this one guy i work with has a 1st gen tsi

he 'said' he has a t-20 turbo, shotries headers, 280 cam, intake....turbo is pushing 22lbs?

he said with that he runs mid 12's......in 1 month he BLEW his pistons 3times and a head gasket once....he wont believe me when i said hes pushing to much boost....

long story short.

after i get my 373, lt headers, tsp cat back, and lid.

if i race him from a roll will i win?

you might want to start with the obvious and state what you are driving?

I say with a tune and those mods you would be running door to door with him if he is running mid 12's.

Never heard of a T-20 turbo.

Could be a T-25 from a 2G, but that doesn't make any sense. Maybe a 20G?

How did he have time to replace his pistons three times plus his headgasket in one month?

Is the car a hack job? Is it tuned?

Someone isn't fully clear on the mods, either you or him.

i didn't even read your post but i can say "NO" for sure since you can't even figure out where to post your thread you won't even find the street you're supposed to race whatever it is you were supposed to.

Does your keyboard not have a shift key OP?

Also... T-20?

If it's a T25 then it is way out of its efficiency range and should have blown up before his pistons or head gasket.
That is, unless it's a T25 from an SR20.

EDIT: Apparently a T20 is just a smaller T25, as I suspected.
It's essentially a tiny turbo used in some entry level honda builds.
If he has that than I don't think you have anything to worry about...

a 6bolt 4g63 that come in all 1st gen DSM's can handle 22lbs on a good tune.. As far a t-20 turbo, i've never heard of it.

AWD_Launch

Blew pistons 3 times don't have any idea how you can do that to a 1st gen unless you have crazy amounts of knock which would be from a very bad tune. 22PSI too much I run 25PSI on a bigger turbo with a stock 190K bottom end and still hold great compression. It is all in the tune.

1992TsiAWD

22psi can certainly be too much if you don't have the proper fuel and tuning modifications done.

Subscribing!

So he has two headers and one cam? Are you sure he doesn't have an LS1?

I was trying not to be a dick for once in one of these threads. I noticed that as well.

As already stated this is in the wrong section and should be in bench racing section (sub category in the racing lounge). I say lol. Jk. If you are driving an ls1 fbody with those mods I think you will take him, if you know how to drive. Should be very close if all your information is accurate imo.

You might want to omit that double negative statement before critiquing other's posts lol.

ytownls1

its going to be in my 1999 z28 a4

and sorry about posting in wrong section was in a bit of a rush.
yes all the mods i said are what he told me exactly.

All i know is he wants to race me for 500 and he tried to race me already on a city street during rush hour and bragged how he smoked me because he was weaving in and out of traffic..

I just want these mods done and see if i can make a easy 500bucks

iTrader: (2)

I wouldn't do it for 500 ,not with your mods,I would stay clear of that bet! Your pretty much stock.what kind of tires are you running?If your gonna race I would stick to a dig,that's my opinion he could be blowin smoke up your *** to get ya to run,I see him picking the race,and winning.

BOBS99SS

iTrader: (2)

if your looking to race for money and have to ask ( will I win) I would stay away from putting that much up.have you been to the track in your car? I assume no,just know when some guys say mid 12s and money is in the pot that could very well mean mid (LOW) 12s lol,

ytownls1

i havent beem to a track yet. but i raced a 1995 z28 with light mods have couple videos posted on here not of our dig race yet.

any way when i raced the 95 z28 from a dig i was about half a car in front of him... we backed off at 115 so we def ran a qt mile. last time he was at track he ran 13.5, and still cant beat me.

'If' i race that tsi i really dont want to do a dig because he will smoke me def off line and maybe more. I wanna learn more about the engine in thoes cars and find there dead spot

1992TsiAWD

Their dead spot is a low, low roll, as in 5mph.

Their specialty (if AWD) is off the line, obviously.

From a roll, a lot depends on NLTS or antilag, especially with laggier turbos.

If he actually has a T-20 turbo, there's no way he's running 12s. I doubt that's what he has, especially with 280 cams. He's mistaken (or you misheard him).

264 cams are a mild upgrade, for stock framed turbos (up to ~450hp generally).
Good for 3500-7500rpm or so.

272 cams are for medium sized turbos (up to ~600hp).
Good for 4000-8000rpm.

280 cams are for large turbos (600+hp).
Good for 5000-9000rpm.

288 cams are the most aggressive commonly used cams on DSMs.
Those are for all-out race cars- 7000-10,000+rpm.

The bigger/more efficient the turbo, the higher you are going to need to rev, to make use of its efficiency range.

It's entirely possible that he has way too big of cams for his car, and are taking away all of his mid-range. You need a pretty damn big turbo and a fully built head to rev high enough to make use of the 280 cams' powerband.

yes hes awd so a dig race is def out

thanks for the info ^. ill try to talk to him more and see if i missed/miss heard anything.
