In theory keeping the stock H/E in addition to the second one will yeild you better cooling results due to having more fluid with the 2. I don't know if it's possible with the newest and largest H/E but deff run both if you can.

 

meh I won't get into it. Replace the stock one with a griffin is the best thing to do but pricey. I'd run single pass w/ option B with just the stock + meth or same combo with the griffin.

 

i read that having two h/e is bad because hot air gets trapped between them and does nothing to cool the coolant in the stock h/e, so it defeats the purpose...and i would have to agree with what I read because it just makes sense.

I'll probably run an OTTP h/e with option b first, then add meth later.

 

So your convinced to go TVS?

 

I have it never was a problem. Me I'm not really for the number just to surprise evos and sti and have a power band that I can use on the road.

call eaton it's your boost use it when you need and I want it now.

 

290whp

 

Nah I havent been to the track yet, soon though! ANd right now I have the Vibrant header/dp and Hahn catback

 

im interested to here which one is getting better 1/4 mile times

 

I don't understand why people are so fixated on HP #'s for a DD car. A properly tuned TVS set up is going to make more power than you can put to the ground. That's all you need to know unless you enjoy buying new tires every summer! lol

 

link to said posts with actual evidence? i.e same set up comparisons with IAT logs.

 

Im on my phone at work so its hard to do this, but the link is in this thread back a couple pages either on page 2 or page 3, there are two tvs thread links, its in one of those threads

This is kind of why I'm leaning more towards the ottp stage 3 kit...this is a front wheel drive daily driven car and I feel the hahn turbo kit will be too much

 

sub'd

So really what are you trying to accomplish? Do you just want a quick DD or are you looking for something else? I think the comments in this thread are all good. It is true TVS = Great Powerband and Turbo = Higher Upgradability, Higher Numbers. IMHO either way you go, if you build well, and smart and custom tune it you will be happy with the setup. One thing I saw mentioned a few times were that to go Turbo it will be much more expensive. I would have to disagree with this only because if you piece together a kit yourself then easily you could walk away with a complete turbo kit for around 2500 less or more. I would love to go TVS but just because I personally like turbo's a bit more for 4bangers I would lean towards that . I think the decision is completely up to you though and if you have access to someone with a TVS and a person with a turbo swap you should ask for a ride; that should aid your decision. Good Luck though

 

Come on now Todd don't pick on us turbo guys! Seriously, though, if I had an SS/SC...I would do a TVS...Blower whine makes me blow my load...Plus the power band of the TVS is absolutely astonishing...

 

There is a lot of good information in this thread and comments and I can't believe it got this big but its a good discussion, let's keep it goin!

My original goal was 350hp, not nessesarily whp just hp.. I basically want a 12 second car that I can daily drive. I think anything faster then 12s on the street is too fast for the street, that's just my opinion.

So whether it be a 12.9 or mid 12s I don't care, I just want to hit 12s

they both can reach that hp and times. all comes down to money. and preference and how much of a swap you want to do. and what u want the most

 

Does that wot box work good?

Is that the one modern perf offers...? I thought bought picking one up

 

i love it and idk mine is from http://www.npcompleteperformance.com/wotbox

 

ya I think I want that and need to just get it lol

 

thread makes me want a tvs!

 

Ok so instead of running meth eventually, would a killer chiller be just as or more effective?

 

Well I finally just read through this whole thread... I am in the same position as most guys. I am wanting more than just GM stage 2 kit (or stock in other people situation). I have looked into OTTP stg.3 (TVS), M62 with a 2.6 and 60's, twin charged, and turbo kits. After reading a crap load of threads, PMing a million different members, I am leaning towards the OTTP stg.3 kit for a whole bunch of reasons. Number one it is a cheap(er) kit that most turbo kits and a twin charge kit, if you cooling for it, it will be reliable, There is always room to expand with a smaller pulley, easy to install, I heard great reviews on the customer service of OTTP, etc. For what I have researched with TVS is that it is most certainly possible to attain 350WHP on stock internals (you may need a customer tune though). This is my plan for the next month
-OTTP stg.3 -7200RPM, 3.0 pulley, stock torque management, 2 step plugs
-3" RAW intake
-LS4 Throttle body
-Option B
-Dual Pass
-Stg.2 rotated mounts
-Meth (on the next pay check)
-(I already have a CX racing H/E for cooling, and Hahn header, DP and catback)

What do you guys think...?

 

Remove torque management imo

 

Hahn stage V kit is the way to go or thats what i am planning on doing and its gunna be all sex.

-Stage V from Hahn
- HP tune (only at 15psi)
- Wot box
- 80lbers
- Hahn 3" catback
- dual aeroforce guages
- stage 2 axles

 

I did a lot of reading on this and yes it sounds great... faster and smoother shifts, but remember there is a reason that the car come with this... It is possible that missing on single shift can grenade your tranny! I don't really want to invest in a new one so that is why personally I think leaving it on is a better option. Just me though

 

Yea I see what your saying, I am basically stock, no egine mods cept cai and I hooked hp tuners up to remove torque management and manipulate the o2 sensor so I could pass emissions
