you bet it can, Accufab owner and racer John Mihovetz ran a 6.19@235mph (380km/h) on the weekend in Las Vegas with a Ford Modular engine. John uses the 4.6L (full alloy available only in US Mustangs 1996-2009) yes 4.6L 32-valve quad cam. 281ci with twin 80mm turbo's making 2500hp on 50psi of boost. what makes it more impressive is John uses the factory block and heads. runs an aftermarket crank now but John has went 6.25@230 using the factory crank. also uses the factory followers and lifters in the heads.
what a brilliant motor Ford has provided as a basis to start on not just a drag combo, but also on the street. here is a video of the pass and interview with John afterwards http://www.youtube.com/watch?v=86uLwXstuWQ |

Those times are amazing for such a small engine.
But I wonder what would happen if Doorslammers used turbo's?

Isn't the Acufab car the old Aeromotive car? If it is then there is a write up in Muscle Mustang magazine. I think it's a Duttweiler engine and there is nothing stock about the block and the heads apart from the castings. The heads are fully developed and the original block has 8 custom made Darton sleves. That is if its the same engine that is still in it, I met the new owner last year at Fontana, he was racing in the Pacific Street Car Association (PSCA) and went 6.40's, its a killer car but there wouldn't be a nut or bolt legal on it for Top Doorslammer:

![]() you would be hard pressed finding any other engine apart from the 2JZ and Ford Modular making over 2000hp with factory cast heads (ported), block (may be grout filled) and crank. that is a pretty fantastic effort using factory castings from Ford and Toyota.

![]() ![]() it can get costly, i'd hate to pay your bills ![]() i'm familiar with the Lexus 1UZ engines, we have one in a Capri (street car) running low 8's. the Gullotto's Soarer is a weapon, it's one of the cars that made me want to build what i am. im a big fan of the small cube DOHC 8's. i am actually thinking about running BB/API when i race ANDRA events, Ash Hamblin (who is also now putting a 4L Lexus in his altered) has been talking me into it. i think he was saying around 2400lbs like u said. my car should come in at about 2500lbs so would be perfect. if i can run a similar time to what the Gullotto's are i would be one happy boy. 40psi with a 4.6 would see close to 1800hp+, in a 2400lb car you'd be looking at a mid-6@210 on a perfect pass. oh n if ur ever selling the BA shell let me know if i have the money i will buy it ![]() Last edited by prasac; 30-05-2011 at 08:38 PM. |

Does it really matter what power it makes ??
As long as it does the times.. The Hemi has a fair few years behind it.. Aftermarket block and helped with rules too...

Back in 1994 we (Martin Stamatis driving) ran 6.0 in a rail in CC/Dragster at 343ci. ANDRA changed the rules so we couldn't run the car in that class anymore, at the time we had gone quicker than anyone in AA/D or BB/D or T/A which are all classes that are meant to be a lot quicker than CC/D. I'm the first guy that would love to see the rules opened up so that smaller engines could run competativley but it ain't going to happen. NHRA Pro Mod allows Turbo EFI, Blown or Nitrous combos. ANDRA T/D only allows Blown mechanical injection. The Mod Motor has a lot of potential there is no doubt about it I mean look at the Super Snakes running in the 8's practically out of the box, the AcuFab car and many others. It is an awesome motor.

no PM received Gonz. i have sent you one, let me know if u get it.
with a limit of 40psi, a stroked 4.6 gets u to 4.9L even 2530lbs wouldn't be too bad. anything over just get's a little ridiculous as the 4V Quad Cam EFI cars get slogged around 8.5lbs per cube. like u said a small cube UZ or modular are perfect. we make around 1200hp @ engine now with the 1UZ with 62mm turbo's @ 29psi. a pair of 67's with 40psi would have to pump out close to 1500hp. your minimum weight would only have to be 2040lbs. you'd probably never get that light, not sure what the Gullotto's weigh. i'd have to say close to 2300lbs. the heads on the mod motors are an extremely efficient factory head. love to see the Gullotto's throw something like that in the Soarer. shouldn't go giving them ideas ![]() ![]() Last edited by prasac; 31-05-2011 at 04:48 PM. |

they like those Toyota's
![]() mine is not far at all, just all the silly little jobs left like changing all the bolts on the lexan, doing the door gaps etc. the BA is steel bodied? damn that is even more impressive. here i was thinking it was CF or fibreglass. |

Any questions about the 1UZE, feel free to drop me a line I should be able to PM soon. Yes the car is all steel except for the fenders and bonnet which are fiberglas, it has real working tail lights, head lights, steel doors, real working door handles, on board starter motor and on board batteries, we tow it up, squirt some fuel in the hat and hit the starter button. It also has an on board primer for the fuel but the crew won't let me use because they say it looks stupid with them standing around doing nothing! My favorite is the horn, don't you hate it when your strapped in the car and the crew ignores you? Not anymore !! Its got a modified Lenco drive with one of our bolt together aluminium converters (look ma no clutch). Its about 200lb overweight, I can loose the starter and the batteries, do a carbon front and trim a little steel off the body but It all costs money and I lost all my sponsors while ANDRA ran me around in circles for 10 years over the back wing, they wouldn't issue a log book! The new tech guy sorted it out in Feb this year and we hit the track at the next meeting 6.59 off the trailer as a SS/AA doing a before the startline burnout, after 10 years I was happy! I havent seen 9000 yet, 10,500 is where we need to be, they pick up nearly 10lb of boost in the last 1500rpm! Gonz

Hmm ?? See how good my P/G 4000 converter works...
On my 1UZ turbo Celica.. No guessing...

Gonz, have heard alot of problems with tech problems over the last few years. it sucks to have built a car and denied racing because of something small. the BA Baracus would make an excellent Outlaw 10.5 car like Frank Mamone's. if the APSA ever has an event out at the Plex be good to see it out there.
i have noticed a couple Aussie companies making bolt togethers now u guys and Slingshot. how are your turbo converters going? i know in the past Aussie converters not being able to get the R&D like the yanks they were lagging behind a little bit ![]() we had an Aussie one in the Capri, was taking about 7-8 seconds to come up on boost, we put in a Chance it now takes about 2 seconds. |

We do a lot of Turbo converters, the spool time has a lot to do with a lot of different things but generally you should be able to get full boost from the first amber to the last amber, so about 1.2 seconds.
We have a few little tricks that make it happen but you really have to find a balance between spool time and lockup % if you get everything right you can get them to hit full (or launch) boost within a couple of seconds and only have 3 to 4% slip through the top. There are 6 factors that are out of (our) the torque converter manufacturers control: 1. R/A ratio on the turbine housing 2. Turbo size in particular turbine wheel size 3. Compression ratio 4. Cam size and timing 5. The tune 6. Size of the engine Factory style 1UZE's have a fair bit of comp (I think about 10:1) and if the turbo size isn't stupid BIG they spool up good and fast. As the comp gets lower and the cam gets bigger and the turbo gets bigger, the engines ability to make low down torque is diminished. A torque converters stall speed is dependant on the torque that the engine makes, till the engine makes boost the torque will be low and the stall will hold the engine at a lower RPM. Engine timing is another factor (and overall Tune), I've seen cars that you can hold wide open (throttle) and they will stall the converter at 1600 to 2000 RPM and do nothing, add 2 degrees of timing and they come straight up on full boost. We are lucky in the fact that we build our own test cars to test this kind of stuff so we learn what works and what doesn't without someone else paying for it. The NCRC stuff is well built and strong, the billet aluminium pump that both they and Coan and couple of other guys sell are real nice. Gonz

tune played a big part in ours not getting up on boost. then Rigoli had a go and it was MUCH better. 8.5:1 comp on the 1UZ, the new engine we build for it will have 10:1, we are thinking of putting bigger turbo's (67mm) on it. it does good spooling 2 x 62mm see how it goes when we step them up. my lil 4.6 has 2 x 75mm turbo's be interesting to see it spool 'em up with only 9.5:1 CR, i have 11.5:1 CR pistons but went with the street pistons first see how we go everything might fall into place.
good to see people on the job for the turbo guys alot of people just tend to concerntrate on the NA & Blown converters, alot of turbo cars coming out now. |

well done to John Mihovetz and the Accufab/Lucas Oil team, the Mustang this weekend PB'd twice and was running consistent 6's all weekend. ran a 6.16@235 and a 6.14@236.34mph bests. 281ci 4.6L 4V modular with twin 80mm turbo's.
incrementals for 6.16 run R/T .163 60' 0.993 330' 2.727 1/8 4.075 MPH 184.980 1000' 5.212 1/4 6.167 MPH 235.56 and 6.14 run R/T .241 60' 1.021 330' 2.722 1/8 4.058 MPH 185.820 1000' 5.189 1/4 6.141 MPH 236.34 |

i thought it would be an interesting comparison to see just how much difference a turbo big cube engine makes in the deep end compared to a small cube turbo motor. here are Campo's increments from his 260mph pass
60 - 1.038 330 - 2.750 660' - 4.039 @ 197.48 1000' - 5.088 1320' - 5.958 @ 260.31 both Campo and Mihovetz push similar boost around 50psi and weigh the same, notice the front half off the track very similar numbers. the small cube motor is actually quicker to 330' by 3/100ths, a little after that is when Campo can really put the power down, he is 2/100ths and 14mph quicker at half track. after that it's all she wrote, a difference of 2/10ths and a huge 24mph at the end, at this point Mihovetz is pushing out 2500hp and Campo is up around 3000hp+. |

http://www.youtube.com/watch?v=vIDQtZ7fshA the 6.16 pass is at 1:10, the thing is like a bullet out the hole. shame he broke thru the beams and redlit, he would have given the Corvette a good run.

new PB, Mihovetz ran a 6.083@236.84mph this morning and backed it up with a 6.140@236.55 how consistent is that for a little 281ci twin turbo engine.

video of the 6.08 pass is up http://www.youtube.com/watch?v=CNPNxbEQX8Y got a bit smokey from 1/2 track on but there was no damage. John even went back to the office to do some work between rounds, the track is very close to Accufab
