After talking with my shop [ car woiuld have been ready to start today ] we have decided....well I did . To put the smallest pulley [ 2.87 ] on and install a waistgate and manual boost controler and bleed boost off at 10psi to start with . I will get to 10psi sooner and the motor will not have to work as hard to push the extra boost thru the IC . Belt slip should go away totally because preasure will never build past 10psi between the blower and IC . We are hoping the boost doesnt drop off to much as I have seen with the one other person that has tried it . He tried it with the stock SC-trim blower . With the T-trim , boost is building the fastest just as it reaches 10psi . I was spinning the blower at about max rpm recomended by Vortech with the 3.12 and the custom 34 tooth cog pulley . So I will be over reving it , but not putting so much stress on the motor nor the blower.

With all the heads lifting , moving . What ever is going on . I want to keep my motor in the car for a summer or two . I havent driven this thing much at all in the last two .

Along with the waistgate , water/meth injection , and most importantly...Me not tuning the car [ shop is doing it this time ] I hope to have a fast and safe car for the summer and maybe during this winter I'll go with a EMU that can control things better

 

good luck with everything,i hope now youll be able to drive the car without worrying whats next.it would drive me nuts not to be able to drive mine.

 

sounds good.

I'd love to see a T-trim dyno to compare it to a SC-trim with different pulleys

 

I have mine here . I'll see if I can scan it and post . I dont think it has A/F and boost levels though

 

Here yopu go . this was the power curve run . It made about 10 peak whp less because A/F drops with more load on the motor

 

booger, have you measured the pressure differntial before and after the intercooler?

you shouldn't be coming anywhere close to maxing out a t-trim. if so, you'd be putting up 700rwhp numbers.

I have a feeling that the intercooler and piping are a big restriction.

 

Well I had the 3.12 pulley on with a 34 tooth cog pulley on . I dont think its maxing out the blower , but spinning it to there max recomended speed . The belt slipping is whats killing the boost from building further . I beleive if it wasnt slipping . I would be upwards of 16psi to 18psi at 6800rpm's

We gave up on the wastegate idea . Just wasnt working right . Shop is pretty sure that the W/M injection , HKS gaskets , And the L19 head studs , it with hold the boost . We had a set back when we went to tune the other day . I ended up with a misfire that we couldnt find the problem . I found it yesterday , it was the injector wire plug . It wasnt pushed all the way down , so it wasnt getting a good signal or no signal at all . We will finish tuning at the end of this week when its cooler out .

 

i just read up on some of your old threads. I realize now that you have already gone w/ a bigger IC and 3" piping!

are you still using the SS box? what have you done for the reast of your fuel requirements?

Sorry for all the questions. I am making my decisions on what parts to order for a vortech setup on my sedan.

 

Full fuel upgrades , return , 550's
Still using the SS box . I still dont feel the need to jump into more problems right now . Its working great .... the Utec is buggy...the AEM is looking better and the shop knows alot about it

 

how did you get the ECU to adapt to the 550cc injectors? reflash?

 

Good luck with your plans booger, sorry but I jumped ship....

 

Yes...flashed for the 550's only

 

Can't wait to see the final outcome!

 

I got thge final tune done today . With out any timing being put back in than before . I only made 425whp and 338trq. Again this is on a Mustang dyno . We did add 2 degree's back in and made 430whp . But the com port on my computer took a chit and we couldnt datalog the knock volts so I said we arent going to go any further and I put the timing back . The tuner wanted to put back 2 more degree's because he said it did make more power adding thw first 2 degree's in . But with out the logger I absolutely do not want to take any chances .
All we did , besides the W/M injection . Was to lean it out a little in the mid range to a high 11 to 1 and kept it rich [ low 11 ] up top . Im happy with what it has now . Maybe next summer I'll retune it again and get some more out of it....The tuner said there is more there , but with out the logger Im not going to try .
