car should be ready to make some runs next weekend. i need to get some tires on it.
on a dynojet the car is around 300rwhp stock. from what i understand i will be around 400-425rwhp(dynojet). not a giant gain.
then add injectors and a little more boost. then add a cam, then fuel pump. then upgrade my 2.25" exhaust.... should be 600rwhp before long.

we had a little fun today. my hp tuners box took a crap so no tuning but we did make a couple of runs on the dyno just to see if it was safe to beat on the car.
stock should be in the 270-280rwhp range on a mustang dyno.
with a peek of 5psi it got 347hp/375tq
bumped it to 7psi and got to 375hp/400tq
both of those numbers were with very low timing. anywhere from 8deg down to 2deg so there should be a lot more power properly tuned. also the a/f ratio was low 11's and even into the high 10's so more power there too.
after we saw that it wasn't likely to blow up we went out on the street and ran it thru the gears. it seemed to like normal drive the best but was still shifting too high. power is falling off pretty hard up top. a combo of dropping boost up top and maybe the tiny exhaust? we were only at the 347hp setting when we went out for a spin.
seems like 400+rwhp should be easy with 7psi and tuning. i hope to get some mt's on there and get it tuned before next friday and then hit up the 1/8th.
car is VERY quiet. dyno tom said it was the quietest 375hp he has every heard

we were in a mad dash to get it running so we could go for a spin. that and i have no lift so taking pics under the car always look like ****. cant get a good angle.
i have to get the car back up in the air to address some clearance issues. i will get some more pics then. pics of the scavenge pump. stuff like that. we put that right in the front wheel well. there is a pretty large empty spot near the drivers feet.

went out for a gtech run. stock showed 13.49. at the 5psi/347hp setting i now see 12.80.
thats a decent start. now add a proper tune, boost and tires.
i have to say it feels slow as ****. needs at least another 200hp. with the tune and 7psi it should be over 400rwhp(mustang). maybe that will start feeling quick.
i am communicating with hp tuners to find out what is up with my box. they do respond pretty quick but i wish they had a phone number and live tech help. i might end up paying for another slot on someone elses cable just so i can get tuning on it. 2-8deg of timing has to be killing me.

woohoo. car is running strong. it actually puts you back in the seat now. front end comes up a **** ton and i am still at 5psi on the street.
after about 15 runs at c&s dynoshop tom got it dialed in pretty good. the thing seems to hate timing at peek tq. tom thinks it could be my restrictive exhaust or tiny cam. timing ended up around 11deg at peek tq and 15deg at the top. anymore and it would show knock. car was tuned with hptuners and a lc1.
5psi was 375rwhp.
7.2psi was 419rwhp :shock:
mustang dyno, 3rd gear pulls(forgot 4th gives better numbers on these 6speed autos), no lock up.
on that 7.2psi run the injectors were maxed and the a/f ratio was headed up. this was in an 80deg shop. no way i car run that boost level on the street without larger injectors. maybe 6psi but only if i am watching the scan tool and it isn't too cool out.
i think the ~7psi will be fine with some injectors.... damn, more money i might have to spend before drag week :bandhead:
. those numbers seem decent to me considering stock cam and stock 2.25" exhaust with 5 mufflers.
i have some dyno video but dont plan on messing with it till after we go to the track tomorrow.

Yeah I figured. But I've seen some people's mod lists and they are running 12.5's. Shouldn't be much more than 400hp cuz they are uncammed. I'm hoping the car surprises you the first time out. Get a cam in that thing and you should be putting down some serious power. I've seen cars with cam, header, and a tune run around 420hp. You should come out to KRP Saturday. I'd love to see that thing.

car didn't run so well tonight. best run was 8.26 at 87 with a 2.03 60' (12.8's?)
5psi, 91octane fuel from bp, 11.5deg of timing at peek tq, 15deg at 6000rpm. a/f ratio in the mid to lower 11's.
no matter what we tried we still got knock retard. ran the fuel from high 10's up to low 12's. definately got more knock retard while in the low 12's. thought it might be heat soak from sitting in the staging lanes so we let it cool off a little and that didn't help.
last thing we did was put the timing to a flat 10deg up top and make a run. no knock. at least we are learning something. it appears to be real knock that the sensors are seeing.
question is... should we be able to run 5psi with 11.5-15deg of timing on 91 octane?
thinking a meth kit should be next, then a converter.
