I made an attempt at tuning my car last year, installed some Kelford 272s and without changing much and lowering the boost I gained 10 HP. It was hard to find more hidden power in timing so I think I've gone aa far as I can, Buschur will be my next stop. In the mean time how do the curves look on this graph. Nothing impressive, but I thought they looked pretty smooth and the power stays there while the torque tapers off. It could really be garbage, I don't know, just looking for some opinions.

 

whats your mod list? on stock turbo?

 

No, power seems low for my mods. Evo 9 10.5/20G turbo at 25 psi, Megan tubular manifold, open wastegate dump, 3 inch turbo back, no cat, Kelford 272s just installed with the spring kit, injen intake and intercooler piping kit, 3" core intercooler, water/meth kit,Denso 720cc injectors at 90% max DC. I'm sure there's more in it but I'm an amateur tuner at best

 

im not a tuner myself but it is low for DJ. but if that is what you make on buschurs dyno, it might be close. if there are no other tips from here, im sure dave can sort it out for ya! i know wiht my mods i put down 342/320 Dj on 93 with 9.8 turbo.

 

that's pretty danged low. hard to say if it's the tune or VD settings, though. and it's really strange that your power curve just goes completely flat.

i made 333whp on a stock IX with a FMIC, injectors, and 3"TBE.

 

Those are the mustang Dyno numbers. Dynojet numbers were 353 and 347 or so IIRC. I know Dave Dyno is a heartbreaker so id rather see the low side of the numbers. But I agree, every one says my numbers should be higher, and it probably has something to do with my tuning. I'm not going to bull**** anyone and say that's as good as it gets. I'm sure Dave could get some hidden horsies out of it.

 

If it was me, I'd assume your still on pump? I'd look at a few more mods before I'd take it to the experts, like increasing the size of the injectors and a walbro. Or I'd look at running e85 and doing the injectors and pump too and maybe a cop kit.

 

Forgot to mention it has a Wally 255, I would like some 1000cc injectors but the 720s I got are at least better than the stockers that were at 110% Duty cycle. And I don't have anywhere within 50 miles of me that sells E85, it would be easier to run VP110

 

Your injectors are good for a very safe 360whp on 91. That that's fine for the stock turbo. You just need a proper tune.
No reason for more parts. Unless you're just not done building the car how you want, of course.

 

for 25 psi with that set up Ide say your right on par with the power you should be at with your mods. First off you need to get rid of that injen piping and convert to speed density. Also I have a feeling you are not optimizing your tune with your water meth combo if you are a "beginner". So dave will get more power out of it def.

 

How do you figure all those mods only equate to 312whp? I missed the part about meth injection. He should be killing it with the dyno numbers.
And why should he go with SD, especially at this power level?

 

He said on a dynojet setting he was at 353whp, and hes running injen piping which is a bottle neck, and going speed density will pick up about 10whp over that maf, from the cars Ive tuned. May just be due to the design of the intakes and no restrictions but they tend to pick up power. But mainly I believe he hasnt optimized the tune for meth injection. With better piping, speed density and a retune I would imagine that car would be around 380whp on a dynojet, maybe more but I wouldnt really push a stock turbo past that (My opinion)

 

I dunno what's going on with my phone, but I never saw the dynojet numbers, either LOL.
350 sounds a lot better. Man, what a difference between that and a Mustang dyno. I wish everyone would use a common dyno. Anyway...
I agree he should be a bit North of 375, with the meth.

 

Appreciate all the replies fellas

The only future upgrades Im planning are an FP black turbo setup, only because Im getting EVERYTHING to bolt it on dirty cheap. Run that until the stock motor gives up and then drop in a built Buschur block.
I hear a lot of bad about the Injen intake. I think its better than stock but I think this summer I will upgrade to a better piping and intake kit.
The water/meth injection is really just a knock preventative measure for me. I was getting 1-2 counts of random knock in my pulls even with low timing numbers, so I use 1 gallon of distilled water and one bottle of HEET to get about a 10% mix of water/meth. I immediately noticed my knock go away and was even able to get up to 6 degrees peak timing at 4500/full boost with no knock. I cut it back down to 2-3 degrees just to save my engine some abuse. But yes, Im sure if I get tuned on 93 and with a proper mix of water/meth I could make more power

 

as long as you actually do those upgrades, you should be good. i only say that because so many people go with "bigger and better" parts that aren't the best now, but will be "later".. but "later" never comes and they are disappointed with the car.
i've been slowly upgrading turbos over time. i prefer to have what works best for my car now. the black is a bit laggy, IMO, unless you are going with a 2.3 or 2.4. unless, of course, you are going for peak WHP numbers and aren't worried about what they car does below 5k RPM or so. it's all preference, really. i have a friend that doesn't like when our cars "make too much power too soon". i think that's odd, but to each their own LOL
as for the Injen stuff: i had stock.. then Injen because i got it really cheap... then back to stock. to be honest, i notice no difference other than less "whoosh" from the turbo.
