what should happen if you change your e85 for pure methanol in a 16g drag setup?
will the exhaust housing will stagnate for being small? methanol needs more than 50% more fuel compared with e85 ..
Pretty killer power on the "heart break dyno"
When you installed the kelfords did you install them straight up? I was thinking a decrease in overlap would help with all the back pressure.
Little update on my car. I added 2 nice mods to my car. Removed the FP2 cams and installed a set of Kelford 272's. Removed the EVO3/RVR intake manifold and installed the new version of FFtec Motorsports SMIM. I had it on the dyno last Saturday, then hit the track last Sunday.
I'm very happy with the new SMIM from Full Function. It's made for the 2G head, uses large round runners where it meets the plenum, large volume plenum, and the runners have a continuous taper from the plenum to the head. The throttle body plate is offset to the top of the plenum so the UICP fits with a slight adjustment. I didn't need to fab a new UICP, all I did was loosen the couplers and readjust the angles a little and it fit easily. The reason I'm so happy with it is because it made some nice gains in top end power on the dyno. I started the dyno pulls at 4500rpm since my wastegate tends to spike boost over 38psi at low rpm on the dyno, and it scares me a little. So the dyno chart compares the best pulls I did last January and the best pull I did with the new cams and smim. 438 AWHP on a Mustang dyno, 15hp peak gains, 18hp gains at 7k rpm, 26hp gain at 7500rpm. I really like how the power stays up at high rpm despite boost dropping off.
Awesome job man!
438AWHP on a mustang dyno is just ridiculous! Curt Brown's 499AWHP record was on a dynojet, right?
I had a few questions for you, but understand if they cannot be answered.
What kind of gas did you use when you hit the dyno, and the track? What does the boost look like when your making that dyno run at after 4500rpm? What boost are you running at the track? By the way, I was wondering if this is on the valve spring wastegate actuator that you made, and down-flow outlet? What is the weight of the car?
It is just crazy that your horsepower stays so flat and the torque curve barely drops. Your still making 420 horsepower and 270ft-lb of torque at 8,250RPM! This is, by far, the best 16g dyno chart I have seen so far.
At this level, would a turbine wheel clip helps things out? It is old technology, and reduces response, but it could help with keep the torque up.
Keep us updated! Great Work!
I'm logging with a Palm m515, so there's no elg file to share. sorry
I'm glad to share info, just ask!
I'm using E85 all the time. I think I filled this tank at the Chevron station in Fremont. That's the place right next to the Fremont Police Station!
Boost falls like a rock after 5500rpm on the dyno where it peaks at 37psi. The logs show 29psi at 6500rpm and 23psi at 7500rpm. I'm still using the downflow outlet and valvespring wastegate mod, so I'm running as much boost as it'll hold. Oddly, boost stays nearly level from 7500rpm and up, it doesn't fall off hardly at all at high rpm.
I tried to weigh the car when I was at the track, but the scale was broken. I estimate it weighs approx 2800 with me in it. I haven't taken out much weight since I claimed the 14b record 2 years ago so it should be close.
Yeah, like I said I'm very happy with the gains in top end power! The big cams and new SMIM were the key to the new gains. I can't wait to take it out and really push it! Think about it this way; I made around 430 AWHP on a Mustang dyno at 23psi (at 7500 rpm on the dyno chart) on a 16g that I bought used for $200.
I forgot about the option of clipping the turbine wheel. I'm not sure if it helps or not at this level. I have to think about it.
Thanks, I will definitely take you up on that offer and ask as many questions as I can think of.
37psi makes for a nice torque hit I bet! I am surprised as well that you were able to hold 23psi to redline with the mods your running. That is definitely not what I expected. How many miles have you put on the 16g sense you started running it this hard, and where do you feed it oil from?
By the way, what kind of timing are you running? What kind of ideas are you throwing around to push this setup even more?
It is hard to smog around here, is this a street car? And, what track do you usually go to?
I always get carried away with this question asking thing...
Quick update; I went to the track last Sunday and got 2 runs. The first run was a test to see how the tune looked. I ran 10.9 @124mph with a 1.53 60' time. I missed 4th.
The second run started great, another 1.53 60' time, the 330' time was .06 quicker, but as soon as I hit 3rd gear the car sputtered and misfired. It did the same thing last time out and the logs show the same odd trend. The AF ratio gets a little richer than normal and the boost goes up a few psi higher than normal. I'm not sure where the extra boost is coming from since my wastegate is just about welded shut anyway. I have to try a few things and see what happens.
Ah must feel nice to miss a shift and still hit 10s! What did you end up doing with your WG? Last time a read it still had a valve spring on it?
Haha, yeah I know...
I had a bad run and only hit 10.9!
I'm still using the same 200 pound wastegate spring. I changed the NLTS code to spool the turbo quicker between shifts and it seems to work too good. I'm pretty sure I'm getting compressor surge just after the 2>3 shift. I'm not 100% sure how to fix it since there's no SP cover for the 16G. A friend offered a suggestion a couple months ago but I didn't hear him until now.
when u were o the dyno did you ever witness the wg opening
at all w your setup?
also...have u seen this?

if you rotate the air the same direction as the comp it has been proven to eliminate surge in some cases... just a thought.
