I just spent quite a bit of time going over the 1/4 stats on the board.And what mostly strikes me is the relatively slow times with various combos compared to the board hype about how fast certain turbos are or can be.

I keep hearing how the evo 16 can run 12s thought someone even said 11s but don't think found even one instance of an 11 sec evo big 16.

Heck even the greens and other 50 trims don't seem to be in the 11s very much and not usually low 11s. And while 12 second cars aren't slow by any means I guess I was just expecting a bit more.

Now I realize there are probably lots of people maybe who have run better times but this board at least has timesplip documentation to verify the runs. It appears that low 11 second ,or 10 second talons are certainly not very common and need huge mods to get in that range.

Again not complaining so much as just trying to get some realistic expectations with what kind of times my car might be able to get with either a evo 16 ,good fmic and good fuel and injectors and tuning versus going up above that to maybe an agp 50trim again with full supporting mods. I was hoping an evo could put me mid 12s and a agp rs49 could put me very low 12s or in the 11s.Am I just dreaming here guys???

And if some of you guys with the two above turbos have run great times mabye you could email me or post your mods and times even if they are unverified I will just go on your word,good enough for me.And please no corrected for altitude times or any of that stuff unless you want to tell me the altitude of your track.Not sure how much factors like temp,humidity and bar and altitude affect turbo cars.I can see temp and bar affecting things maybe but thought altitude had no effect since turbo cars make same amount of boost at any altitude.

As wonderfuel as this board is, www.dsmtimes.org is your friend when it comes to looking at fast dsm times and knowing what turbo was used.

You also need to remember that a lot of people aren't the greatest at tuning their car's combination...and that means A LOT. That along with not having all of the supporting mods for the turbo on some cars. Race gas makes a huge difference too.

Some people are also better drivers than others. And some people are more willing to abuse their cars for the faster time slip. Faster shifts, WOT shifts, things like that add up. There are lots of reasons why the bigger turbos may not be posting as fast a time. One thing I noticed is that with a 50 trim, it takes longer to respool between shifts, so that costs a little time down the 1/4 compared to a smaller turbo that spools quicker.

Spool should not be a factor in a race situation (i.e. RPMs always >5K).. if you are moseying along in traffic then yes.. lag will be there

Also to chime in my .02 on turbos in general... HP ratings on turbos are usually estimated by compressor air flow in lbs/min x 10. What this means is that in perfect tune your car could make +/- that number. This does not mean strapping X turbo on will give you Y HP.

Also note that the DSMTimes.org doesn't show car weight.. which is a huge factor into some of the fastest "small" turbo times

Good observations. PM sent.

. Currenlty #30 of the fastest 1/4 times.

Unless you are WOT shifting(which quite a few people do), then there will be a time to respool between shifts, even at >5K. I can see it on my datalogs, and can compare it to other peoples. I shift at close to 8K, so I know its not a problem of me not keeping the RPM up. Smaller turbos respool between shifts quicker. The difference in spool time can be a few tenths of a second.

There is no reason why an evo 16g can't beat out a big 16g by a hair in ET... In fact all things being equal between to cars except one with a B16g and one with a EVO 16g the evo 16g should come out ahead.

Give the list time... As more people run them and get good at it they will show up right with the b16g fastest times..

Again not complaining so much as just trying to get some realistic expectations with what kind of times my car might be able to get with either a evo 16 ,good fmic and good fuel and injectors and tuning versus going up above that to maybe an agp 50trim again with full supporting mods.

You could do it with a EVO 16g but you will need everything you would need with another turbo... Weight reduction..(moderate.. jack.. spare.. light wheels.. etc) a FMIC. Depending on how you are planning on controling them I'd go with the biggest injectors you will ever need... like even if you later sell the 16g and go bigger you are covered. That way you can max out on pump gas too..

IMHO.. Spend a bit extra over that EVO 16g and get a hybrid.. I'd start at a 50 trim..

Also, on this site the 1/4 mile times could be old... I know many people have run times w/ their t25, and since gotten bigger turbos and different setups, but never got an updated time at the track... so it appears that a 50-trim ran what a t25 actually ran.

The toonerz on here aren't exactly the best resource to find out how fast a turbo will go. Check out NABR if you want to see some good examples of a turbos' capabilities.

We aren't racing turbochargers but cars..

As for some "tooners"

Some have ran 12.5 on a just 14b.. some other people... ahem... on here have done cams, Full T3/T4 tube mani, ext gate.. big turbo etc... etc and are only .6 to .7 seconds faster in the 1/4 despite all that extra...
