Just want to gather peoples opinions on forced induction.
If YOU were going F/I and spending YOUR OWN MONEY, which system would you choose.
Think about power, reliability, drivability, lagality, cost.

Vortech Supercharger
ATI Procharger
Stillen Supercharger
HKS Rotrex Supercharger
Greddy Twin Turbo
Power Enterprise Twin Turbo
APS Twin Turbo

Don't just jump on the bandwagon, this is your car and your money.

 

A supercharger system doesn't make any sense to me. The TT's have a better powerband and higher maximum potential, so why get a supercharger? Sure, the TT is more expensive, but anyone with a passion for modding cars knows they'll be spending a lot of money no matter what. Out of the turbo kits I like the APS the best.

 

As JeffesonM stated, the turbo has a much better powerband, much less parasitic loss, and much higher potential power.

The APS turbo kit has a much higher quality and attention to detail than the other kits, and uses better turbos.

I think the answer is clear. At this point, I would choose an APS twin turbo.

 

BU-BUMP!!!

 

The APS sysyem is clearly superior in the use of it's components, design and engineering. The company also has a solid reputation. Still, for the power level they are marketing their kit at, I believe an internal upgrade is required for true reliability. It is for this reason alone that I went with the HKS supercharger. Equal quality and engineering, but designed to function at a somewhat lower power level and considerably safer on the stock internals.

 

Kinda strange.....HKS SC ....got so many votes when I dont think any one has done a review on it . And APS has any one reviewed it yet ? Reminds me of the hype about Dreamworks . Every one loved that one and couldnt wait to get there hands on a dream..lol..Not that HKS or APS arent going to be good products

 

No comparison, we never saw DW even on a real car and information was nearly a trickle. APS on the other hand has provided more info than "any" vendor out there. Vids and all.
Granted the marketing lit is a little "colorful" at times, but the info provides solid proof. Sorry there is no comparison. APS will rule.
Now wrt HKS , I don't doubt the quality , but the power comparisons between the TTs out there and the HKS system are apples to oranges. HKS .... way too expensive for the gains IMO.

 

wasnt saying any thing other than...alot of votes for some thing that no one has tried...thats all....lighten up

 

Sure I understand your point, just a discussion, not like I called you a d--ck or something, no agression intended.

 

BIZUMP!

 

Pardon my ignorance but ,huh?

 

Thats just a fancy "Bump".

 

GET THE APS.........take it from a guy who had a centrifical supercharger named Vortech..............Now that I have a turbo, there is no other type that compares to the pure power of a big azz turbo.

 

I really hope that APS offers a tuner kit.
They seem game.
The default kit's fuel control is great for <12 psi,
but if you need more (ie built block), custom fueling and timing is the way to fly. The work Phunk is doing seems veeeery interesting. HKS FCON has my attention now.

 

I'm curious to know why the APS is so wildly recommended compared to the PE kit. I think it's because APS has a presence around here--and I'm actually glad to see them get a return on their time investment in this forum.

But other than that, what specifically about the APS kit is superior to the PE kit? They seem very similar to me.

- I'd be willing to bet money that the turbos for both kits are sourced at the same location (in other words, the PE turbos look exactly like Garrett turbos to me). They look *extremely* similar.

- Both kits use internal wastegates.

- Both have a fuel return system and an FPR in the top of the fuel pump housing.

- The PE kit doesn't include the coolant fittings (although the turbos have inlets/outlets) but they are easy and inexpensive to add during installation.

- Both kits have a very nice and appropriately sized intercooler.

- Admittedly the PE kit doesn't include a BOV, presumably for CARB reasons (?) but it's easy to add.

- The PE kit has stainless steel manifolds whereas the APS manifolds are cast iron. This is a definite plus for APS, but something tells me that PE will change this very soon, so I'd bet that by the end of the year they'll both have cast manifolds.

- The APS kit comes with injectors and a pre-soldered harness. The PE kit comes with injectors that don't need a harness.

- The PE kit is typically used in conjunction with a TS reflash whereas the APS kit will require a map provided by a dealer. No end-user tuning comes with either kit.

When did u switch to turbo??? Ru talking bout ur super duty those r some insane numbers!!!!

 

I was wondering the same thing as zimbo. It seems to me that the APS and PE(assuming that they go with cast manifolds) kits are very similar in there design and high quality. What make the APS system worth all the extra money?

 

I'd go with vortech only because I have an automatic.

But turbo would have been my first pic.

 

I just read your questions and there are some obvious answers to your question relating to the cost difference though I admitt I'm not sure what the cost variance is between the 2 products.

Here's what I see as being the main differences between the 2 products, there may be other differences between the products, this is what comes to mind only.

1) The turbo exhaust manifols and turbo dumps are cast in the APS TT system to provide the best possible durability and performance.

2) The APS TT system has water cooled Dual ball bearing Garret turbos (capable of supporting mass air flow for 800 Horsepower) and a water cooled plumbing system which is not inexpensive to produce.

3) The stock fuel system in the APS TT system will support up to approx 12/13 PSI of turbo pressure (around 500 rear wheel horsepower) though we do of course recommend that the con rods are upgarded for this power level.

4) The APS TT system has a huge Bar and plate intercooler ( most efficient intercooler heat exchanger) and has equal length air ducting from the turbos to the intercooler to maximise intercooler performance................APS intercooler will provide a path to higher power by delivering lower charge air temperture at high boost pressure with minimal intercooler pressure drop at elevated power levels.

5) Mapable fuel, ignition, and turbo pressure capability.............this way the engine can be dyno tuned for optimum power and to take advantage of higher octane fuel where available.

None of the above suggests that other TT products are not great products............it just that the APS TT system has been designed and developed to cope with much higher power levels from day one

APS has taken a long term......... more considered approach to the high power that Z owners wil demand in the very near future.............the APS TT system offers a very real path to extreme power without needing to change the most expensive parts in the TT sysyem...........that's the dual ball bearing water cooled Garrett turbos and entire intercooler system

Thanks

For us Californians APS has committed to seek CARB approval, PE has outright said they will "not" seek a CARB EO (big mistake IMO). So PE has kind of made my choice even easier.

Also, Hint Hint , Peter , CARB is still very important to a large customer base in Cali, please keep up the pursuance , and that includes us G35 owners.
