Bill this was on the 20g right that you offer with your kit? I don't know the cost of the turbo (20g) but this new turbo, the RR500 from Helix, seems to kick the crap out of the 20g on the mid range, spool just as fast and offer almost "green" like top end.

Also is a ton cheaper than a comparable 20g. May be something to include in your kit to keep costs down. I have been following this from my subaru days.

Also what are you using for boost controller? It this part of the overall kit price as well?

Thanks Bill...we wait anxiously for the final product.

 

sooo iguess that means faster than 140 right? would that break our needles or would we just have to approximate after 140? iguees theres a new tach on our shopping list also

 

Yes, all these performances were with 20G. We love these units! Thanks for the input.

No boost controller needed...the turbocharger makes the boost pressure we designate.

 

Thanks Bill. Are you guys using the stock 2.4 MAP sensor? Or a Gm 3 bar sensor?

 

In the Stage II, standard 2.4 sensor.

 

Thanks again Sir. I assume then that Stage III and IV uses an LSJ or GM 3 bar? (You can PM me if you don't want to reveal proprietary info) just curious.

 

Bill,

One thing that really bothers me about those dynos is that i drive on the freeway at 3K, that would be hitting full boost all the times... from those dynos its looks like drivablity and gas milage will suffer greatly. This also plays into powerband, with such small increases at higher rpms, this will have everyone short shifting like a ****.

What i would really like to see (and maybe people will disagree) is boost moved back to 3200-3500rpm (slower spool?) and full boost around 5k, that way the huge flat spot in the power band would be around 6k (more around where we would shift). example: stock 2.4L SRT-4

this would allow our cars to still be streetable around 2k-3k with stock-ish EPA numbers

 

Great insight,alot of peaple will for sure want to keep the everyday driability of their car

 

yeah i dont wanna keep hearing my BOV when i am pulling into my gf driveway or when i am driving up to a nice restaurant lol..

 

Gentlemen! Unless you plan to cruise at wide open throttle, full boost, what you see on the dyno graphs has nothing at all to do with daily use at cruise and otherwise!

This is the true promise of turbocharging....a docile, economical engine at low throttle openings, and all the power you need at full throttle, with a nearly infinite selection of power levels at your command in between. We like to call it 'power on demand'...it's like having an infinitely variable supercharger, controlled by your right foot!

You might be surprised to find that much smaller turbos (such as seen on SRT-4) actually produce even less mileage than one of our systems, for those diminutive stock turbos just spool too quickly. We have testimonials from customers whose mileage has INCREASED when they fit one of our larger turbos!

As a final note, we've been getting numerous reports from our Solstice customers that their mileage has increased since the installation of our turbosystem. Efficiency seems to be the reason here...the turbo is recovering otherwise wasted energy, and they just don't need to use so much throttle for acceleration as they did before the turbo.

 

actually on the soltice forums I seen som of them did get better gas milage

 

OMG COME ON! ENOUGH FOREPLAY! My ***** are getting blue here SOMEONE GET DARKLORD A VIDEO CAMERA!

 

 

So maybe half of my question was answered by a post saying that they did a 2.2 sunfire but will a 2.2 cobalt kit be available?

 

well I just went to the web site it looks like one is in progress

 

you've mentioned everything in the stage 2 turbo

whats included for the stage 1

a student like me cannot afford a stg2 right now, however i'd like the power for a stg1.. any pricing ideas

 

let me get this straight you dont like the sound of a blow off valve? or do you have an automatic and dont want that to be obvious. cause i never get tired of hearing badass sounds on my car. lol

 

good question!

 

Stage 1 intriques me, due to what I want and affordability

 

You've never driven in oakland before.

Bill, i've been reading about your works in mags for years so please understand that this newb doesnt mean any bit of offence. That said, can you comment on the powerband question? It seems like the most gains are in the pre-4k range, this is the same issue we have without the turbo, we have nice power on the low-end, we suffer on the top-end. It doesnt look like this turbo kit will help that just add higher numbers. What i mean by moving the spool/boost back was if the turbo "kicked in" later, we'd keep the same traction levels we have now at lower rpms, and have more power at the top without the "table top" effect at shift. Maybe you have a stage with a tubine swap that better suits what im looking for?

Also on the gas milage, maybe the prototype guy can do some runs for us at different speeds? (65@~2.5k?/ 80@~3k?) and give us numbers?

 

also, not only am i curious about stage 1 (along with the other members) but what post-turbo developement can we expect.

i know its early because you've only just completed the turbo, but at there going to be any extras such as the Stg2,3,4,5 that are available for the SC?

the bottom line is that i dont wanna get a turbo and be stuck at 240hp which the s/c are hitting 294 (highest hp rating as of a few days ago- check out the 2.0 section)

 

there are numerous people on here questioning what stage 1 will be like...and i dont think there is a stage 1 ...from what ive taken in its starts off at stage 2....not many cars have "stage 1" upgrades.....i would assume stage 2 meant it was the stock version with turbo.....dunno though thats just my thought.,..itd be cool if there was a stage 1 though....cheaper and a nice starting point...

 

no adding the turbo will not make it go faster than 140....in terms it could.....but the car isnt aerodynamically designed to go faster than 140....maybe just a bit but it would be pushing it....the limiter will more than likely be kept at 140.....

 

ummm... mike... our car is the same design as the ss s/c and it goes faster than 140

 

and if there isnt a stg 1, it'd just be smarter to exchange your 2.4 in for a 2.0 and then use the remaining 1500 dollars to buy stage upgrades for the 2.0, resulting in numbers near 300..

therefore, i cannot see how hanh will make a profit by pricing their turbo this high.. it just doesnt make any sense that way

plus not only would you get a 2.0 sc, you'd also get bigger rims, better suspension and struts, and a body kit..
