Guys,

If anybody has a similar setup to the following, could you please let me know dyno numbers, boost settings and afr's you are running. The more detailed the information you can give me the better. Dyno graphs would be REALLY helpful. I'm trying to get an idea about my current tune, and how happy/unhappy I am with it.

My setup:

Rebuilt stock Pineapple racing motor with 1500 miles of break-in
99 spec turbos setup stock sequentially with new check valves
PFC- Power FC
M2 carbon intake
ASP medium SMIC
Downpipe
Stock catted midpipe- cat less than 20K miles
PFS catback exhaust
850CC injectors X4 (primaries and secondaries)
Supra TT fuel pump
New NGK plug wires and plugs-BUR9EQP X4
Fluidyne radiator-and a bunch of other reliability mods

Tuned on 92 octane pump gas.

Thanks for the help,
Justin Wade

 

Here is my set up. How much boost are you running? I would say with your set up and 12 psi you will be hitting 380 @the wheels.

 

forgot to add sig.

 

You won't hit 380rwhp at 12psi if your life depended on it. The '99 are worth a couple more than previous years. Thats all. At 15psi, the norm is around 370rwhp. THats it. You want more than that, you'll need BNR's or a single turbo. The car has been around now for almost 14years. There's no secret sauce, just proven methods. I didn't see in your mod list that you had a Power fc, but if you don't, you will need it or something like a Pettit ecu upgrade. THe power fc is your best choice though. One more thing, get rid of your cat. Good luck.

Yeah, 380 is um well, not expected. I've been dyno tuned to 12psi on my Power FC (third item in my list). I'm looking to get some ideas of what others have made with similar setups. I know what I made, I'm just trying to figure out if I'm uhhhh, happy with it.....

So anybody else with 99 spec turbos and similar basic bolt ons let me know your numbers.

Thanks,
Justin Wade

 

Depending on your porting, you should be around 320-330rwhp at 12 PSI. As Ernie pointed out, the '99 Spec twins aren't going to give you anything more than the stock twins.

 

That's definitely not in SuperStock anymore

 

Yeh, 380 is kinda generous. ernie is right.

 

Bump up

 

Nope, its not I should change my signature and spend $20K more for making it ASP competitive

I have almost the same setup,except Street Ported motor, don't have a cat, and have a 3 inch mid pipe. I put 353hp down at 12lbs of boost with 91 pump. We ( Steve Kan and I) decided not to push it because the IDC was 89% at 12.5lbs of boost, the afr's were about 11.5 to 11.7 flat. I am happy I just wish my clutch was too! I will try to get the graph up soon.

 

+1 at 12 PSI, you're not far from the stock twins. Yours just spools a little bit faster! HAHA! I'll catch up!

 

o wow i think im going to be happy hearing all this lol i want to make 350rwhp on the stock turbos.. thats my goal and ppl saying with all these mods and about 12-15 psi of boost would get u to around that...

 

Can you tell me what kind of dyno this was on? And are you running 4 850 cc injectors.

These numbers are significantly higher than what I made for only having a midpipe.

Thanks for the great information,
Regards,
Justin Wade

 

Well, the midpipe could be good for 20 rwhp over a cat, keep that in mind.

Also, as stated above the 99 specs are really nothing more then fresh stock twins. You can search around for dyno results of stock twin cars with similar mods to yours in order to gain more data points

 

I've searched and came up with surprising little. Looked through every post with the word "spec" in it. Also looked through all 10+ pages of the dyno sticky. We really have less solid dyno data on the board than I expected. Hence my question.

the people saying that you can't make 380rwhp on '99 specs are wrong. Chris Ott at Rotary Performance makes 385rwhp on his tried and true.

 

Actually, you're wrong. I'm good friends with Chris, and he did indeed make 385 on the 99 specs----but not at 12 psi. If you go back and re-read the thread, it was stated that 380 at 12 psi wasn't possible with 99 specs, and it's not

 

i believe anything goodfella says

 

Here you go Justin, this is Wargasm's dyno page, which is great for comparing different FD setups. I had to dig around a bit but I found it for ya:

http://71.102.125.165/dyno.php

 

Lol!!! Nah, it's just a misunderstanding. The efini's can make that power level, just not at that low of a boost level. Hell, I made 352 at 12 psi with my BNRs with Chris tuning it, and he was surprised at that output......

 

That was on a dynojet, and ya I have 4 850s

 

u are smoking crack rock.

 

With stock ports you'll make 300-320 at 12 psi. Probably 345-350 at 15. Streetport 345@12 and 365-370@15. You might be able to make 380 at higher boost, or at 15 if they were non-sequential, but there's no way in hell they'll make 380 @ 12. Most mild single turbos don't make that.

 

That would be a waste of money since you cannot run in ASP either! Certainly not with the '99 twins. (or the Fluidyne radiator). You'll be in SM2 or BP.
