Just installed a Blitz compressor system on an xA. Also installed was a Blitz sus intake, and Nur exhaust. No baseline was done. but it only made 105 whp on the dyno. since most baseline at 85-90 whp. this is weak. $3,500 for 15 hp. not a good investment.

The AF is completely lean too. it is like 18 :1 from 1000 to 2000. the compressor engages at 2k, and the af drops to 14.9 ish. stays that lean till 5200 where it gets a little richer towards redline. final is 12.9 ish around redline. still way too lean. ( well, it didn't ping, so that's a plus)

Definitely needs a better fuel computer, more injector, and better spark plugs.

Oh yeah, the car still had a full tank of 87, the kit recommends 91. there was no audible pinging, but the knock sensor is more acute than a stethoscope. it may have been knocking a little, and pulling back timing.

But anyway, the compressor system is definitely not worth the money in my opinion.

ouch.

Damn. That option just got thrown out the window.

 

Did the kit come with the upgraded ECU?

i wouldn't call it an ecu. it's a piggyback unit that splices into the factory harness. it simply increases the amount of fuel delivered so it doesn't run super lean ( although it does anyway).

the over all quality of the kit is top notch. every bracket, spacer, bolt, belt and nut fit perfectly with no modifications. the instructions were great.

however, the power is definetly lacking.

if the kit was around 2k rather than 3500 msrp , it would be a better buy,.

 

Thanks for the first hand info! I've been waiting for someone on this forum to hit us up with a real 411 on the blitz. The one really cool thing about the Blitz SC is the magnetic clutch. I think it's patented so will probably be lacking in any more powerful alternatives that come along.

 

yeah the clutch is pretty cool . it can activate the supercharger at 25 50 or 75 percent throttle.

there is also an off switch. but, with the switch in the offf position, it made 70 whp. far less because the air is being sucked through the blower, and the extra parasitic drag to spin the extra pulleys.

no difference in peak hp with the switch in the lo, med, or high position.

 

See.....this is why I'm waiting. Oh......and because I have no money.

Thanks for the info. Tired of hearing info from people that either don't have the kits......or are trying to sell them.

thanks for the update

 

can you pease tell me what other modifications you have done with the car ex: upgraded headers and exhaust? what diameter is the exhaust pipe? cause if you still have the stock ones, then you might actually be hindering the performance and not using the charger to its full potential.

 

Dont verone got a blitz unit on the Longo bus?.. whats he say about it???

 

All that money for far less hp than you can get from a 35 shot of nitrous . That's just sad.....very sad . I'll keep juicing until the EL kit or the Rev Hard kit comes out :D .

 

Wow! After three posts you got the Blitz SC, sheesh! That's too bad, I hope you don't feel too robbed. Not too many regular drivers - let alone crazy mod heads can drop that much just for the experience of it, you are truly barve...and rich and you drive the xA (I didn't know it was available for the xA too...!)

We've seen pix of it in the xB ---- Any pictures?

So, is it loud? Are you on an auto or manny tranny? How much did you spend on your experiment (install,etc...?) Do you really think it sux that bad and were there any numbers from Blitz before you did the install that you can all them on because the mis-represented the item? Blitz usually has a good rep, no?

Let's hope more competition brings lower prices to our niche. I really like the idea of the Blitz SC, I guess I still do :sad:

Hey Drew! Were your experiences similar on the xB with SC? It sounded like you were more satisfied with it... :oops:

 

total money spent so far $0. it wasn't my car. (and i'm glad it wasn't)

the exaust is stock, only a blitz nur axle back. it would definetly make more power with a bigger pipe, and no cat. but originally the kit is designed to work well with a completely stock car.

the car is a 5 spd. and the blower isn't that loud. you can hear it working, but it's not like all you hear is an annoying whine.

i believe blitz claims 20-30 hp. which isnt too bad considering my results. like i said, the car still had the stock plugs and 87 octane. in the instruction manual, blitz recommends going with colder iridium plugs and 91 octane. while these two may not make a huge difference in power, it would go a long way to make the operation safer.

don't get me wrong, i have blitz products on my car, i like blitz, and will continue to buy blitz. just not the supercharger. well, maybe. the owner of the car may go with the plugs, a new exhaust, header, and a SAFCII. this will definetly help. after this, if the car makes the power it should, it may be worthwhile. but for now, i still think that it is a lot of money for too little hp.

oh yeah, one other thing to note. the boost pressure of the kit is 4.5 psi, and around 5500rpm, the pressure drops to around 2-3 psi. (small blower)

 

Did you do the install yourself? Was it difficult? Does the drop in PSI mean the SC actually robs power making it necessary to aperate it at lesst 25% on the dial? Interesting, it sounds like it would be a great kit if the kinks got worked out even if the boost is not as substantial.

So, can any help to the ride be felt?
Not head snapping back power but any kind of gain in pick-up?
Ummm, what did you mean by safer operation with changing plugs and higher octane, is it really unsafe to run 87 with lower grade plugs?

Was there a big fat warning that it was not CARB approved..? :D

Thanks for the info, man!

yep, did the install my self. (mechanic by trade, simple for me, may not be for beginners)
the boost drop does flatten out the power curve a little, but not too much.

running the car on 87 and with stock plugs may cause detonation under heavy load. ie, ac on, hot weather, up hill, big loads. on the dyno, it didn't ping, but that's minimal load, and with a huge fan on the radiator, and intake.

i didn't drive the car on the street, so i can't say how it feels like, (damn).

 

Sounds disappointing. Why did you use 87 octane though? Maybe the engine started pining, and the ECU is falling back to the "Tiajuana sh*t gas" program. If I were you I would run through 2 tanks of premium gas and try again.

Also, what dyno are you using? Any dyno charts?

 

jeeeez....

my car dynoed at 103.6 with just an intake...

now with my headers and with my soon to be installe exhaust, i should be at least 115 to the wheels i would figure

something must be really funky with that setup, i hope they work it out since blitz usually makes top notch stuff!!

any pics of the set up?

 

Wow that hella sucks... Blitz was my number 1 choice. Now its up to Revhard, E.l. Prototypes, Stafford, and scioned.com. I'm choosing the one with the most power, I don't care about drivability.

 

unless i can get at least an 150WHP, it's not worthed

$4000, thats merely 1/3 the price of the car for a slight boost in performance


i'll keep mine as a cruise, just IMO!
