DC-Auto New Member 24 Member For: 9y 1m 4d Gender: Male Location: GOLD COAST, QLD Posted 27/02/18 11:26 AM Author Share Posted 27/02/18 11:26 AM (edited) it has been a while since I have made any updates, I have been doing some tuning with Ash Mason from Wiring and Tuning Solutions, and we have ran into a few small problems with sensors and fuel pumps which has limited our tuning sessions. So far the results are promising but we are far from our 26-28psi tuning targets, and so far we have only had a chance to tune on pump 98 fuel, don't forget this is through a 1500hp transbraked TH400 with a 3500rpm stall which robs power. 9.7psi = 524rwhp 14psi = 571rwhp 16psi = 593rwhp 17psi = 609rwhp We are expecting over 700rwhp on pump 98 at 28psi, but our tuning was cut short, the 10yr old Bosch 044's were getting tired and fuel pressure was dropping off at 7000rpm. Since last post, I have done a little more work, Racepack street dash has gone in to compliment the Haltech elite information. TrueTrack and diff rebuild with 3.45:1 gearing, CVR Brake vacuum pump has been installed as I have about -3" of vacuum without it. New mac electronic boost solenoid as my old one had died, and a magnafuel pro tuner 750 (2000hp rated) fuel pump and new fuel lines 9psi Dyno run Atomic cams Edited 27/02/18 11:28 AM by DC-Auto Link to comment Share on other sites More sharing options...

eff xr6t Member 569 Member For: 11y 3m 17d Posted 27/02/18 11:56 AM Share Posted 27/02/18 11:56 AM I wouldn't say happy Dyno I'd just say efficient motor. I tuned my mates single cam and made 390kw on 5-6psi... if it's got a set of cams that make use of the efficiency then it's easily doable. Link to comment Share on other sites More sharing options...

Dyno is just a tuning tool, anyway let's see what it runs on the strip Link to comment Share on other sites More sharing options...
eff xr6t Member 569 Member For: 11y 3m 17d Posted 27/02/18 12:32 PM Share Posted 27/02/18 12:32 PM It runs 10.8 manual with 390kw haha. I think you will be suprised with what your own car will make if you even get it running again... big turbo makes the power easyer to achieve and you've got size in that department covered.

Cams make all the difference to power up in the 7k + zone. Doesn't even compare to standard cams at 6k In the old days cams and upping the compression were the things to produce big peak power. These days you just add e85 and crank up the timing and boost Edited 27/02/18 01:26 PM by arronm Link to comment Share on other sites More sharing options...
