Volvokiller Posted August 9, 2005 Report Share Posted August 9, 2005 Previous topic, info, and observations here - http://volvospeed.com/vs_forum/index.php?s...pic=28104&st=15Quick overview of setup - Lpt block (88k miles), 16t (~60k miles), 350cc white injectors, IPD chip for Lpt, IPD cat-back, stock downpipe, k&n panel filter.As stated in the last thread, the car was making a solid 12 lbs of boost on the highway, spiking to 14-15 on shifts, and then settling down around 12 lbs again. The car felt noticably faster with the 16t compared to the 13g. The wideband readings were 10.7-11.3 under boost.Drove 800 miles down to Alabama for T-Bricks SE4.0 meet. Got around 26-27mpg with the A/C on the whole time.Friday night was spent at the drag strip. I ran consistant high 14's at 93.xx mph. Lowest ET all night was 14.82, highest trap was 93.75 mph. Observations:1. The car was only making 10.5 lbs of boost at the track. It was really hot, and hard to cool the car between runs. It didn't matter if the runs were 5 minutes apart or 1hour, the times were the same.2. You don't need 350cc injectors if you plan to use the IPD Lpt chip. Halfway through the night, we swapped in the orange/red injectors that came stock on the car. The AFR's barely moved. Maybe .1-.3 leaner. Still deep into the 11's with dips around 10.7.3. 60ft times were worse with the 16t than with the 13g. I could cut consistant 2.20's with the 13g. Lowest with the 16t was 2.34. Although, this is at two different racetracks.I left the dragstrip slightly dissappointed. I figured I could run 14.6 at 94.xx mph. I'm sure at 12 lbs this would have been possible, so I was really just disappointed that the car was only making 10.5 lbs.Saturday was spent at the dyno. My car was the first to strap down and I actually ended up driving it to make sure it stayed in 3rd gear. With the 315cc injectors, 10.5 lbs of boost, and air temps around 90 deg, the car made 202.79 hp @ 5600 rpm and 212.54 lb-ft of torque at 4500 rpm. AFR's were in the high 10's.Back on the highway, the car kept making 12 lbs compared to the 10.5 on the dyno and at the strip. This being my first turbo car, is this a common observation? I understand that boost pressure can be sensitve to heat and humidity, and dependant on air flow to the intercooler. I suppose its possible that on the highway, the car maintains a lower temperature and the air force generated cannot be duplicated by large dyno fans.Anyway, I'm resonably happy with the results. The car pulls alot nicer on the highway when its making 12 lbs. I do have a MBC that I may try to hook up and run more boost, but I'd rather not blow up my daily driver.Well hopefully some on here find this helpful. I haven't decided whether to pony up the additional $400 that IPD wants for a reflash to a map designed for this particular block/turbo combination. I'll keep you guys updated if I do.Chris Link to comment Share on other sites More sharing options...
the underlørd Posted August 9, 2005 Report Share Posted August 9, 2005 nice work Chris... I should mail you my 98 LPT ECU tuned for the 18T and see how that works! lol.. Link to comment Share on other sites More sharing options...
Guest DougK Posted August 9, 2005 Report Share Posted August 9, 2005 Chris, I wouldn't be dissapointed.You made 20 more WHP than I did at similar boost and AFR's. The heat was a problem for us too. There is ALOT of potential in there.. I honestly doubt mine would run a 14.8 in this weather at 10psi. Link to comment Share on other sites More sharing options...
lax01 Posted August 9, 2005 Report Share Posted August 9, 2005 the 60 foot times are definitely affected by the heat...turn the boost up Chris...I know Jon wants to goto Capital...I'll go but I think I'll just watch... Link to comment Share on other sites More sharing options...
Volvokiller Posted August 9, 2005 Author Report Share Posted August 9, 2005 Thanks for the positive comments I'd like to think there is another 30 wheel horsepower at 12-13 lbs and AFR's in the mid 12's.... but who knows. I'm pretty happy the way its worked out so far. At least the engine is still in one piece Josh, I'd like to go back to Capitol when its cooler. I ran a stock Evo (it did have an exhaust) in NC (about 78 deg outside) on the way home from 70-120. He only pulled one car length on me. I was pleasntly surprised :) Link to comment Share on other sites More sharing options...
JoshV70 Posted August 9, 2005 Report Share Posted August 9, 2005 Don't be disappointed about your quarter mile runs. I have a 16t with the orange injectors, and an mbc set at 15 psi. The day I went to the track, it was about 95 degrees out. Definitely not great for turboed cars. The best I ran was 14.776 at 91.53 mph. Link to comment Share on other sites More sharing options...
kenhoeve Posted August 9, 2005 Report Share Posted August 9, 2005 Chris, I wouldn't be dissapointed.You made 20 more WHP than I did at similar boost and AFR's. ←True, but your car also ran 14.2@99 with less tuning than it now sits at so...

JESSEXC Posted August 10, 2005 Report Share Posted August 10, 2005 Here is a dyno run I did with the 13g., Both where done the same day. Nothing was changed. Look at the difference in the A/F and the hp increase. Link to comment Share on other sites More sharing options...
98BRICK Posted August 10, 2005 Report Share Posted August 10, 2005 VolvoKiller...shoodnt the white injectors allow u to run more boost effectively???? Link to comment Share on other sites More sharing options...
sp5368 Posted August 10, 2005 Report Share Posted August 10, 2005 4 runs white injectors 98 t5 ecu and 13g speedtuning program 12 psi whites are to much Link to comment Share on other sites More sharing options...
Volvokiller Posted August 10, 2005 Author Report Share Posted August 10, 2005 I think what we are seeing here is that for chips designed for the 13g, you can swap in a 16t turbo, and still use the stock injectors at low boost (~12psi) levels. Perhaps if you get a re-map for a 16t specific map (and/or more boost), you'll need the larger 350 cc injectors. I don't really feel like pushing the limits of the lpt block quite yet buy turning up the boost. Link to comment Share on other sites More sharing options...
sp5368 Posted August 10, 2005 Report Share Posted August 10, 2005 I agree from what I have seen from my dynos orange injectors is the way to go, I think I am going with a Rica chip to figure this out. I have spent so much on dynos and I am still in the same spot. I guess to play I will have to pay, now if I can only slip it by my wife. Link to comment Share on other sites More sharing options...
Volvokiller Posted September 8, 2005 Author Report Share Posted September 8, 2005 Well, just thought I'd update everyone on the status of my swap.3000 miles in, everything seems to be fine. The car gets similar (if not better) gas milage with the larger turbo (I manage to drive off boost 90% of the time). I usually see 22-23 city.We unhooked the WB so I can't comment on the AFR's but for the three weeks the LM-1 was running I never saw any on-boost AFRs above 11.5. So the car is still running rich with the IPD chip and stock 315cc injectors.I plan to head back to the dragstrip when the weather cools a little more to see if I can get some better times.
