[Hmong_1G]

So today I got my car dyno in. List of mods and more.....

Rebuilt .040 probe pistons w/ 2500 miles full balanced
HKS downpipe
No cat
RSR full catback
bcpr7eix spark plugs
lexus is300 coils
stock ct26 with 170,xxx miles
cometic 1.4mm
blitz sus intake
Walbro 255lph w/ rewire
10lbs psi
custom spearco IC with 2.5 piping w/ hks bov nonrecirc
All EGR and emissions working and installed
Stock ECU with no piggyback.
Everything else is STOCK.


This is all I can think of that might reflect of the numbers and scale
Dyno was done without a Air/fuel readings.

WHP 275.13
TRQ 285.32

SO I'm happy with the results but my brother isn't as the hp and trq lines are flat. Anyone with experience please shine on in with your thoughts.

SORRY not the best picture as its from my phone.

Not bad at all man!

 

[CajunKenny]

It's flat because of the stock ct.

Those are great numbers. I'd be happy with that too. Good job!

Really? You think so? This is my first Dyno.... and my brother says the curves are very flat and it falls off at the last 1-2k rpms. I actually think its good numbers on stock turbo and ecu.

Thats what I said too. Considering the age and its maximum efficiency at 10lbs I couldn't be any more happier.

A ct26 can do more than 10 psi with no problem.....I see 300hp being easily obtained!

Boost always falls off at high rpms on a ct as our motors can breath more air than a ct can push....I'd shoot for 12 psi on that ct and see what happens....14-15 seems to be where the ct runs out of steam in stock form.

Yea I tried... but I don't want to run a MBC especially a bleeder type. I have installed the maxed washers possible and was only able to obtain 10lbs psi. Its ok as I know more is possible but taking into count the age and the two fins being damaged... The power output seems reasonable. Thanks gaboon and kenny on ur responses. I will be going with a ct26/57 (my stock one is burning oil)and a maft pro soon. After that I think I'ma call quits on the upgrades.

 

[CajunKenny]

Also, remember that our engines have a flat spot at around 5k.

Yeah, like gaboon said, you can get a bit more power out of a stocker with more boost.

Just make sure you've got all the supporting mods and a 57 trim will treat you nice. That 57 is a real tire burner! :biglaugh:

If you want to run more boost you'll need to get the lex AFM or go maft. With the lex afm and a safc you should be able to run more boost and get a little bit of a tune which should get you to 300 no problem.

You can squeeze 300rwhp out of a stock ct26, but that doesn't mean it's a good idea. Back when I only had the following:

Lex AFM
RC 550cc injectors
Fidanza LWFW/Stg. 3 clutch
BIC DDP, running open downpipe
Stock CT26@15 psi, falling off to 13ish near redline

I made 289rwhp/295rwtq on a Mustang dyno. Everything else on the car was stock. Considering that you have an upgraded IC, you could push that CT a little more. Just keep in mind that the harder you push it, the hotter the air charge gets which will bring you closer to that detonation threshold.

 

[rtrdpenguin]

Great numbers I have nearly the exact same mods and made 270/260 at 10 psi

Do you have any issues with boost creeping to fuel cut? My car does that and I can't seem to get rid of it no matter what I do....

Boy do I miss my 57 trim...

I have no issues with boost creep. I forgot to mention i have the LIPP elbow and that psx thermo shield ( I think BS). I did have issues with spark blowout until I went with the colder plugs. Seems my compression is a bit on the higher side. I know my exhaust system can be worked on a bit as It is choking a bit.

good #s...were did you get it dynoed at..?

Yea that does seem a bit low. I just can't seem to get the darn ct26 past 10psi. I know for sure mine is leaking oil a bit once it gets to op temps. I like the numbers my 7m is putting out and soon the maft-pro and ct26 will be next. Gonna break my friends 380 whp and 410 rtrq 7m numbers. I know those numbers are possible with only 4 more parts.
1. ct26/57
2.maft-pro
3. 550cc
4. FPR

My buddies at UTI. 3 pulls with consistent numbers.
