relying on the single unit provided with the kit? Actually would that even work with the provided engine management unit? Also why does Vortech use FMIC's on other kits and not on the S2000?

 

Here's my take on it:
You can't always apply "past" Vortech experience to the S2000. Only the '04s and newer cars that a Vortech kit is built for has the extra injector mounted in the aftercooler. They don't need to replace the stock injectors because the kit already boosts the fuel pressure proportional to rpm. The kit also alters timing to some extent as an additional safeguard. Furthermore, simply having the intercooler adds another aspect of insurance. If the extra injector failed, the system would still function like the kits for pre-'04 cars where there is no extra injector.
As for a FMIC not being part of the kit, I think it was a matter of packaging and cost. The system works just fine with the air/water intercooler. If the owner wants bling, they can elect to spend the extra money to do so as some owner's have already done.
For myself, the Vortech kit on my MY'00 has been working extremely well for nearly 2 years with no tuning and no additional parts. It's been tremendously successful so far. I think Vortech did a great job putting this thing together.

 

well, except for the damn belt tensioner location

 

Well, OK, I'll concede to this point. However, I must point out that after the initial 400 miles tightening and over 1.5 years and almost 20K miles later, I have not had to tighten it since. It's a backwards design and a bit goofy to actually tighten, but I must admit that mine has held up well.

 

I'll agree with you on this one. I never had to retighten mine after the initial tightening check-up. but its just that one time that you get under the car that stresses you out for the whole entire year

 

I'll def have to agree with xviper in his first post ...

 

I don't understand why vortech doesn't just invest in the emanage and sell that with the kit instead of the split sec timing unit.

The emanage would be used to correct the fuel management and provide timing control.


As for the belt tensioner, my bolt snapped. so currenlty I am waiting for the snow to melt so I can take off the entire supercharger housing, and send it the plate to vortech to be fixed... then put on my turbo

 

Probably because the E-manage's Timing control is not as effective as the Split Second unit.

 

True, the splitsec does wire into the crank sensor (+/- 0.1 degree), but +/- 1 degree is not bad with the emanage.

I think it's interesting that vortech wants to make sure the timing is "PERFECT", but does nothing more than slap on an FMU and high volume fuel pump for fuel management. Improper timing can be fixed by richening the a/f ratio, but poor fueling will not be fixed by proper timing.

 

While I'm not going to defend the FMU as the only means of fuel enrichment, I will say the E-manage's Timing control is shotty at best. I had to remove 10+ degrees of timing in RPM ranges well below boost to eliminate detonation. The split second box is cheaper, and more effective than the Greddy unit at timing control.

If I was going to re-do my Vortech/e-manage combination again, I'd seriously consider the Split Second FTC-1 with an aux injector and FMU.
