That looks like a FUN engine to drive. What kind of ignition are you running and what was the timing set at? |

Ignition is a Mallory Unilite vacuum dist with the gray springs; Bosch blue coil & Bosch wires; NGK plugs. Ask Darren for the specific timing figures, I haven't checked them yet. _________________ `70 street Ghia, 2276 NA

gerrico DRD has built 3 engines for me. Recent motor is a 2276 with 44x37.5 heads (044) and made 206 @ 6500 and the torque is unreal. Your motor is a true street motor. My motor is a weekend worrier with the close gear tranny. Good choice on the specs, Darren pointed you in the rite direction for your application. Have fun. Drive safe |

Nice engine combo. I made several of them for street and Glamis sand rails. More pluses about this combo is that it can pass the Arizona emissions test for 67-72 VWs 5% co and 450HC and has enough torque you can use the stock transaxle on the street. |

Perrib, I see that you are from Mesa, I thought the 67 is ok now it does not need to have a emissions test, is this correct or hearsay? |

As of last May when I sold the shop you still had to get an emissions test for a 1967 vehicle. The law may have changed since. |

This engine will give you guys a idea on what can be done today with the parts and resources avaible today.
The owner and builder of the engine wanted to build a street driveable engine to drive anywere and last a long time, not a 1/4 mile engine with a high maintenance plan, and short life, pick one of the two, game over.
His engine will never see the track and was never inteneded to see the track. It not hard to click off a timeslip at a track, but to make the engine and power train last is another story.
With the bigger 42X37.5v DRD L6 heads, the torque would come in at the same rpms, and build more torque over the power band. This is were years of experience, flow bench data and dyno data come into the game. Years of collecting engine data will help the engine builder select the proper parts to build the right engine for the a given application.
The power of this street engine is pretty common at our shop, our dyno reads on the lower end of the scale compared to most dynos around.
It"s a no frills build, with the proper head design, cam selection, and carb selection. Get these right, and you have a engine that has a very good VE and builds a solid torque band.
Job well done Gerry! |
Darren, what size carb for the L6 with the 42mm intake valves assuming the same engine otherwise? Would you stick with the same cam? |

Dual 44m webers work really good with the l6 42X37.5 head, I have seen more torque,and a tad over 170hp with the same engine combo.
Torque is were it's at, the more torque, the harder the engine pulls. _________________ "DRD RACING HEADS"

Thanks for the response, Darren. So I assume there are no trade-offs going with the bigger heads (keeping everything else the same). I love my L3 heads and cant wait to build the big one |

Yes, that is a great RPM band, T/Q & H/P, looks like you have a well tuned engine and parts combo. There are no dips or humps, just a flat line T/Q across the driving range, and a climbing H/P line.
My turbo engine dyno graph mirrors yours from the 2500 to 6000 band too. _________________ All the QUICK & FAST VW STREET cars are TURBOED!!! |

Nice flat torque curve! Darren built me more of a weekend warrior 2276 that makes 150+ foot pounds of torque from 3,000 - 7,000 rpm's, peaking at 176 foot pounds at 6,000 rpm's. The compression is set at 10.2 to 1, running custom DRD heads with 44/37.5 valves, a variant of the Webcam 86c, 48 idf's, Mallory unilite ignition system, custom 1 3/4" ceramic coated exhaust by Tiger at A1. I'm still working on the car so I haven't installed it yet, but there is a video of my engine making its dyno pull right here:

I AM! This project has been going on so long now that it's a little disheartening. Now I'm having to send my trans back to get a leak fixed. The shop that I got the trans from is handling it professionally so far so I can't really say anything bad about them....it's just one thing after another and more and more money going out. I'm sure the car will be VERY cool when it's done....it's just been a long road!
Thanks for the comment,

The timming at full advance was 30 with no vac advance. With the vacum advance timming was 40 degees. The Final ARF was 12.9 I think.
You will a really nice street engine for sure.
Also to note, we will have some new heads comming out next year, based off a vw head casting, 1 set will be focused for max torque with street engines, and the second set of high output heads, designed to push the limits power on pump gas.
Good luck. _________________ "DRD RACING HEADS"

Another thing to be aware of, just because the power falls off on a 100% load on the dyno, dosent mean the power falls off, when the engine is in the car, the car will never put a load on the engine like a dyno will. |
Daren is right.
Just an update for you guys. The ghia's been down for complete rewiring, new brakes/rotors, and a few other goodies. Never the less it has seen some street miles and I can say with 100% assurance that the power most definitely does not fall off at 5500rpm or even at 6,000. In fact the few times that it has seen 6,300 rpm it was still pulling HARD. Seems to pull as hard in the top end of 3rd as it does in first. Even managed to scare a few passengers _________________ `70 street Ghia, 2276 NA

Good job Gerico, I'll be hitting the dyno in a few weeks, mines a bit smaller at 2176, with round ports, 8.5 comp, 120 cam and 40 Dells with 34 vents. |
