Just felt like sharing my recent dyno chart with you guys, im not new to the site but this is a new screenname for me (was tthame1, long story why its changed) anyways i made these numbers on 18psi this past weekend. The conditions were pretty crappy to dyno in but what the hell. I did find out what makes my car beat alot of 400whp hondas when im making 360whp, the power curve is the best i could ask for. This turbo works great on my setup.

setup:
81.5mm b16
(stocksleeves)
je 9:1
eagle rods
sk2 valvetrain
pnp head
inline pro mani and dp
SC6152E
hondata s200 tuned by street driven performance
af ratio was 11:6-11:7 at full boost



dynoed previously on 12psi 322whp 220wtq but that was in 70 degree weather.

I guess 360whp isnt good enough anymore Im gonna get a bigger intercooler, im just running the one off a drag kit right now, maybe some bigger charge pipes too.

Here are some pics of the car for those who havent seen it

When do you notice your full psi? and when do you start to spool up?

Im just making a comparison and thinking about differences of when my sc-34 will spool on my b18c.

Anyways, good numbers! How are the traction issues with street tires?

Are graphs look kind of similar but I made 334hp 246tq at 16-17psi on pump gas with a SC50

I don't want to jack your thread, so if you want me to post up my dyno to compare let me know.

inlinepro 3in downpipe?

just wondering, i made 383/270 on my GT35e at 13-14psi. 480whp @ 19psi. i know the gt35e has a different turbine, but the same compressor housing, could have been the extra displacement i have, but interesting. Either way, good numbers for you, i know anything above 300whp on a street honda is a blast to drive.

Well it hits 10psi by 4k rpms and it hits full boost right at 5800 (notice the jump in power lol) Traction is non existent until about 70mph.

11psiturbosi, i would like to see your graph to compare, post it up.

Seen4ever- It is only a 2.5 inch dp. that reminds me what do you guys think i should do, get a 3inch dp and run it through my current 3inch exhaust. Or should i just pu a cutout on my current dp?

As far as the power goes, the weather was mostly to blame, i previously made 322whp on 12psi in 78degree weather with 20%humidity. This time i only made 298whp on 12psi so it about 20whp off because of the heat. Im pretty cetain that in the same weather i dynoed in before it would make 380+whp on 18psi.

Im not complaining though, i run consisten mid to high 11's with this setup at only 117mph, i wouldnt mind a highger trap but it just proves that i have a good setup the way it runs now. Most people need 400+whp to run 11's and need 120-125mph trap speeds as well.

Wow that sc50 spools real fast. Youre making about 50more whp until 6000rpm the the sc61 power on mine comes in and climbs up from there. Thats a good comparison.

Whats your motor setup?

Damn Nice Setup and Great #'s

3in downpipe would kick up your numbers a good amount. me personally i would just get 3in downpipe to go to 3in exhaust, this is exactly what i have on my car. I wouldn't go though the trouble of a cutout, as there are alot that just fall apart.

oscarmayer

same graph i get with me built D motor. I am begaining not to liek how if you lef toff the accelerator when when shifting anymore than 1/4-1/8 you end up with a dead spot due to turbo lag and it trying to catch back up. I'm working on trying to find a solution to this, maybe some sort of backupore sytstem liek they use in ralley racing that can pop off when i let off the accelerator mor ehtan 1/4 throttle and i'm in heavy boosting to help keep the turbo spooled. Who knows, it's ok for a drag car, but for a street car, i'm begaining to think twice as I like all around performance not just drag.

We had some electronic issues that kept us from going over 7500 rpm before it firecrackered and poped. you can see the slight dips at the top of the band. and we let off so there was still more to go. It's an 11k rpm motor and my redline should be 9800. We'll get it fixed and repost better numbers. this was 24 lbs on race fuel and only half way through the actual powerband.

*sorry for crappy pic. my scanner is broken (thanks kids) and all i had was my digi phone cam.**

mmm, turbo lag. what housing size do you have?

0BoostedJeff

Here is mine, b16a, 81.5mm, sc61e, 22psi

oscarmayer

SC61 not sure the housing, it's a precision built turbo. I went to the track and i can;t get traction. it comes in at 5500 and by 65 it's nearly full boost and spiinning tires in 4 gears. (street stuff). not sure how I feel right now, cause i was hoping for better overall traction. also with not being able to rev into my top power band it's also a damper cause it's limiting my overall control of the car.

I'm considering goign to a smaller unit as even though i had thougth of 500 hp it's not going to perform thw way I want it due to how it runs on my car. well at least this unit isn't I want a turbo that will boost well at about 3500 rpm and hit full about 5000-6k and hold till red. I was thinking of maybe a gt28 or something, but not sure again, i'd consider lower power for better over all smoothness in the mid range area.

Good numbers man, why not pull it to higher rpms? Im pretty confident that when fall gets here and we see some good 70degree weather that on 20 psi it will make 400whp, i cant really go any higher with the intercooler i have right now. Its all good because i dont need to be going 11.49 or faster until i can afford a roll bar and scattershield.

18psi? wow, it seems to be really low on power. i'm runnin 10 psi and sittin at 299 hp on a bonestock block

Its the weather man, the car was down 30whp from the last time i dynoed (back in april 322whp @12psi, this time 298whp @12psi). There are so many factors that come into play you have to think about. This car runs like a 400whp car, in fact it has beaten several. With the times this car has ran (wich is always at night somehow when its 20 degrees cooler) it should make no less than 380whp.

Heres the video Henry was talking about, this was on 10-15psi (300-330whp).

SAE correction takes a lot of the gains/losses associated with high ambient temperatures out of the picture. It's supposed to correct all dyno runs to 70 degrees ambient.

dang, nice numbers guys....

sc50 turbo is the shizzinizz son!

i can't spin it any higher because I am only running Itr valve train. when money comes, i will build the head, until then, 8500 is enough for me
