Title: Updating my 1915cc, help needed! Post by: Jesse/DVK on October 12, 2010, 22:48:55 pm So guys, winter is around the corner and I want to update my 1915cc.
Current specs: AS41 DPR 69mm C/W SCAT I Beams Mahle pistons + cilinders Engle FK-8 , CB straight cut CB lightweight lifters Manton pushrods 1.4 rockers 123 ignition (009) 1 1/2inch merged header 041 heads 39x35.5 (small porting) Weber 48 IDA's Gearbox is a built one with weddle sidecover, superdiff, SAW axles, 4.12 R/P . 3.78, 2.06, 1.04, 1.44. Looking to upgrade my heads, exhaust and ignition. Exhaust I would like to have a A1 header + muffler (only 1 3/4 inch?) Igntion Petronix Ignitor 2 or CB Perf. Magnaspark 2? Any difference? Heads.. don't have clue which to get? Steve Timms? CB Wedgeports? Is 160-170 bhp possible?? Thanks! Title: Re: Updating my 1915cc, help needed! Post by: Jim Ratto on October 12, 2010, 23:11:17 pm I always suggest Jeff Denham for headwork, as I am sure anybody else that has dealt with Jeff would. You might ask him about his non-welded 40mm or 42mm x 37.5mm, like he did for Harry. They would keep air speed up (good thing for stock stroke motor with big carbs) and run cool. I don't think you need a 1-3/4" header, I'm sure the 1-5/8 would better suit your displacement and keep torque band nice and wide, yet still breathe up top.

I just contacted Jeff for his advice. Title: Re: Updating my 1915cc, help needed! Post by: Jim Ratto on October 13, 2010, 21:51:05 pm ;D I just like to get the most out of streetable sub 2 liter :).

Title: Re: Updating my 1915cc, help needed! Post by: Jesse/DVK on October 14, 2010, 09:12:33 am A pair of 44x37,5 welded heads should do the trick according to JD.
:o ;D Title: Re: Updating my 1915cc, help needed! Post by: GreenTom on October 14, 2010, 10:54:03 am 160 ouof 1914 with small heads won't be a easy task.
my fried's 1914 with 40x35,5 los banditos ported with about 9ish:1 CR C45, and as I remeber 1,1:1 on 40 DRLA's ,1 5/8 merged VWSpeedshop header with 2,5" turbo muffler of VWSS also did 127HP and 154 Torque. here is he graph. (http://liri.nab.pl/garbus/6.JPG) I use Pertronix distributor with Ignitor II and flametower I coil (the car abowe has the same as me but ignitor I). Works really grate smooth and powerfull. Title: Re: Updating my 1915cc, help needed! Post by: lawrence on October 14, 2010, 16:45:15 pm Cool thread! Did Jeff Denham give any recommendation on camshaft and compression ratio? You may want to consider the 1 5/8s A-1 sidewinder. It looks good and from what Tiger says it make just as much, if not more, power than a standard merged exhaust. The magnaflow mufflers they sell are nice too! Talk to Tiger he will set you up. 160 hp is definitely possible. Let us know how things progress. I really like 1914s as well. ;D
I have had good luck with the Mallory Unilite distributor and VI-AL igniton box, but it is important to get the proper coil for this setup. At first I had a "standard" liquid filled coil mounted on the case. Bad idea! The bakelite top cracked and the cooling fluid leaked out. Excessive heat or vibration could have caused this, Im not sure. I called Mallory and they told me I had the wrong coil, so they sent me the correct one. Its a small coil pack with aluminum heatsink fins. Its an awkward size, so I mounted it underneath the parcel tray above the transaxle. Title: Re: Updating my 1915cc, help needed! Post by: Jesse/DVK on October 15, 2010, 08:20:23 am Mm, I really don't like the look of the sidewinder. It's not a Cal-look exhaust to me :). JD, said that 180hp is possible with the FK-8 and his heads :D :D. Using a 1 3/4 inch lowdown header.
Anyone knows if my Berg traction bar will still fit with the lowdown header? Mallory is also an option! Title: Re: Updating my 1915cc, help needed! Post by: Rennsurfer on October 15, 2010, 08:30:42 am I agree with Jim... the 1 5/8" diameter would suit your engine very well.
Mm, I really don't like the look of the sidewinder. It's not a Cal-look exhaust to me :). To each their own, but this is exactly why I had one made. I hate rules. Title: Re: Updating my 1915cc, help needed! Post by: Felix/DFL on October 15, 2010, 11:28:30 am The power ALWAYS lays in the head(s). Think about it it`s ambiguous ;)
When you mount a low down header you can`t drive dual packs that fit under the car... Total seals (2nd) would even be an option to think about. And don`t forget to open up the manifolds top 2 bottom.

Its a small coil pack with aluminum heatsink fins. Its an awkward size, so I mounted it underneath the parcel tray above the transaxle. Never mount the coil to case or motor...The vibrations kill the coils quick. I drive a Mallory 29440 (really like the look/ like old rubber batterys) with an 009 & Ignitor and Mallory Hyfire 6 and are pleased with it. Coil is mounted with rubber dampers on the sidewall, Mallory-box under the rearseat even rubber mounted to get away the vibrations. No Probs so far. Have fun updating an engine is always nice! Title: Re: Updating my 1915cc, help needed! Post by: Jesse/DVK on October 15, 2010, 11:42:57 am Thanks for the replies guys. I won't use dual packs I will use the lowdown muffler with it. But will a Berg traction bar fit?
My coil is mounted to the firewall using a jaycee mount and rubbers so should be fine. Really lookin forward to update the engine this winter and run some better numbers next year on DFL 402 and DDD :) Title: Re: Updating my 1915cc, help needed! Post by: ugly duckling on October 16, 2010, 05:08:02 am so is somebody doubting my word that it wouldent make 180FWhp :D :D :D. there is no reason why it wouldent. UD .
Title: Re: Updating my 1915cc, help needed! Post by: ugly duckling on October 16, 2010, 05:49:24 am it would be nice if you had some 1.6 rockers to go with your 380+ cam lift. 611total is a more ;D ;D lift. a 1915 can make a 100hp on stock heads NO PORTING with a good 3 angle valve job blended slightly with a BABY cheater cam. you've got the BORE that's whats important. just my two bits . UD .

AMEN, Mark, rules are meant to be broken. Besides the Sidewinder IS a cool exhaust. Sometimes mixing old with new is ok. ;DMm, I really don't like the look of the sidewinder.

Jeff is right, I got a 180+ with my K-8 way back, and I think you can use a traction bar, works with s small spacer, thats what Tiger told me with my first Lowdown system, but ended up using a kafer bar type set-up instead, works really well, no wheel hop at all.Anyone knows if my Berg traction bar will still fit with the lowdown header? Mallory is also an option! Ted 8) |
