Duh, thanks. Refresh my memory, and I cut 25% of req fuel and multiply VE cells my 1.25 and the adjustment will balance, right?

Dyno guy never called me back, I'm a little disappointed. The road tune is much better but the car is still slow and it's begging for some real tuning. Time to watch Californication with the cats.

Californication?


Slow relevant to your turbo car, Hustler, or just slow period? I.e. a minivan would embarass you?

Close. You actually multiply your VE table by (old_req_fuel / new_req_fuel). So using your example, if you reduce required fuel from 10 to 7.5, you would multiply your VE by (10 / 7.5), which is 1.33.

Not the end of the world if you have to road tune it. You just won't have that number to talk about here until after Hallett.

If it still has the 3.63 gears, that'll really hurt it. Hoping you can arrange that 4.10 for MHX.

So, this is a road tune with pretty-good AFRs and not detonation. I was getting the sounds of weird flame propogation through the det-cans (buzzing) so I took some spark out in a few places and the car woke-up.

I've never tuned an MS cam before, but this is looking more like a typical cam in a "sprtscar". I'd like to have an adjustable intake cam pulley. This is on 91-octane. I also took the new plugs and gapped them to .035" and the car would not run, lol. I was out of time so I threw the old plugs back in. Has anyone seen my feeler gauges?

Is that AFR map applicable for vacuum in turbo, Hustler?

/Steals it.

I don't know if you tune the cars yourself or have someone else do it, but this 11.5:1 ratio engine is a real bitch to get right on the street. The turbo cars are easy compared to this. The biggest problem with this car right now is the MS1,EV1 injectors, CKP from the stretchy timing belt, and no TPS. I may beg Karter69 to help me mod the MSpnp for TPS. I am out of scratch to buy injectors and I'm waiting on Dimitris to release his MS3 so I can give this engine the treatment it deserves.


Oh, that 4.10 will probably go in this weekend. John and I just talked about putting it together.

I tune all my cars now. If I have a real problem child, I take it to Shawn Church. He's one of the best in the country. Yup, 11.5:1 on 91 will be a bit of a dance between 4500~7000. Very sensitive to timing. We sometimes see 4-5whp per degree right up until det threshold. So you may end up leaving 6-10whp on the table or running race gas, depending on porting and cam timing. Crusher runs on race gas now. Still, 150whp can be safely reached on 91. Maybe just get it close for MHX and futz with it later. 140whp and sub 2100# with 9's will still be really quick. Those numbers will put it 2-s under SM record.

Which reminds me, have any of you TX guys run under SM records in an N/A yet? We're 2s under SM records with street tires on a full interior N/A daily driver now so that's the bar

I weigh 201lb right now too so that's not helping either. My dyno guy may be able to get to the shop this weekend so there is hope. I don't really want to run E85 on the car because it's too hard to find, but the only rubber fuel hose left in the car is at the fuel-pump, so I could easily run it on corn.

I may not have time to cut the weight, we'll see. We still have to get it balanced, aligned, tires mounted, get the dash swapped and I'm out all next week thanks to Hurricane Isaac.

John went 1.5 seconds under in his black, 120whp NA a couple years ago on Teins, I think I matched the SM record in his car in one session. I'm sure there are others out there but I don't know of them. Some of the south Texas crew has run under the record at a few tracks. John and I are both shooting for 1:27s in my car. We think the weight cut and diff will get us there. You guys are total cheating bastards with your perfect set-up and decades of seat time, lol.

I'm just super-pumped about having a car where I have zero concerns with drivetrain durability, although I know the concerns were unreasonable. I won't feel like I'm on borrowed time with the trans and turbo, just going to drive the **** out of the car and never even look at the gauges.

I'm also looking at TTC with this car which is unfortunate, but whatever.

No. You should go leaner from 70-95kpa than I am in this AFR table. I'll end up changing the AFR based upon output on the dyno. I expect this tune to take longer than any tune I've done. Seriously, tuning this engine makes anything below 10:1 look like cake.

Wow, there is a massive difference in the timing you can run between stock 99 compression and 11.5. I'm still not used to being able to get knock all that easily on NA engines until you get to high compression. I wonder if that wizard Keegan has some tricks to make this combo chamber significantly more knock resistant.

And looking closer you wont likely be able to see the difference on the street but try going as rich at 12.4 in the area around 4k, you might be able to squeeze some more torque out.

Wait until it sees the big dyno to draw conclusions.

I'm actually planning an EP style street car build with no gauges save shift lights and tiny digital speedo run off of GPS. It'll have a combo starter/ignition toggle and that's it. Fuel level gauge will be hidden in a little storage cubby behind a door. No ignition key, just a removable steering wheel and hidden kill switch.

No windshield frame but a small polycarbonate windshieldlet. 5 lb door skins welded shut. Kevlar/FRP lightweight semi- widebody, 10's with hand cut 245/40/15 DOT radials. 9000rpm 2.0L with big cams and IRTB's. Guessing 200whp on E85. 1750#. Probably silver with fat orange stripes. It'll be loud, stupid and insanely quick..and it will not have gauges.

Always trying to one-up me? I see my car to be more of a cross between your daily and Crusher, sans-aero since I don't have the TT points. Its a car I'll drive to work a couple days per month, the "poverty TT car". Hopefully a little lighter than the daily, a little less comfortable, no climate control, and a car that requires ear-buds on the road trip. One of these days I'll buy a car quiet enough to use Google Voice Search while driving, that day is not today.
