what do you mean? no one is pounding me, just a misunderstanding

oh, did you mean the discusion? you know where people debate and talk about things? yeah that's what that thread is

 

+1 8 psi dyno plot coming next week Then 15psi after tranny upgrades Next summer is going to be fun. My car spent too much time at the shop this spring/summer. I'm definitely looking forward to next year

 

That will be awesome. Please do post a ~8psi dyno. I would like to see how it looks at that boost level on a built motor.

 

I'll give the nod to the TT setup from a dig, but from a roll, especially with a 6mt, I'll give the nod to the Vortech. This considers similar hp and torque numbers between the two. The vortech does much better with the manual tranny, because the driver can dictate what rpm he starts the roll-on race.

 

You really believe this? Same HP? SC and Turbo will never have the same HP/TQ #'s and don't you think Turbo with also 6MT can dictate what RPM to use? At 3500RPM a Turbo will already hit Full Boost and your Vortech wouldn't even hit half that boost Please look at the power curve of both and you'll see that Turbo will have more power under the curve


Please look at this thread.

Edit:

Granted from a roll there is a delay maybe .5 Sec for Turbo but within 0-800RPM the turbo will go from vacuum to full boost while your Vortech won't hit Full boost until Redline. Plus you can Brake Boost from a roll and once you let go of the brakes Turbo will already in FULL BOOST at any RPM

 

While this got sidetracked a little (nothing a little math can't solve), the original post was well-written and very informative. Nice job 617G!

Which tranny build did you choose (I assume you went with SGP or GTM)?

 

Thanks. I've actually decided on a Edge racing TQ converter and a SGP VB first. If that doesn't hold up, then I will build. I think 450whp is the sweet spot for the street and once those components are upgraded I should be okay, but we'll see.

 

Good choice

To the guy who posted that the Vortech would win from a roll if both had the same HP/Trq.....I have never seen a Vortech that can put out as much Trq as a TT even if both had the same HP, it just does not happen.

My Vortech had 440hp and 330Trq and my TT has 410/400, there is just no comparision even from a roll.

 

I take it you have timeslips then to prove it? jk

everyone with a turbo "feels" that their car is faster
they "feel" faster than modded NA vettes

I drove a stock STI once and it "felt" about almost fast as my car right when the turbo would kicked in, but I sure as hell know it's not actually faster than my car

IMO, if you were making 440whp with the vortech, but only 330 tq, then that probably isn't faster than a 410/400 APS TT car. It might be sorta close, but I'd give the edge to the APS setup in that race

what if your 410/400 APS car went up against a 475/440 tq vortech? That's the same % increase in power that 617G's vortech had over his 4psi greddy

 

Sentry I do not want to start debating with you on which is better as you already have people who will do that for me but when I had my Vortech (41,000 miles with it) I ran a modded STI and I did beat it but not by much, this is when I decided I wanted to make the move to the TT setup. I got it back and ran the same car and guess what I beat it by 8 car lengths and this was from a 55 roll.

Do not need timeslips when you have the same car to compare to.

 

obviously you went into a faster setup which I said in my previous post

I'd assume the APS with those numbers would be faster than your old vortech setup

 

You added a smiley whilst I was typing so I will be nice to you also

Missed you last comment about the race with your setup, unfortunately a man called Sam has my car and it will no longer be 410/400, we decided to drop compression and produce more power so I have no idea what it will be until next week when I get it back.

 

Actually, I do believe this...I posted it. You're assuming that I'll start a roll-on race from low rpm. With a manual and rpm-based boost, I can start the race at 5k if I wanted. I'm aware turbos make more torque down low and I know how to read a dyno. I made my post based on the original poster's assessment of a 4 psi TT setup vs a 9 psi Vortech. I mean, that is the topic of discussion. I was just agreeing with the OP. Do I need to repost his reply? Did you accidently make a post to the wrong thread?

 

look forward to the results man

yeah, text is a bitch. People end up sounding harsher than they normally do. I don't always catch myself

 

Yeah it does but no hard feelings. Also the Blackberry never lies so I also saw the post you made before you changed it and posted this one... I love these gadgets...lol
