Seem Right???

Post by PairOfS14s »

I went to the local 1/8th mile drag strip last weekend and wasn't happy with results. I had MAJOR traction problems and had to baby 1st gear and after shifting to 2nd, I would have to get completely off the gas and then roll back into it then fight wheel when I hit 3rd. Not sure on my power output but I would assume 250ish so that wasn't the problem. Either way, my trap speeds seem really high but ETs are high too. If I gain traction, will my trap speeds drop somehow? My MPH was the same as another guy I know with an S10 that ran mid 7s...

Your trap speed seems wrong. I ran a 9.1 @ 79 with ~240 whp.

I know it seems high but I've been to the track 3 times and that speed is consistent. My buddies are running mid-high 8s at 85-88mph at same track. I've ran as high at 97mph on a 9.3 pass blowing tires off for 300'ish

250-300whp will not trap 94-97mph unless you have the motor in a starlet

I know but on the street, I outrun the same people that runs 90mph on track. One of my track passes was against a friends mustang that launches HARD. He ran a 8.9 at 81mph and I ran a 9.2 at 94. He said he look in mirror and said "Holy **** he is closing fast". If I had 20' more, I would have blew by him. Something just don't make sense! There is no way I have more power than 260!

You have a high trap speed for a sr t25 unless you have a t28 but even a t28 would need 15+psi to run 94mph in a 1/8th. U must have a really healthy motor, perfect tune and a few piss stains. What rpm r u passing the traps at?

Its T28. On a motor that I said was in its last days right before I boosted it 2 years ago. I shift at 6k-6500 but I run 3rd to 7000ish to keep from shifting at the line. I have had to grab 4th once.

Like I said above, a guy I know ran a 7.7 @ 95mph same day in same lane as this slip so the radar isn't off. That and in the last year, I have been down the track 10-15 times and I have only had one pass under 90mph and it was 10.0 @ 88mph when I almost lost car in 2nd.

Maybe your boost gauge is off or your reading it wrong. A lot of times from different angles you see 11 and it's really 15 or the gauge could be a bad. My uncle's car was hitting 30psi doing a weak burn out I told him that's not possible I let him use mine he was boosting 12psi. Maybe your wg is spiking could be weak springs. But at 11psi I highly doubt it man you have to be running at least 15. Your doing the same trap speed I was doing last year on 14psi. I ran 7.4. Ifyou hook your car should run mid.11s

Ok but no matter the boost, I have yet to hear of 275whp being possible on stock maf or 370cc injectors. That's my 3rd boost gauge in car and they have all been at same psi. When I go back, I will try to get video. We are planning a 1/4 mile trip this spring (closest 1/4 is over 2 hours away) and we have all estimated mid 12s as my car sits tires and all.

Mathimatically, if i trap 90+ in the first 1/8th, the second eighth should take between 3.6-3.8 seconds if I can climb to 115-120mph.

You laugh about mid 12s but guess low-mid 13s.... My times vary more than that in an 1/8th so I would call them both good guesses
