I'm going to order one or the other her in the next 2 weeks so I need to start getting some advice on which the better route for more solid power would be

What do you all think?

Here is the link for the Harrop TVS Supercharger

and here is ZZP Twin Charge

poll?

TVS ALL THE WAY

 

probably the tvs. I have not heard good or bad from zzp's twincharge kit but only good for the tvs

 

i've felt first hand what a safe/mild tune does on a tvs w/ supporting mods injection and head work. and its pleanty fast enough for the money. not to mention it has another tune that is just sick.

 

poll is up

 

what about hahn stage 5?

 

No Hahn

 

yo hahn?

 

twin charge

 

between these two, i say TVS. in general i would just go straight turbo IMO

 

tvs.

 

This is gonna be close. I don't want a straight turbo just an FYI. I Love the S/C's

 

tvs just seems to be more reliable and an easier install. plus cheaper.
ur gonna need or want to have full exhaust when u do either.

 

Check mark for the full exhaust.

 

he has a full 3" exhaust with a 3" downpipe if im not mistake..... not sure about header

 

wat kind of headers are u running

 

me? stock lol........ im done modding for a long time

 

no the op

 

Vibrant

 

just so you know on the twincharge kit, the SC has a larger than stock pulley . its not really doing anything but help spool a little bit but it will also raise intake air temp. and with a properly sized turbo you can have great spool and be very efficient

 

^^^ hmmmm.....did not know that. That's why I love this site lol.

 

All turbo FTMFW! Hahn... (cough, cough)

 

the head on my car is factory issue, aside from valve springs


so, you got to feel a 340+ whp bolt on car

 

Not to be biased, but I would say to go with a tvs. The tvs has a way broader spectrum of what you can do with the car and how much power you actually want to run. The zzp kit is great for power, but once it's done..., well it's done. There is no scaling down of power, or room to improve. I'm not knocking the first person, or second that decided to have it done, but I think the problem with the first installed kit came there. Don't take me as knocking the company for the work they did..., they even offered to fix things but there isn't much room for improvement as they feel they've constructed the ultimate kit.

 

well you had to do some work to get those spring in there right?

and yeah, that in a cobalt...hauls ass
