Paul di Resta believes it will take up to two years before Force India's cash boost fully translates into on-track progress.
The team's board approved a £50 million investment programme last month in a bid to improve its technology.
Di Resta reckons 2013 will be too early to notice the effect of the financial injection.
But the Scot has no doubts about the long-term potential of the investment.
"I think ultimately you shouldn't really be looking at next year because I think you should be looking a year back and then two years forward," said di Resta.
"The foundations are obviously getting bigger and there's a great level of investment coming.
"For a team like this you will get true benefits for it, but I think you see that for years to come as opposed to the near future.
"Given the way this team works and the small network it has, I think it will build upon something."
Force India finished in seventh position in the constructors' championship this year, dropping one place compared to 2011 after being beaten to sixth by Sauber.
The Silverstone squad endured a slow start to the season before it raised its game in the second half, something that di Resta hopes is rectified for 2013, when he hopes to kick off the campaign in strong fashion.
"That is always one thing that seems to happen," he said. "I think it certainly showed with the team last year. The performance we had last year, it would have been nice to start with that.
"I suppose in some ways you can be happy that the rules aren't changing too much next year because the car will be much stronger next year as it is only an evolution that we will be using.
"So there's no great philosophy change really, it's just working on the small things really. The things that make a difference."
